if I want to replace the factory speakers in the non-bose eldo, it as simple as buying new speakers and installing them? Are they traditional mounts, etc. Just want to make sure there is nothing custom about the way the factor speakers are installed...

correct
nothing special at all
will bolt right in
best buy sells speaker plug connectors which will plug into the stock speaker clip and give you a + and - speaker terminal

cool, I actually was working on my caddy yesterday and seen that it seems like a standard port for 6x9s. To install them though I need to take out the back seats correct? I ran the amp to power them at least so right now I have the factory ones powered..haha, obviously dont sound too good so need to put some new ones in.

Hey guys,

I am new to the group and will have more questions I am sure...I am already learning a lot here!...but for now, can you tell me if I can easily upgrade a 1996 Sedan Deville stock system to a Bose system? I have a '96 Deville that I am selling to my brother in law...I just bought another 96 Deville for a good deal. The "new" car is in better mechanical shape. The only problem is the one I'm selling has the better trim (soft-top, heated seats, and the BOSE system with12 disc changer)...I have a new after-market head unit with DVD and only want to swap the Bose amps and speakers if I can...if not I will have to shell out $$$ for a new system. Are all of the 96 Devilles prewired for the premium sound? Can I easily just remove and install the Bose speakers and the amp in my "new" Deville? Please let know....Again Thank you in advance!!!

STS2003 I am too new to PM you so I've posted this on three threads so far...hope to hear from you soon!

Question about 2003 Cadillac CTS non Bose:

I know that it has a 5 1/4", can an adapter be had to upgrade to the 6 3/4" size of the bose system. I don't want the bose speaker, just to be able to fit a 6 3/4" speaker. Thanks!

have to have a custom spacer plate built

10-20-08, 04:44 PM
I just bought a 2000 Deville DHS (has Bose) and I noticed in the 4 hours I drove in it on Saturday that the Bose system doesn't have the kinda bass response I've gotten used to get in my VW Touareg (Monsoon-kinda stereo)....and I was wondering what I could do to change that..without putting in a sub and all that. (I've done that plenty in the past..not looking to again)

I see the speaker size is said to be 6.5 at the start of this thread..but then on Crutchfield and on this same thread I see 5.25 mentioned. Per Crutchfield, a 6.5 can't fit in this spot. I'm not looking for modifications....so what is the deal? (confused)

Another question....if I buy after market speakers, how many watts per channel (on the Bose) is it powering..RMS? (I'd rather not have to buy an amp and all that if I can just replace the 5.25? speakers in my front and rear door with something better like JBL, Alpine, etc.

This spacer that got brought up....how much extra does that cost on install? If it's just something simple, I'd be open to it....if something costly..probably not. I paid $6000 (119k miles) for this vehicle and I'm not looking to make it a $$ pit.

Thanks for any thoughts or feedback.

if you want some more low end without a huge cost look into the infinity bass link
its a small self enclosed powered sub which will probably be just what your looking for...

Witt
10-20-08, 05:17 PM
I know about the bass-link, but I'd rather not go the sub route..etc. Any thoughts about the speakers..sizes..?

Thanks.

CadillacSTS42005
10-20-08, 08:41 PM
you want more low end
so youll replace your speakers....

speakers are not powerful enough nor designed to highly increase low end

if you want more bass youll need to add subs its that simple
especially since the stock amp will cut base at higher volume levels like its supposed to..

Witt
10-21-08, 11:36 AM
As mentioned previously, I've had subs before (in 3 other vehicles)..I understand how bass works..lol.

I'm not looking to go the subs route as it's a pain, takes up space, and easily more $$.

Maybe I didn't ask this right....has anyone out there replaced the stock speakers in the front..and had good luck getting some better bass response in doing so? If so, which model of speakers, etc. (You can get better bass response without needing to add a sub)

I'm not looking to have a speaker on wheels....I'm just looking to upgrade the factory speakers..and trying to get a better understanding of how many watts per channel the bose system is putting out..

CadillacSTS42005
10-21-08, 10:13 PM
bose runs 1 ohm
any drop in speaker you replace it with will cut the power sent to it in half

so back to square one

replace the stock sub with a kicker free air one?

Witt
10-22-08, 11:53 AM
STS,

Iíll amuse this idea just to see where it takes me. The ďfactory subĒ in the vehicle, where is it located..I ask because I havenít run across it yet. I assume it to be on the rear deck of the vehicle firing into the back window area. Surely itís a tiny space, and obviously since Iím hearing poor bass with the system itself, itís nearly going unnoticed. That said, what would be your exact recommendation for replacing that item..without modification? (Iím aware the Infinity unit has a built in amp..self powered..but I assume that it wont fit this application)

Back to the speakersÖ.they suck. If I get some JBLs, Alpine, Infinity, etcÖ.will the existing Bose amp(s) be ok to power those to improve sound? Iím not needing to be blasted out, Iím merely wondering if the Bose amplification would be enough to even provide weak power to after-market speakers? (Iím not looking to have new amps and all that)

Thanks.

CadillacSTS42005
10-22-08, 10:46 PM
dead center in the rear deck
its a 10 inch free air sub
2 ohm
75-125 watts stock i believe

will the stock amp power them
sure
but its a 275 watt amp
figure 75 for the sub
thats 200 watts per channel at 1 ohm
so 50 watts per channel at 1 ohm
hook up a JL speak thats 4 ohms now your only using 12.5 watts
hook up a Infinity Kappa 2 ohm and now your only using 50 watts

and no one makes a 1 ohm speak other than bose.

Witt
10-23-08, 03:39 PM
STS....since I cant post a link (new member), I will mention the Kicker 10" free air $89 on Crutchfield....I would see this as a decent, cheap, replacement....and the factory power would be ample....(per your post I assume..)

Thanks for the detail....loved it.

CadillacSTS42005
10-23-08, 06:05 PM
not a problem
thats a good bang for buck sub nothing earth shattering but an improvement over stock without getting crazy
id recommend adding an external amp which has speaker level inputs to power it
connect the stock sub wiring to the speaker level inputs
then power the sub with the amp
powering the amp is cake since the battery is under the rear seat so no need to run amp wires the length of your car.

Whats up everone havent posted in 4ever! Getting the stuff to do a major audio upgrade. Just got a Rockford Fosgate Type RF X7 1500w. Ive heard from many RF fans that the birth sheets on these babies ranged from 1700-1900wrms! I wanted to test it out when I first got it, so I took a trip to my bro's house. He's got a bd1000 pushin' 2 S12L7 solobarics w/ a box as big as his little chevy malibu will fit. We tested the amp for about 1/2 hour on his 12's, adjusting the gain up then down adding a little more bass boost via bass knob, never did turn them both all the way up, as he was a little scared to, but I dont blame him. It made his radar detector drop right off the windshield, was kinda funny. Its a mean amp:want:.

But anyways, Im planning on getting 1 S15L7 4 ohm and a 2 farad cap. Gonna build my own vented box out of 1" MDF. Was gonna get a 10" solo-x but my jaw dropped after I figure the price of the sub and box. I also plan on taking all the carpet out and dynomating the entire trunk, then put it back together so it still looks good. Now I know the stock radio is not gonna be able to overpower the bass but I freakin love the finger controls on the steering wheel.

And this is were I need your help Jason! What head unit will match the controls on the wheel? Also, what kinda interior speaks you suggest?

Thanks man,
Greg

Got a 4 Farad Kole Audio Cap few days ago, 150a breaker installed ready for the box build. Get ready for some pics its gonna be bad! My first box build....

Thanks for all your help with all this. I blew my sub and now that i have it out i see where it has come unsealed around half the speaker. Probably age, Texas heat and I was listening to the Muse when i blew it!

I just want what i had. No amps, nothing...SO I cant just go buy any ol sub?
What are the specs i need?
Ohms? Watts? Free Air?
Can someone please suggest me a replacement?

To get more effective bass from your Bose system, set the bass all the way up, set the midrange all the way down, and then set the treble up about halfway and crank up the volume. :thumbsup:

Just curious if anyone knows if its possible to replace my front 4x6 speakers with 5.25 speakers in my 1986 Cadillac Fleetwood Brougham (RWD)?

...I replaced front and backs a couple years ago with Polk Audio MOMO's, but im still not happy with the clarity and depth of the front 4x6's.

Also, what will the difference be if I add in an amplifier to my speakers right now?...is it just to make them more louder or more crisp?

Thanks,

How can I tell if i have the Delco Bose Gold System. The head unit in the car is Delco Bose, but looks like it is an aftermarket one (see pic), but the rear speakers are blown. From what I am reading, you just cannot go out and buy any brand of speakers of the same size and install them. Why is that? One other question, it is not a speaker question, but does pretain to the radio system, how do you test a power antenna to see if it works before installing in your car? I found an antenna at a junk yark that was in the down position, so I figure it must still work, since most antennas that dont work are usually stuck up. Oh this is for a 92 Fleetwood FWD.

but its a 275 watt amp

thats 200 watts per channel at 1 ohm
so 50 watts per channel at 1 ohm
hook up a JL speak thats 4 ohms now your only using 12.5 watts
hook up a Infinity Kappa 2 ohm and now your only using 50 watts

and no one makes a 1 ohm speak other than bose.

So this would mean that Bose runs a 2 ohm sub and 1 ohm speakers?
or is that 2 ohm related to the Kicker Free-Air use sub you suggested?

I removed my aftermarket sub / amp a while back because the amp went bad causing the sub to go out too (when the amp powered on it caused the sub to bottom out several times then it was done before I could do anything about it).

This thread got me thinking of replacing the factory 10" with another free-air 10" instead of using an aftermarket box type setup.
I was looking at Crutchfield.com and they have some interesting replacements available.

If the Bose sub is a 1 ohm then I'm looking at this one:
Infinity 102.7w Kappa 10" (http://outlet.crutchfield.com/p_108K1027W/Infinity-102-7w.html?cc=02&tp=13722) 1 or 4 ohm selectable $162
Its DVC 2 ohm internally wired to give only choices of 1 or 4 ohm
RMS 50 - 350 watts
Peak 1400 watts

If it is a 2 ohm then I'm thinking about this one:
Infinity 100.9w Kappa 10" 2 or 4 ohm selectable $190.
Same specs as 1 ohm version.

However they have a really good price on a Kicker Comp 07C104 $45.00
Its a 4 ohm SVC
RMS 50 - 150 Watts
Peak 300 Watts

But if the Bose stock is
75 watts @ 1 ohm
37.5 watts @ 2 ohm? - most likely not worth it
18.75 watts @ 4 ohm? - def not worth it

or if stock is
75w @ 2 ohm
37.5 @ 4 ohm? - not bad for only $45

Any advice on what would be a good idea?

keelerdr
05-21-10, 11:47 AM
hobbs1,

I don't think there are any full range car speakers that are larger than 6x9, which is why all the places online are listing them as 6x9. If the stock speaker is considerably larger than a 6x9, you may be able to replace it with an 8 inch midbass driver. The 8 incher would be round though and only play mid to low bass. This may not be a problem though since the stock speaker may just of been seeing the low notes anyway.

I haven't checked the wiring diagram for your car but I know that for my 97 deville, the "6x9's" were called subwoofers and only received the low frequencies. There is a crossover built into the stock amp that takes the mids/highs and send them to the doors/dash speakers. This is why when people replace their 6x9's with two or three way speakers, they still only play the low notes :banghead:.

I don't have any experience w/the 8 inch midbass drivers. They are not very common...it is basically an 8 inch "free-air" (meaning no enclosure needed) subwoofer that does not play very low.

If you just want a little more low end, a basic aftermarket 6x9 speaker would work fine. I replaced my stock ones w/a pair of kicker 6x9s on sale for like $95 total. It was a noticable upgrade...until I went w/a JL 10w3 :cool2:

Hope this helps

Okay guys, I thought I was confused before... There is all kinds of conflicting information all over the net. I am trying to replace my speakers. I have a 2001 Deville DTS with a Bose system. Every website I go to lists different speaker sizes.

Can someone tell me what are the speaker sizes, and where is the amp(s) located? I want to pull it all out and replace it with after market. But I want to actually buy the stuff first before I go tearing into my door panels and so on.


Best thing to do is get an Alldata subscription. That will give you the exact speaker specifications for your car.

Guys i have a Seville SLS 03

Factory Front Speakers : 6" - (2 ohms )
Factory Rear Speakers : 5.25" (2 ohms )

Replaced with Sound Ordinance 6x7.5 - fits just fine. ( 4ohms )

The factory amp - is hardly firing these, the front channel speakers are more heard than the others..
What after market amp, would you suggest, or any other ideas..

Cheers

I have found that its a 2ohm and what looks like a shallow mount/free air type but does anybody know how big this thing really is? I'm looking to replace it with an aftermarket sub (Particularly a JL Audio) if I can get one to match size wise.

Anybody take look at this? I'm looking through here and it doesn't seem to be anybody has (other vehicles but not 06 CTS)

I have an 01 Cadillac Seville STS. In my dash there are three 2 inch tweeters. The front doors each have an 8 in sub. The rear doors have 6 in speakers. The rear deck has a 12 in sub.



Dash speakers measure 3.5 ohms
Front door subs measure .5 ohms
Rear doors measure 3.5 ohms
Rear deck sub measured 0 ohms

Unless my meter was acting up which I doubt these are the correct ohm ratings for these speakers/subs.


The dash speakers are in sort of a vented housing which makes it appear bigger and weirdly shaped.

The front door speakers are in sort of a bracket that doesn't really make the speaker appear any bigger.

The rear door speakers were not in any bracket but the plastic panel behind the speaker was in the way of my new speakers and o had to break it to fit them in. Im gonna cut the rest out and use dynomat to reseal it back off.

The rear deck is more obvious without taking anything apart. No bracket or anything that I remember.

I hope this helps some of you. I wish I would of had better directions before I started.

Hello. I bought a 92 Brougham with a standard factory cassette head unit, a dead CDM (amp/tuner), and Polk speakers. I eventually replaced the bad CDM with a working unit, swapped out the cassette/only Head Unit with a Cassette/CD one which I believe is from a later model De Ville/DTS (this head unit is identical to the one offered in the Brougham with the exepinoin being that the five preset EQ buttons labled "A B C D E" are absent, with 2- slider controls, one for bas and the other for Treble. I also replaced the the disitigreated Polk 4x6 fronts with a pair of salvaged Delco ones, as the polks in the rear semed undamaged I left them in. Everything wouked well for a couple of months but now ione of the rear polk 4X9's is dying.

My problem is that I have seveal 6x9 Delco speakers but some are 10-ohm and the others are 4-ohm.
Any advice on which ohm ratting was original in the 92 Brougham? My GM shop manual only gives ohm values for the front speakers, which were offered in 2- different configurations on the 91/92 Brougham and referes to the rear speakers, (set up the same way in both the the base 4 speaker and optional 6 speaker) by 6X9s size.

Do you know it if it was was 10 or 4 ohms rear speakers, that were originally installed at the factory?
