I've been reading through this section & can't find some answers, so here goes...

What is the wattage to the Bose sub on an 04 CTS? Where exactly is the amp for the sub located? Is it a 1 ohm or 2 ohm sub? Would it be possible to replace the sub with an aftermarket sub & still use the Bose amp? I've looked at a couple different Infinity subs (Kappa Perfect 10DVQ, Kappa 102.7W, & Reference 1052w) & I'm curious if I could just replace the Bose sub with one of those. I'm not after a lot more bass, just a bit. I also found this thread that suggest installing a crossover for the sub & wondered if anyone had tryed this or had any more input. I've already read all the stuff about the basslink & the cleansweep, & I'm not ready to upgrade that much yet, so no one needs to chime in about that stuff.

Dissconnect the sub wires, put on a test tone at 50hz, put a DMM on the negative and postive wires (AC) and square what voltage you get and thats how many watts your getting to the sub (if running at 1 ohm, which you can measure too, if it is 2 ohms, divided your anwser by 2).

Also what would you need a crossover for? Techinically you would only NEED one if put it in a ported box, I would imagine bose has it already crossed at 80hz.

Well I don't know. According to the post I refered to, a crossover would clean up the bass & make it more distinguishable since it's a full range signal running to the sub?

I'm not the Bose expert, ETC97 is. But I know for a fact the sub is not getting full-range....120hz at the very highest.

This is what I was talking about. Yes? No?

Hmm new info to me, like I said Bose ain't my expertise.

But that amazes me, a full-range tweeter. If you send something under like 500khz most tweeters are going to be toast real quick.

Back to the original question, is it possible to replace just the sub without adding another amp? Anyone know the wattage to the sub?

hey sorry for my absence im in class so ill make this quick
the bose sub is a 2 ohm sub
yes you can replace it with a normal aftermarket sub no problem the eq for the system is retained in the amp so a new sub makes no difference, however make sure your sub runs no lower than 2 ohms (or else you risk blowing the amp) and as close to 2 ohms as possible (or else the sub wont be as loud). as for the power im not sure cts's arent my thing im more 92-02 bose systems however if i had to guess no more than 100 watts for sure

So....get a DVC4 sub.

or a single 2 ohm vc sub...
or a dual 1 ohm vc sub...

yea....but dvc4 are ALOT more common than both of those.

tru
just sayin tho im sure he could figure out how to render 4 ohms
bein you had to spell it out tho i figured id list the rest of the options hahaha

i think he should get a 10w3v3 4 ohm version that would be good for his app however they are not ment for free air
kicker is the only co that i kno of that makes a decent free air woofer

I thought their subs arern't anymore? anyways you got access to that tracking # yet it should of been here!

So no one knows the wattage running to the sub?!? Like I mentioned previously, I've found a couple Infinity subs that are 2 ohm, but I don't want to waste my money on one if it's going to be extremely under powered by the factory Bose amp.

egh
lets look at this in terms of this
if its like the bose system in sevilles which had WAY more speakers it was a 425 watt 4.1 bose syste,
my eldordo has a 400 watt 4.0 system
you have a 4.1 system as well
so it def isnt more than 425 watts thats OBVIOUS
now since you have speakers to power and thats 4/5s of the system
about 1/5 id guess is sub power
so my GUESS
complete guess
using logic
would be 425/5=85 watts true power
again ive never worked on a cts nor have axcess to one to actually measure it.

Thanks, that makes sence, except I have more than 5 speakers. Any idea on how to find the total power of the system? Everything I've found on the net just says that the Bose system is an option in the CTS, but doesn't give any specifics. I guess I should just call the dealership & see if they know.

you have more than 5 but they are tweeters
you have 4 main drivers which share feed with the tweets
1/5 of your system is sub so id bet its around 85-100 watts

Ahh, I see. I was under the impression there was a different amp for each speaker, including tweets. Thanks.
