: Sound System Not Working Right, Need Help

recently, my sound system (2 15" Blitz subwoofers with 1000 watt kenwood amp) started shorting out and eventually stopped completely. I took it to my sterio shop and they made me upgrade to a thicker power wire which I should of done when I upgraded from 12 to 15" subwoofers. It worked much better and hit much harder after they replaced the wire, but it is still partially shorting out. the subs will just stop working for a few secs during a song then start again. Does anyone know why they are doing this?

Well, Does your amp go to protect mode everytime it starting to stop? Another thing I would check is the RCA's, they can go bad, Check for the ground, make sure you sand the paint off and insure a good ground. Ground is very important.

Im not sure, im thinking it might be the amp going bad or something. What are RCA's?

o man, you know nothing about stereos i assume?
what it sounds like is your amp is starving for power and goes into protect mode which cuts power internally so it wont short out the circuitry in the amp. what you need is a bigger power wire my friend. what size power and ground wire do you have?

RCA will look like this, http://i47.photobucket.com/albums/f166/thewireman/images.jpg

Unless you have it hooked up with your factory speaker wires. (high frequency connections)

He said he already upgraded the wire.

but I just upgraded to a thicker wire, im sure the sterio shop knows what they are talking about. switching the wire did make it work much better, but it still messes up a little. and I had the 15's with the smaller wire for months before I had any problems. could it be a loose connection or something? or is this a battery problem? don't know the sizes of the wire, but I saw that it was thick.

I don't think there are any RCA connections then. Im not exactly sure how it is wired. I think the system might be connected to the stock subwoofer, and there is a sterio wire under my hood, near the fuse box. I also have the factory sterio and speakers.

doesnt mean they went big enough. They could have gone from 10ga. to 8ga. and not everyone is as honest as we would like them to be unfortunately. sounds kind of like a loose connection possibly, but i still say its not getting enough power.

You have a point, and I agree with you, but I figure the Audio Shop should know better, the correct wire size. But now he is saying that he don't think he has RCA hooked to it. Hmmm..

Cadillac_pimpz, Could you take pictures of your amp hook up, and read the number on the wire? It should say, 8 gauge, 4 gauge, 0 gauge, etc. We need more info. Thanks.

im having the same issue when im really beating my subs, my amp isnt getting enough power and shuts off. im running 4ga from battery to dist block, then 8 ga to mids and highs amp, and to my sub amp, im going to have to run 4ga to the subs amp for now. when i get a new vehicle in the next few months it will be wired with 0ga. that way i have plenty of power lol.

Oh yeah, Thats what I have. With a Cap (I use Batcap) helps even better. I have dual Battery with 200 Amp Alternator to help feed the juice my two amps hooked to my one (yes one) 12" Pioneer Premier sub. Sounds amazing.

Does anybody know where I could get dual alternator setup kit for 1999 Deville? It would help a lot! LOL

so your final guess is that I need bigger wire?

I didn't notice any today, but there have still been problems since I upgraded the wire. I just tooks some pics of the wires.

You were right, it does have RCA connections on the amp, I just never noticed it before.

WOW the pictures helps a lot! Well, you have 4 gauge wire. Your Kenwood handles 1000 watts PEAK right? Is it class D? So it would be 500 watts RMS. That should be big enough for your amp. But do you notice any of your lights dimming when you play at high volumes? A cap will fix it. But if your having problems with your system again, I would try a better, durable RCAs. Because from the picture I've seen, the RCAs are bent pretty good and can wear off. You should give a little room play. Here try this, when playing a CD, jiggle the RCA area and see if stops playing music. If it does, its the RCAs.

yep, 1000 watt amp. Class D? what is being rated by class, the amp? The lights don't dim. Can't play cd's, have the stock cassette radio, but I just use my ipod with a cassette converter which works fine. Although I have a cd changer...not in my car, I wouldn't be able to put it in my trunk anyway would I? I hear that the magnets in the subs destroy cd's.

so it turns out that the problem was that with the new power wire, the subs couldn't handle that much power and got fried. so I bought 2 15" JBL GT150d subwoofers to replace them. Although they are being a little glitchy. they are not starting when I turn my car on, so I will have to restart my car to get them to work.
