I want to install my subs into my 2000 Grand Prix GT. It already has the premium sound system (bose) and I was wondering where the subwoofer in it is located at so that I can splice off of it to attach to my subs that I am installing. If anyone has a diagram of the wiring of the sound system or knows where it is at, that would be great!

the small bose amp isnt going to be able to handle anything more than the small subs/speakers that are already attached to it.

There is no separate sub-woofer. In the Bose system, the rear 6x9's get only bass and low-mid's, and the separate 4" speakers do the rest. The problem is the crossover point is too high for aftermarket subs to handle cleanly, so you'd be best off to use an aftermarket crossover.

Already knew that the amp that is in there wouldn't be able to support my subs. I have a seperate amp to power them, what I am really looking for is the audio RED and BLACK in order to get the audio to the subs.

Also, from above it sounds like I can install them off of the 6x9's but I need a crossover. I have never used one in the past and was wondering if you guys could give me more details on how I would go about finding one and installing it. I used to have an aftermarket head unit and I do not want to lose my HUD or steering wheels controls so I want to stick with the stock.

I'm assuming the small amp that is connected to the two 6x9's has to have a wire that connects from it to them. If this is the case, why can't I just splice off that wire and connect it to the audio in on my amp? It has an internal crossover and I think that this just might be the trick. Am I correct in assuming this will work?

internal amp crossovers aren't that great, but splicing into the 6x9 wires then hooking them to the hi-impedence input terminals on your amp should get you sound.

Would the sound be better if I added an external crossover? And by the high-impedance input on the amp I assume that that is the regular input that is on there, correct? What advantages would adding an external crossover add to this?

Are the bose amps intergrated into the 6 x 9 speakers. If they are connect your subwoofer amp to the high level output from the head unit to the input of the 6 x 9 speakers amps.

if your going to run ur amp and subs off of the 6x9s wires, you best bet is to get a decent Hi-low converter. basically a crossover but i think slightly different... maybe the same thing. it still wont sound quite as good as it would with an after market HU but it will sound WAY better than using the hi level in line on the amp. (internal crossovver). the hi-low converter takes the normal speaker wire, crosses the frequencies and then for the output TO the amp is RCAs. this way u can plug them right into the RCA input on the amp

For the crossover network that you need try looking at partsexpress.com. The company has many different types of crossovers, and the prices are also decent.

The Bose amp is located in the trunk,When you open the trunk you will see a little black metal box hanging down from the top inside..thats it.The amp does not say bose on it.Thats because it is actually a delco part.

I would connect your subwoofer amp to the input of the delco amp. Where are you going to mount your subwoofer amp.

Planning on mounting it along the back of the rear seats inside of the trunk. So let me get this straight....if i connect the input of the subwoofer amp to the imput of the delco amp I should not need a crossover?? Or do I still need to buy that.
If I do not need it then how would I convert that into an RCA connection for the amp?
Also if I do need one what exactly are we talking price-wise here. And can anyone connect me to a link of EXACTLY what I would need so that I can tell what to buy for it?

I would connect it and see how it sounds. Play some music that you are very familiar with and see how it sounds. Then make the call. If you like the way it sounds then don't worry about the crossover. Just make sure the you use the high level input on the sub woofer amplifier.

Ended up just buying the hi-low convertor for about 15 bucks online. After I get it I will post my entire installation with pictures so maybe some others can learn from what I'm going to do.

I have 2 subs hooked up to a different amp I bought the same way, exept I run my subs in parallel to a single channel( I had it bridged but the amp kept shutting off) this is the best way I found that still bumped and didnt shut off the amp. ....

Get a high low converter wire it to the back speaker wires buy a set of RCA's and run them to the amp(most newer amps have built in crossovers) then run the remote and Battery wire and your all set. Mine is the same way and I still have the stock deck. My system is loud and will rattle your chest, maybe not getting full potential doing it this way but its loud enough to P/O neighbors. If you want some pics of how I have mine I can do that for you just shoot me a PM. It cost me crap to hook it up....$15=high low converter, $25=RCA's $6.55=pack of smokes for the install.

The reason for the amp shutting down, is that speaker resistance of the two sub woofers that are connected in parallel is to low for the amp to handle.
