I have a '93 SSE with Kenwood Components in the front and clarion 130Watt 6x9s in the rear which sound great, i also have 2 12" Kicker Comps in a quad-port plexi Bandpass box from my old '91 LE. I'm trying to hook up my 800Watt amp for my subs but it seems like i'm barely getting any power.....when i put them back into my 91 everything works prime. Any suggestions???????

What is poering your subs now? Your amp should be powering your subs, not your radio. If you are not getting any power from the amp in one car, but you are in the other, then I would check all my stteings on the amp to make everything is set perfectly. I got sony amps powering the main speakers in car, but my subs sounded weak until I got a seperate eq to balance out my system the way I wanted it to sound. You also might want to check your amp fuse that goes to your battery (you might have blown it in one car and not the other). YOu might want to get a Cap, I got a 2 farad cap and my needle still dips to the red at full blast.

look into an efficient type of amp like class d'*. if nothing else, make sure you have a upgraded alternator. if the amps aren't power hungry you might be able to get away without upgrading your alternator or getting a extra battery. I also had 2 caps and still would find the red on the battery gauge. I think caps are overrated. Alternators make a bigger difference

What kind of head unit are you using? Do you have another setting for the amp on the radio? If so I would check to see what you have it set at(sub). You have it hook up with RCA jacks Right? It sounds like you don't have your input right. Ley me know what you have it hooked up to.

There were 2 alternators used in the early 90'* Bonnevilles. One was a 105 amp, the other a 140. This might be a factor for you.

Check out your wiring!

If your speaker wires are hooked up correctly on one sub and reversed on the other the speakers will cancel each other out. The result is : almost no bass
