[QUOTE="loudenuff, post: 8511157, member: 664608"] Well for one that's generally a lot of power on a stock electrical system, especially on an older commuter like that. Could be overheated or low voltage, they could be cutting back on power to prevent damage to the amp/woofers. Trunk lid isn't that great of grounding. Try cleaning off the paint around your strut towers (the things in the back corners of your trunk with large lock nuts on them). 2 you should have a local autozone or shop of that nature test your battery output under load (when you have your speakers playing at listening volume with a bassy song. Or you can do it yourself with a DNM if you know how to. Try having a load test first since most shops do it free. If it's low voltage you might want to do a big 3 upgrade or even replacing your battery with an agm. Stock alt might be too low amp to support the power draw. Also make sure your amp wiring is sufficient to support that much power, gauge and fuse. Give that grounding location a try as well, I use to ground to thin metal on my car and had problems when using bigger amps. Good luck to you [/QUOTE]
