i have a 15 inch q power sub and a kenwood 800 watt amp. i also have the pioneer 5 way 6x9 and the regular 4 inch door speakers and a pioneer 7700. when i have the volume about have way up and i turn my woofer up, the woofer goes out but the amp stays on. at night it seems to be dimming my lights alot more because i just hooked up my door speakers about 2 weeks ago but before it was cool. and also when i press my brakes sometimes my woofer cuts off. can someone help? thanks in advance guy.
