I put in some new front door speakers today on my 2000 silverado 1500 series ext cab and what a difference over factory! They sound nice up to a point and then become extremely distorted and it sounds like someone is clapping in your ears during the loud bass notes. Now, they are Alpine SPR-17S and are rated for 110 watts RMS each, I'm currently pushing 100 watts RMS to each with a Pioneer GM-X374 amplifier in 2 channel bridged mode. I definitely should not be overpowering them so what the crap is going on?! I'm pulling the backseat off tomorrow to mess with the amp and hopefully fix this. I assume things to play with are gain controls and the passover? I figure since within a week or two I wll have some subs in that I should turn on the High Frequency Filter (only send higher frequencies to door) to keep the door speakers from trying to hit those low notes and blow themselves to poo?
