okay, i promise this is the last question. I wasn't really asking what i wanted to know very well.

I have listed above what i have in the car right now, but i'll say it again.
Alpine cda-9811 head unit
4 eclipse se8572 5X7 40w rms door speakers
factory amplifier bypassed
2 extra amplifiers as listed above
Basically, I want to be able to listen to music at a good volume without having to turn the bass way down. (I want to hear the bass too) Hopefully, somebody can lead me in the right direction and give me my options? Thanks!
Josh
