so ive got my car audio set up exactly the way i want it. i have this sub Pioneer TS-W301R Reviews
This amp
Dual XPA4100 - amplifier Car amplifier reviews - CNET Reviews
And this stereo
Sony Xplod CDX-GT630UI Car CD changer reviews - CNET Reviews
and when i turn up the volume on the stereo it seems to get quieter on the stereo not that the music is overpowering the bass. i just didnt want to spend a lot of money troubleshooting so if you know, it would be great.
