Good! The amp is on. Next places to troubleshoot are the source and the gain.

It sounds like the source is OK, but your gain/bass boost/low-pass and subsonic filters may not be set properly.
1) If you have bass boost, turn it off. If you have a low-pass set it to the highest value. If you have a subsonic filter, set it to 0 Hz (or as low as it goes). Set your gain as low as it goes.
2) Play music that has consistent bass. Lil Jon or Young Jeezy are good choices. If you have access to noise sources (pink or white, -6 dB) you can tune the system with them too.
3) Turn up the headunit to the loudest volume that you would listen to, with the front door and dash speakers.
4) Slowly turn up the gain and listen to the subwoofer. When you hear slight distortion, turn it back down just a bit.
5) If you want to use a low-pass and subsonic filter, set those to your liking (120 Hz and 30 Hz should be a fine combination in this car) and repeat Step 4.
6) If you want to use bass boost, set the frequency and level... then turn down the gain until distortion is no longer heard.
Question: Which "amp-in-sub" setup do you have?
