"The problem is the sound quality sucks! It sounds like a cheap $40 boombox from Walmart with very little bass."

Your amplifier should be powering a sub-woofer. My Alpine does and my 2000 C2 rocks with the best of them. I have a bazooka sub-woofer (old time solution) planted behind the rear fold down jump seats. Mine also has the 6 speaker locations, 2 on the dash, 2 in the front doors and 2 in the back seats Plus the bazooka. The original owner added the Alpine sound system and Alpine navigation back in 2000. The navigation sucks but the sound is pretty good.
