- 1984 Bright Red Coupe
After some advise of this forum I kicked the Bose to the curb. I have replaced all factory locations with Infinity speakers. Now I want a little more bass. I cannot find a sub box customized for the c4. Plenty of C5 boxes available. Other than having a local shop build one, $500 plus I am not able to find another solution. I would also like to see if anyone has customized a premade box. And as always I would like to see some pix of customized audio systems.
