Custom B7 Avant subwoofer enclosure and grill, the enclosure is fiberglass and fits a 10" sub, 0.5cf sealed space. I run a sub with 5" depth, you can likely get away with 5.5" but more than that and it won't fit. The enclosure fits behind the door on the right hand side and the grill replaces the door. The grill is currently tan, but you can easily peel off the carpet and replace with black if needed.





The box is raw fiberglass, but is solid as a rock and hidden behind the grill anyway so I never bothered smoothing it too much or painting it.

Amplifiers:

1 x JBL MS-A5001, great little subwoofer amp and underrated at 500W, actual tested at 700W RMS
1 x JBL MS-A1004, 4 channels at 100W per channel, also underrated actual tested around 120W per channel
1 x Alpine MRV-F345, old school V12 amp, 4x75W

I have the boxes and manuals for the JBL amps, the Alpine box was thrown out long ago. Amplifiers are all currently installed in the car and working fine, I can try to grab some pictures later but may be tough since they are hidden behind various panels.
