I have the Audio Integrations Amp Rack(02-07; retail- $235.28) and Driver's Side Sub Box (05-07; retail- $349.99) for sale. the amp rack has 5 holes drilled into it (4 to mount the amp, 1 for the wires), but they're very cleanly done and aside from that is in perfect condition. The sub box is in great condition as well. I am no longer in need of these items as the WRX is no longer with me (R.I.P.). I am looking for $250 for the pair. If interested, I also have a couple subwoofers, an amp, and the wiring for it all that I can sell for cheap. You can pm me if you want pictures, but I'll put some up today after work.
The link to their website is here if you're not sure what these items are: http://www.audiointegrations.net/page/page/3182186.htm
I will be able to meet you, I'm in the Philly area.
