Sigh.... yes.
I had to to retain ANY form of room in the trunk. By placing them between the strut towers in the 'back' of the trunk (closest to front of car fyi) I retain a decent amount of room. I had this kind of setup with a previous amp, but because it was much smaller, I did not have to Diagnol them. The new amp (X200.4 on the top side) is roughly 7" LONGER (or wider, whatever you choose) than the previous speaker amp, forcing me to do this particular setup if I was to retain the original trunk space.
The picture is dark, but the culprit may be that because I had an extra....oh, I'd say .25" to work with, the amp is touching the speaker box, as well as the side of the struttower. Although the amp is firmly screwed down to the board, it might be getting vibrations from the box that I tried to avoid with the lip of Silicone adhesive between the board and the amps.
Ohh. and I cleaned up the wires much better, so it doesn't look as horrendous.
