I put spacers underneath the feet of all the amps to lift them up off the board about 1/4 inch to help keep them cool.

I put a 2.5 inch fan behind the PCX 2125, and the spacers allow the air to flow underneath the amp:

Switch for the fan, in the panel above the driver's feet:

Thanks guys. Here's some shots of the box construction:

Thanks again. I got some upgrades lined up for this spring.

-New rear speakers. I bought another Diamond Audio HEX 6.5 inch component set identical to what I have up front. Getting rid of those 14 year old MB Quart's in the back now, mounting the Diamond tweets up in the rear pillars.

-PPI QBass knob. Will let me get more bass from the sub than using the sub level in the Alpine head.

-6ft RCA for the bass, so I can run the sub signal through the FRX456 and utilize the subsonic filter.

-On/off switch for  the sub amp. I listen to talk radio frequently, so might as well preserve the life of my alternator by shutting down the sub amp when I can.

-Putting a larger fan behind the sub amp (it gets warm the quickest by far), and moving the smaller fan behind the sub amp now to behind the amp running the fronts (amp in the trunk).

-Making a little panel to go inside the pocket below the head for the amp and fan switches. Already cut the wood and bought the vinyl.

-Upgrading the Big Three, in the middle of that right now.

-Cutting the trunk board and hinging it, so I can get at my spare without having to dismount and move the amp and sub.

-A bit of sound dampening. Got an annoying bass rattle in my rear deck area.
