-Wanted a bit more bass
-Didn't want a box eating up cargo space
-Not looking for spl numbers
Subwoofer: Dayton Audio 12" low profile 4ohm DVC
Amp: Sound Ordinance M350-1
Install kit: Audtek Electronics AWK8
I was only going to use one sub, so I went with the 12". However, I THINK you can fit two 10" subs in that space and keep the cargo tray (tray needed to act like a box).
Keep in mind that I KEPT the stock cargo tray. however, I may need to fab something up so it seals the subwoofer better, as the air passing around the sides is hurting performance. I'll likely end up just using weatherstripping around the entire edge of the cargo tray.
UPDATE: Used some rubber foam weatherstripping to "seal" the tray to the underside of the cargo cover. Cover still sits flush with the floor, so that's good. Also, the Lloyd carpet may I had on top of it was sealing the face of the sub a bit too much, which was causing this flutter/rattling sound that ended up being the mat itself. Removed the may from covering the sub and everything is perfect now. AutoEQ on my Pioneer head unit will automatically adjust the EQ settings for all the speakers as well as the sub, set crossover points, and time delays. The biggest thing is setting the EQ and time delays. System sounds amazing now!
The sub box packaging can be used as a nice template to figure out where you want to cut your hole.
Once a good location was found, I used another piece of cardboard to center the hole I was going to drill for my circle cutter tool. (Hint: the Black & Decker RTX is more powerful than the dremel, and has a threaded collar so it'll fit in all the dremel accessories).
Not the best cut, but the best I could do w/o *real* tools. Sanded the inner edges smoother. Nobody will see this anyways, since I'll have a carpeted mat on top of it.
Pic of where I mounted the amp. Everything fits with the cargo tray (see below).
Amp power wiring. I used less than 2' of each cable, and the fuse tucks nicely under the battery holder bar.
Had to trim the factory box slightly in order to make clearance for the cables. Turn-on and RCAs were also routed through this same hole, which I ahd to cut even deeper to fit the extra wires.
Sounds good so far, but I can't really turn it up too much yet. Need to seal that cargo tray better or else all the air moving past it causes all sorts of flutter/vibration sounds. Running infinite baffle (tray removed) doesn't work too well either, as these subs aren't really made for that.
