Here's my setup and the box (boxes) build. However, the subs are at Fi right now being re-coned into D2's. I also plan on changing out a lot of the current equipment.
The car:
Pioneer HU. Not sure what model, but I don't like it:
Rear battery. It's a 90AH marine deep cycle. Don't worry, i've since covered
the terminals:
Not pictured are the four Kenwood coaxials, 0 gauge big three (thank you Skittles for the ground help), and the Clarion 4-channel.
Here's the new equipment:
New HU close up:
Phoenix Gold Octane R 8.0:4:
Two pairs of Cadence CWM comps:
Sub amps. Audiopipe AP1500.1D's will be replacing a pair of Planet Audio VX1400D's. They'll be strapped at 2 ohms:
Hang on. Subs and box build pics in a second.
