My audio upgrade/build

I was hoping to upgrade the audio in my daily driver. I had a few components laying around and decided to go for it after hours of research on whether or not it could be done on this vehicle being a hybrid. I had a few goals, sound quality, completely hidden, no permanent modifications, and access to spare tire if need be. The components are a JL Audio 13TW5V3 powered by a JL Audio JX1000 amp with a Tsunami HCap-5 capacitor..




The start of box build. 3/4' mdf


Attached everything with Titebond III and 1.5" screws. Added corner bracing and later box bracing around the seams/joints then sealed with acrylic latex caulk.


Attached the top. Used Bondo on the screw holes. Originally planned on painting. Test fitting everything. Its a tight fit.

Decided later to carpet the box to match interior and help seal sub.


Attached and wired everything up on the box. Added a plug for easy removal if spare is needed.

In car. Goes in and out. A little heavy but it works.



Power/ground hooked up. Plug swivels on a screw to make removal easy. Positive attached to bolt on top of terminal by fuse. Cut plastic cover for clearance. Ground attached to battery between terminal. Drilled hole in battery bracket, attached anl fuse block and grinded bolt down for clearance of battery.


Remote/High Level & Bass control all removable and ran between battery and box. Cut hose and wrapped around wire. There is sharp edges on the battery.


Spliced rear speaker wires, soldered and wrapped with electrical tape.


Found empty space in fuse panel that is switched. Used an add a circuit and a 3 amp fuse. Works good other than noise I am having. Don't think this is the issue as I tried the cig fuse (top left 10amp) and yellow 20amp also. I would prefer to keep on an empty circuit.
