Current Stereo Progress

I”m following this plan here. But over a 1+ year period. I’m down to the step where I have all the wires, all hooked up, and everything is working.

But I’m still building the AMP RACK out of wood. I have my wood piece and I’ve cut it with a jigg saw (but f-ed up 2 cuts) and now i’m waiting on some CARPET / GLUE to arrive from Amazon to carpet it. Then I can mount the (2) Amps and Capacitor to the board and mount the board.

Follow the progress below.

In 2005 or so I got this head unit but never followed through and upgraded the stereo. Instead I focused on speed upgrades. Now I’ve caught up with the items that should have been purchased back then using ebay. Here’s the build:

Next I plan on moving the tweeters to the sail panels like here.



Here’s previous work


2005 Alipine Subwoofer Mono Amplifier

4 Channel Amp: Alpine


Door Speakers

After the new tweeters and speakers and sound vibration stuff.

Bought a speaker ring install kit.

Trunk vibration stuff

Took the Stock Subaru subwoofer, and cut a bigger hole then put in a 6.5 mid-bass.

Used a dermal cutting disc (sparks went flying). It’s wired directly into the stereo wiring harness. I then bought a line out device and plugged in two RCA which then go to the mono amp (sub). PAC SNI-35 Variable LOC Line Out Converter

This is the tiny PREMIUM stereo upgrade subwoofer for the stereo in 2003. haha. It’s TINY. I shouldn’t have used it for 16 years. haha. On top of that, my stereo wasn’t configured correctly for it, I discovered. Once I changed one option, it sounded way better, even with this POS.



Here’s the new 6.5 after it was fit in. I then ordered a 6.5 grill cover from China which took a month to get there. After it’s all together

it’s really tight against the passenger seat, under it.

It stuck way out of the old box.

I bought two spacers that filled in the gap there.


Here’s the thing  with the grill cover that came later. RCA go into the line whateveritsscalled. It’s under the passenger seat and when I pump it up you can feel it. Keep in mind this isn’t the 12″ sub in the back. This is a 6.5 midbass.



0 gauge to 4 gauge in the trunk.

Bought a KnuKoncetpz Battery Terminal where I can plug the wires right into it, then the old terminal into the new terminal. To the right you see where I put my 0 gauge 200 AMP fuse.



Power cable goes through firewall near the clutch pedal and left.

RCA cables go down the right side of the car and under the back seat (as shown). Other side of the back seat has the blue 0 gauge power wire and a

back up camera wire. Then the seat was put back on.


Ran 1 power cable, 3 rca cables, back up camera cable, 3 ground wires all through the middle flip down back seat armrest.

Here’s a sample of the amp rack i’m building. First you start with cardboard and make a design. Then make it in wood.

Wood cut (wrongly)



Sub. It doesn’t fit the trunk specialized but it was only $100 on facebook marketplace.


Speaker Grill but the cover (even though it’s by Alpine) sucks and doesn’t stay on.
