had a nice little weekend project to install amp and subs using the stock radio... and took pics along the way...

Image


where i went through the firewall
Image

Image

Image

Image

Image


an easy way to feed the wires through tight places with a wire coat hanger haha
Image

Image

Image


took the dremel and made a spot for the ground...
Image

Image


as for the control wire i tapped into the cigarette lighter power so the amp comes on with the car
Image


and i added a kill switch for when my daughters in the car and ran them to the cubby beside the steering wheel
Image

Image


as for the audio signal i bought a line output converter and spliced into the left and right rear speaker wires comin from the stock amp
Image


now i didnt want to deal with vibrating from the load floor so i left it out and built my own floor... also so i could mount my subs to the floor with out drilling through the jeep so they wont move.

and the final product! looks and sounds amazing!!!!

Looks good buddy, I did a similar install with mine the other day but mounted the amp in the tool tray. Gotta say this though. CLEAN THAT ENGINE BAY! LOL.

i would place the subs facing back, they will sound alot better and louder

That's not necessarily true, given that bass frequencies are non-directional. However, that being said, for any given space (especially an enclosed one), there is an optimal placement (different per each sub/enclosure/cabin) for the best listening experience.

If you like the way they sound while facing up, keep them that way, it looks tight too.:thumbsup:

Now as far as tapping into the speaker wires coming from the amp, i have not taken the trim off back there to look at the amp but what i want to know is which color wires did you tap into and also how did you know which one is which. Does it say or did you look at the rear door speakers and see which wire color went to each one? Also which line out converter did you use? Is it a high level output or rca output?

I'll answer for you as I just did this last weekend. Refer to the wiring diagram here: http://wkjeeps.com/wk_audio_pinouts.htm . Be sure to tap the AMPLIFIED WIRES.

Note that the only full range speakers (if you have the factory BA system) are the rear door speakers, so you'll want to tap those to get the best use from your LOC.

As for LOC's, everyone has their own opinion, but I personally went with the PAC SOEM-T, and it was plug & chug, super easy. (converts speaker level to RCA line level)

Also, a product which I notice that no one ever mentions, but make life easier, especially due to the cramped space and tight harnesses are these (probably saved me a bunch of time, not to mention EASILY removable and they don't practically split your wires:

i dont know if you've gone back at all, but please please please put some kind of plastic or rubber grommet in the firewall where your power wire is going through. The last thing you want it to have that wire rub through the insulation and ground out on your firewall. Bad bad things happen, seen it first hand from other shops.

Also, split loom that power wire under the hood, it'l keep it from melting from the heat of your engine on long trips and such.

Easiest place is the cigarette lighter. Snap out the bezel and pop a posi-tap on there. You can run the cable easily from there under the pop down panel beneath the steering wheel to the floorplate sills, where you can run to the amp in the rear.

I also wired in a switch in-line for mine so I could turn the sub on/off at will. Seems to really help with cold starts in the winter for that amp to not suck out all the extra energy.

Looks like a decent build. I'm more of a SQ guy, hence my choice of a more subdued system. I also found it quite interesting that you focused on the vibrations of the other parts of your car more than the subs themselves (which is exactly the opposite of what I focus on). :rolleyes: That being said, looks like you got a decently clean install.

Maybe I'm paranoid, but I'm glad that I put my amp underneath the floor in the cargo/tool space. Security covers scream I have stuff to steal, come get it and I don't think I'd ever put all that equipment in the back of my Jeep, unless you have a nice security system too.

If so, which type do you have? (thinking about installing one soon).:thumbsup:

^ yea. Agreed. My box is bolted to the floor and the my 4 channel is in the floor like yours. My sub amp is behind the panel in the passenger side where the satellite receiver used to be.

Quick story, last year a hurricane came by and everybody had their cars in the barracks parking garage. At some point some assholes swept buy and smashed the windows and grabbed every touch screen they saw. I've got roughly $2k in HQ stuff and mine didn't get broken into because it looks like a generic alpine single din deck. It's actually the hifi CDA-117. Everything else looks factory. Idiots.

Thankfully, the criminal population are typically stupid, and only take what's in plain sight, which is why I opted for the cargo area amp.

If you're unfamiliar with my setup click the link in my sig. ;)
That's a pretty sick setup, mine is much more generic, and I'm still using the standard REC unit with a LOC. I am however considering amping the Boston SE's. Unfortunately, since I like my REC, I'd have to use the outputs from the stock amp (to avoid messing with CANBUS), wire over to the other amp, and then back to the standard speaker wiring loom (to avoid rewiring the whole whip). Too much of a PITA methinks.:mad:

LOL I'm glad I took my time and randomly got it right the first time around. I should've taken pics and done a build thread, but I didn't really have a buddy helping and I was too lazy to take pics. I'm just glad it's working like a champ. The only weak part is my $3 walmart light up switch which has already had the light fail. POS Made in China...and I'm too lazy to return it for an exchange...
 
#28 ·
Yea. I installed the new deck and it didn't turn on. I also reinstalled the REC and it too didn't turn on. I pretty much reacted like the meme where the dude is like "Ffffffffffuuuuuuuuuuu cccccccc kkkkkkkkk!" because the next day I had to travel 400 miles. It was a VERY quiet and LONG drive.

[shoots self in head]. Man that would SUUUUUCK. Glad you're all up and running now though :)

If you scroll down on that page to the Amplifier Pin-outs, they should match up perfectly...
 
#33 ·
Now that's odd. Just so we're on the same page, you're looking at the amp behind the trim panel in the trunk space right? If you don't have gray wires attached at all to those pinouts, it's possible that you have a different harness (off of a different year Jeep).

I got it figured out I don't know what I was looking at yesterday. One thing though... I tapped my remote into the cig lighter in the cargo area so my amp is always going to be on. With the light on the amp on all the time it's just asking to get stolen so is there anywhere else back there to tap into for the remote? Would another amplified speaker wire work for that or could I use one of the FUSED B+ wires from the C2 stock amp connector? If I ran it from the cig lighter up front I would have put a switch in but it was easier to do it in the cargo area and now I dont have that option.
