Finally got around to posting a how to on this install. Don't think theres a complete right up on this yet so here goes.

Im taking the system from my old 300zx. My main concern was to maintain the stock look inside the cabin and under the hood while having the ability to remove the box/amp if I need the extra trunk space.

I started by attaching the amp to the back of the sub.

Then dismantle the interior panels. This part is surprisingly easy. Most parts are just pulled of:

Some have this type of clip:

Just pull out the center part with your nail and then it pops off:

Probably the trickiest part is finding a place to run the power cable through the firewall so that you can't see it under the hood. We jacked up the car and found a soft rubber grommet around the steering column hidden by a plastic cover:

Next remove the glove box:

There are written details on how to do this on another post, will edit it in later.

Then the radio, I used BP gift cards to separate the center vents from the microphone and then pull it back towards the rear of the car. These are just clips and good force will pop it loose, just take care not to scratch/bend the plastic, its very soft. Then a couple screws keep the radio in place.

At this point wire in the LOC, the wiring diagram is on another post too so ill post a link soon. There is a nice little spot under the radio on the passenger side thats big enough to hide the LOC (green thing) out of site:

Now the easy part, run the Power and Remote Cable on the driver side and the RCA cable on the passenger side. They should come around behind the rear seats then connect the Amp:

Now you can put all the panels on, clean up and enjoy your enhanced bass :-)

I did this install with my brother, both of us are pretty handy around cars, and it took us about 4 hours. I want to post links and thank those who posted earlier about the glove box and wiring diagram that made the whole install a breeze.

From what I've read on other posts on running the power cable I think the steering column is the best place to run this. It looks really clean and with the battery cover on, the power cable is virtually invisible.

Next post is the finished product...
 
This is the finished product,

My favorite part... under the hood :blush 1:

This is the only visible sign of the power cable, btw the fuse fits in the batter cover, too

This is after the install the cable is under the platic cover around the steering column.

Nice writeup! Excuse me for being a moron but what is LOC (line output connector?)? I presume that's how you integrated the RCA cables to the factory head unit...but for some reason I cannot figure out what LOC stands for :confused:

LOC is a "Line output converter," basically your 100% correct, you splice into the speaker cables and it converts it to RCA.

8 gauge wire, more than enough for my amp (its big for nothing). Here are some pics of the fuse.

are you under your car with just a jack holding it up?

BTW, always use jack stands, safety first :-)

I would have done this in the garage but we were working on the civic. Adjustable shocks, coilovers, camber adjustment, complete bushing kit, front and rear disc brake conversion, non power steering rack and pinion and of course rims. Ready for AutoX.

Its my dad's car and I keep telling him that the MS3 going to whoop it with the A/C on

That's exactly what I was thinking, that is scary!
My neighbors brother died when his pick-up truck fell on him while he was working on it with just a jack.

And what's up with the flip-flops? lol

Thanks for the write up, I just ordered an amp and can't wait to get started but I don't know what head unit to get, I want to retain the blue tooth feature.
 
Should've mounted the amp to the back of the seat so it's not as easy to steal. Now it's sub and amp combo, instead of just the sub.

Get the Pioneer Premier 610BT or the 710BT. They both have bluetooth but the 710BT has a much better display. I got the 510UB, pretty much the same as the 710BT but without the bluetooth, and its a great sounding headunit. Much better then my old Kenwood that I had before. Also has great iPod integration too.

Thanks for the suggestion Ty07allstar. Are you able to use the steering wheel controls with this or any other head unit?

I have a '03 protege but I'm pretty sure they have an adapter for these headunits so you will have the ability to use the steering wheel controls.
