Couldn't find many pictures on how to do a clean install and after finding a gem of a thread about LOC's I feel this is a must.

What I'm doing here is install twin MTX 12" subs with a 1000w amp.

1) installing the power cable. Always give yourself plenty of slack with the cable, you dont want to run out of room on either end.
a) find the firewall grommet, using an ice pick make a hole through the rubber. Tape your cable end to end with something striaght, like a long drill bit, apply some lube(I used silicone oil). Push the cable through the grommit. I've seen a few people do this the improper way, doing it this way will ensure no water leaks and no chafing.

b) pull up you door sill trim
at this time you probably want to get your amp remote wire in. You'll have to find another diy on how to remove your stereo. Big time hint: the remote wire is yellow/white with a Bose HU.
back to the door sill, pull up the carpet and run your wires under the already existing set of cables.

c) here's where I have another good trick, now pull up the door seal, exposing the access behind the rear seat trim. Pop out two of the retainer clips.

now you have to get a coat hanger and hop in the trunk, pull down the carpet by the left rear strut. At the very bottom you'll see those cables you saw in the door sill, carefully probe with your hanger till you can grab it from the door side. Dont worry, it should be a slim chance that you could catch leather or a wire, not gonna happen.
From here it's pretty self explanatory, pull the remote and power cable through, install your amp ground wire where ever you can find a good place.

Installing an LOC(Line out converter) to run the sub woofer off the stock Bose stereo.

LOC's cost maybe $15 and can save you some big headaches, especially if you dont want to swap out the HU at this time. You'll be splicing into the rear speaker wires and running these wires to the LOC, I strapped mine to the trunk ceiling. Then simply run RCA wires to the amp, follow your instructions that came with you amp and LOC


At this time you might want to use an ohm meter to make sure everything is properly hooked up, especially if you're using splicing connectors, like I did, sometimes they dont connect.

After your all hooked up, install the power wire to the battery, and tune the amp and LOC to match what you want from your system. Start low and work your way up.

Any downsides if you leave the firewall open? Couldn't poke a hole so I just shoved an opening enough to fit my 4 gauge through it since I knew a 4 gauge wouldn't fit through that covering.

Hey Myxomatosis, any chance you still have those pics and could update the links? I'll archive the page on Archive.org for future reference if you can.
