Now check the ground first. Then, you'll be spending some time seperating the wires. Depending on how they started, you may change the running path, but the basic idea still stands.

1) Run the power cable [should be atleast 10 gauge, preferably 4 or 8 gauge and with a good solid conector on the battery and fused within 18"] on the passenger side along the door sill. Very easy to do this one, all the bottom panels remove with screws.

2) Run the rca cables under the passenger seat, as far towards the center as you can, unless you want to remove the seat. Again, same basic idea, remove the door sills and lift up the carpet. Working uder the carpet where the seats are is a pain, but it can be done.

3) Run the remote lead and head unit ground if neccessary, under the drivers seat, again as close to the center as you can.

4) Run the speaker wires under the drivers door sill. This will depend on how they wired them. I assume that they ran wires from the amp to behind the head unit where they connect to the origianl wiring. I'd personally replace those wires, as it sounds like you have good taste in audio componets. The rear are very easy, just run a new wire, 12 or 16 gauge wire, from the amp to under the carpet to the rear speaker. That'll help. The fronts are a whole lot harder to replace, but if you have the patience, it can be done.

Now when you get the wires to the rear seats, run the center wires under the rear seat cushions and through the holes where the seat back is connected. Small hands are a plus here. The outside wires can be run the same way but towards the outside or can be run under the plastic finishing along the door frame. I'd avoid that, as those panels break and don't go back together very easily.

Keep all of the wires as short as possible, and don't keep the slack of the wires together.

I bought a lot of my connectors and such from a guy on ebay, but he has a website that has the same deals. www.darvex.com
