For those of you who have installed a subwoofer in your car, regardless of trim, how did you go about routing the power wire from the battery to the sub (if it's a powered sub) or the amp? I'm planning on feeding it through the grommet located on the left side of the driver area right behind the trunk latch. Besides removing that first panel along the driver seat, has anyone removed the other piece between the driver and passenger doors, as well as by the back seats and the trunk? If so, how? I haven't been able to figure out a safe/easy/smart way of removing those parts to ensure the wire will sit okay.

Pictures would be much appreciated for this. Thanks!

EDIT: Here are some images of what I'm trying to describe, if that helps:

I can't remember the size I think 15 mm for that middle piece in the second picture and then you pop it out. Most of those you just pull firmly to get them out. I used this video to get to the rear deck off

Ya know, that's funny. I've seen that video around YouTube before in the past, but never realized it also showed how to detach the rear seating. Whoo! Thanks. :D

I removed the driver's seat, driver's lower seatbelt bolt, rear seat cushion, and all trim pieces along the way. The biggest pain was the trim pieces that runs up the side of the rear seat. It was a major pain to get back in place properly.

I'm in the process of installing an amp and sub. Here's what I got so far (limited on time lately): I decided to go a little big for the power cable since I'm installing 2 amps (1000W total RMS). Drilled a new hole in firewall with grommet. Cable will run under carpet along driver side sills, under rear bench, into distribution block.

I just tested removal of the back seats, and that wasn't too much of a pain, but the trim by the rear seats seemed pretty easy to take off and put back together... that's leading me to planning on removing the trim by the door, the seatbelt, and the rear seats. I'll probably snap pictures as I remove each section so I have resources in case something God-awful happens.

I don't intend on drilling any holes for any of it. I'll use the grommet right behind the hood release mold, and feed it through the paneling trim on the driver's side to the trunk. Based on the way I plan to set this up, I would think installation could be done in about 1-2 hours by myself (maybe have my dad help feed the power wire through the grommet, that's a little tricky).

I tried to go through the grommet for the hood release cable like some other people did in a previous thread on here. But I can sure tell you, there is no way a 4 gauge wire will go through. That's for sure. I ended up just drilling a hole right above that one and ran it through there. I couldn't find and my other grommet close that I could use. There was a plug closer to the door but you can't feed the power wire towards the engine bay through that hole.

I'm gonna be using 8 gauge, which I believe is recommended for the sub I'm installing (P300-10), and that should work fine. I've been doing endless research to make sure everything I've ordered will work for the way I want to hook this system up.

8 gauge will probably be fine. Not sure what Rockford recommends. My amp required 4 gauge so that's what I ran. There is a thread in here somewhere about it and I ran the power wire the same place they did. There is no need to take seats out unless you want to run it a different route to the back

I ran my previous wiring setup underneath the seats, worked great for me. Probably gonna do the same this time around. Just a matter of loosening a bolt and removing the clamps. But, we all have our ways, right? ;)

I just took the door sills off and ran the cable there. That was the easiest part
That's exactly what I'll be doing. I'm thinking of also taking off the trim leading to the trunk next to the rear seats. Between feeding through the grommet and routing in the sill areas, that'll be the longest process.

Taking the plastic off at the back is fairly easy and it's easy to run the cable. The only part I didn't like about that is the cable comes out in the top part of the trunk inside.
