This was my first time ever messing around with a Jeep. A neighbor of mine the other week was having problems with his subs and what was going on was the gain was wide open. So I pulled out the DMM and my test tone cd and set it right for him. Now him and his buddy came to me to help them put systems in their new cars they just picked up. Jeeps seem to be built pretty well. Everything was well sealed up and secure which made running wires a pain. But its in there and done. He doesn't have anything special, just a couple off brand 12s with a matching amp in a ported enclosure. It gets pretty loud though and he's happy. Said he'd give me 30 bucks for helping him out, so that's cool.
I can take a few pics next time I see him. His g/f heard the system and was really impressed. She wants it to sound "good" and I asked her what she meant by "good". They've got an older Pioneer deck now running stock speakers. I told her she can get a newer HU with pre-outs, get a decent 4 channel or even 2 channel amp and focus on a nice front stage. Her b/f, the guy I helped, wants it to be slamming. I told him with the room he has he could do a single 18" HDC3 or Fi Q on 1k - 1.5k rms and it'd be rediculous. I looked at the stock alt on it and its already got 4 guage wire stock for the grounds. Of course 1/0 guage is better, but for stock I was surprised. So we'll see what they decide to do.
jeeps get loud as fvk. i had 3 15's in my old one with my re12.1 amp was doing mid 140's around 35hz. where did you run the wire? thru the door or the boot in the firewall? mine was pretty easy except running the rcas cuz the back seat lever thing was broke so it was a pain trying to run them underneath of it.
We ended up having to run the wire through the driver side because there was a huge fuse box in the way on the passenger side. I used the groomet that connects from the door to the frame to get the power wire inside the jeep. I fished the wire with a coat hanger from under the hood through a tiny hole I found in the firewall to reach the door jam. I've installed a good amount of cars and most have been straight forward. The jeep though took a little thinking in a couple spots.
