Looks like there are plently of threads for guys running silly sound systems in their mall crawlers, so I thought I'd start one for guys looking for ideas for their rock crawlers. If you have your own setup to contribute feel free to post up.
In my Jeep I've been running the same Sony Xplod Cd player for about 10 years. It has survived being full of water, and lots of banging around over the years. For the last 5 years or so my only speakers were a set of under seat speaker pods I was given for free. They sounded ok, but no bass and overall just meh..
I've been thinking about installing an amp and wake tower speakers for a while after hearing a setup my buddy was running. Simple plan. Ditch the CD deck/receiver (the radio stopped working a while back anyhow and CDs are a PITA to carry on the trail), toss the old speakers, install an amp under the passenger seat, wake tower speakers on the cage, and run my phone or MP3 player direct to the amp for music.
First I found a deal on some Bazooka tubbies so I picked those up for the speakers. For the amp I wanted a marine rated unit and found a 2ch MBQuart amp from sonixelectronix
for ~$60 after adding a warranty. Thats all I needed for parts so this weekend I did the install.
Step 1, remove the old radio and associated wiring
Next I pulled the passenger seat out and added some flat steel to bolt the amp to. I wanted to keep it off the floor and as protected as possible. Initially I had the mount on top of the tubes but I was concerned it would be too close to the bottom of the suspension seat so I dropped it down.
I added a piece of lexan over the amp for a little extra protection in case I get rained on.
I added a switch between the seats to turn the amp on and off. You can also see the phone holder that clamps to the seat mount. All the wiring for the amp and speakers is contained to the cage except the power wire of course.
Speakers are mounted just behind the shock mounts on my cage
and after testing it all out, reinstall the seat. Ready to rock and roll. Since this pic I have covered the visible wires with a section of wire loom. Didn't really need to, it just bugged me a bit.
