Rock crawler stereo

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.

I have a couple updates on this setup. First, it works awesome. The tower speakers are plenty loud for me, and sound much better than the stuff I pulled out.

Since the initial post I've done a couple small changes. I installed some wire loom over the exposed wires on the side of the amp. Then to better protect it from water/mud I bent another piece of lexan 90 and vecro'd it to the top of the amp. This is easily removable to access the terminals on the amp. but completely shields the side of the amp from the elements, and really makes it so you can't even tell the amp is there.





That was all done before the first wheeling trip and everything worked well. Just recently I decided to upgrade the cable I was using to connect to the amp. I initially used the headphone to RCA cable and it was fine, but I wanted to charge the phone as well and figured I'd rather just run a single cable to do both. I ordered this cable from Amazon. http://www.amazon.com/iSimple-IS76PR...ywords=IS76PRO The install was simple. I just Velcro'd the base to the top of the amp under the seat. The power and ground were connected to the remote and ground wires on the amp so it switches on and off with the amp.



When it came time to test this install (at 11pm) I found 1 issue with the new cable. It disables volume controls on the phone. I purposely turned all the volume options down low, and suddenly got an extremely loud blast of music in my ear. LOL Tried it one more time thinking I missed the setting on the phone but no dice. This time my wife (who was at the other end of the house) came to the garage to give me disapproving looks. LMAO

To resolve this issue, I had to order an in-line control knob. Not a big deal at all, other than needing it for a Saturday ride (on Thrusday night). Thankfully Amazon Saturday delivery saved me and I got one of these at about 10am to finish the install. http://www.amazon.com/PAC-Remote-Amp...vel+controller

I'll add pics of the additional parts this evening. I was in a bit of a rush and didn't take pics while I finished that up.

Here's the level controller I installed. So far it works great. I also swapped in a waterproof power switch.

The pics are all from facebook and are showing fine for me. Anyone else having trouble seeing them?

The speakers sound great IMO. As long as you have a good spot to mount them it's a great option.
I don't have any detail shots of Jake's stereo. At the time he was running a radio, amp, the tower speakers, and a sub. You can see his speakers mounted in the pic below. I can't remember the brand he got. I'm thinking they were either JL or Fosgate.

Just got a little upgrade for my sound system. Nothing huge, just an 8" 100w powered bazooka tube to get things thumping.

Merry Christmas to me!

Got bored this weekend and worked on the bazooka tube install.

It was really simple to wire this into my existing setup. Power, Ground, and remote, and plugged in the RCAs on the bass tube to the "line out" on the amp.

A quick test in my garage indicates it will sound great in the Jeep, and not really make much of a difference outside the Jeep. That's probably also a result of the tubbies being so loud. I had to turn the gain on the amp down about 20% to balance the bass tube with the other speakers. I still didn't turn it up past 1/2 way and it was plenty loud. I was waiting on the paint to dry on my mount so no finished pics yet. The mount is just 1-1/4" square tube and the bass tube will be held down with a couple lashing straps.

Installed and ready to rock. Just need to bolt the drivers seat back in. Sounds great.

This setup has been working great for almost a year now. The only issue I've had at all was a cheap 30pin extension cable acting up and not charging or playing music. A replacement cheap extension cable got it all working again.

The only change I've made recently was the result of switching from an iphone to an S5. Since there is no adapter to connect the Galaxy to the 30pin cable for charging and music, I picked up a Bluetooth adapter instead.

http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

This connects to the isimple cable and still turns on with the previously installed switch. I ground a notch in my glovebox door so I could run the cable into there (that's where the cable ended already and had an extension from there to the phone mount on my cage), and the Bluetooth adapter is in the glovebox and out of the weather. I've only tested it briefly, but it worked great. This does account for the volume on my phone, and I still have the gain knob between the seats. I'm going to leave it for now, but may remove that and just control the volume from the phone.

Quick update today.

My Jeep is going through a bit of a transformation right now and I finally got to the point of re-mounting the amp. Taking a lesson from what I learned on the original mount, I came up with version 2.0. The amp still mounts in the same location and orientation (upside down under the passenger seat), but I made the mount both removable and hinged. With the previous fixed mount, I had to use a 1/4" drive socket wrench with a screwdriver bit due to the tight clearance. This new setup will make wiring a breeze.

Since these pics, I drilled a couple holes and added 1/4" threaded inserts on the front of the mount. Remove the front 2 bolts and loosen the rear and it hinges up. Remove the rear 2 bolts and the entire mount comes out.
