So I have finished the install. Here are a few more pics of the progress.



Running the wire for the tower speakers wasn't too bad. As JoeTechie pointed out, I'm using a Speakeron cable to wire up the speakers. The reason I chose this was that it has 8 wires (look to be 14-16 gauge) that terminal in a nice locking plug. Since my tower is completely removable, I didn't want to hard-wire anything in the tower.

First was to make the hole for the plug in the gunwale. I taped it up, drew my outline, and started drilling. I then used a dremmell to finish up the opening.



I then re-taped and marked the mounting screw locations. Then drilled those holes.


I wired up the back of the plug, attached the speaker cable, and used some silicone to ensure they stay put.



I used a cone-shaped dremmell bit to round off the edges and take the gel coat back a bit. This should help prevent any spider cracks from forming.



If I had to do this again, I would have made a wooden backing plate, drilled the mounting holes bigger, and screwed into the wood (much like towers and typically mounted). I did get a few little chips in the gel coat, but they're really small. Learning experience I guess!

I then taped and marked the places in the tower where I had to drill to run the cable. I used a center punch to dimple the holes, and then went to town with a uni-bit. These bits are sweet, they are shaped like a cone, and are great for this type of task.

Since my tower has hinges on both the front and back supports near the top (to fold down), I had to drill 3 holes in all. After drilling, I removed the tape and used a file to smooth the edges down.


Running the cable was fairly easy. This cable has 8 wires with a strong plastic jacket surrounding them. A little soapy water will help the cable slide. I just started feeding the cable from the bottom, slowly pushing it up the support. To pull the cable out of the holes, I used a long pair of needle-nose pliers.

When all was done, you could barely notice the cable.



I'm running a pair of AudioFormz twisted enclosures with Polk MOMO MMC650 speakers. These are 2-way speakers with external crossovers. They are marine certified, so they should last.



On to the sub box. I'm using a JL Audio 10W3v2, dual 4Ohm sub. These things are amazing! I'll never use another brand. I decided to follow the recommended specs from the manufacture, so my box was 18" x 11" x 9". I used 3/4" MDF to construct the box.

One tip I have is when drilling for the screws, use a large bit in reverse to recess the top of the hole a bit. This will help the screws sink in flush with the MDF.


Also, brace the box as much as possible. And use tons of glue to seal the box. These two things can make a huge difference.



This system cranks. The sub is ridiculous. I'm running the Polk MOMO MMC650's all around, and they sound great. I'm still dialing in the amp gains and crossovers, and doing some finishing work. I'll have a few more pictures to come of the finished amp rack and sub enclosure.
