amp install, speaker wiring question

[mtnv900]

I'm getting ready to install a jl m600/6 amp. I'm wondering if everyone has just been cutting into the speaker wiring coming out of the HU or have you been running new wiring to all speakers. I'm not sure were they are splicing the speakers together on the 242 since there is 8 speakers and the HU has 4 outputs.

I popped the pins out of the boat side harness. The Clarion manual has the pin-out. Then I used the pins in the amp. Easy to go back to stock, just pop the pins back into the harness. You can pop the pins out with a small flat-head or nail punch. Can't remember which I used. It takes a little force, but most came out pretty easily.

I may, down the road, re-wire, but I'm happy for now.

I didn't want to do any hacking either - so I found an ISO 16 pin plug - like this:

it's a metra 70-7303

You just use the half that has all the speaker wires on it - and you can remove or just ignore the other half. (I sliced the other half off in the bandsaw). There are other plugs that work - but this is the one I found at my local fry's.

(this works with the polk head unit in the 2016 AR240, if your's is different, you could take photos and head over to a car stereo store and look through their wiring kits to match it up - that's how I found this one).

I decided to install my amp in front of the helm. I ran 4 gauge wire from the batteries, through the engine compartment, and forward along the starboard side. 20' of wire reaches that area nicely.

I cut the speaker wires. Rewiring the speakers is a pain. I used heat shrinkable splicers that I think I got from ACE. I ran my power cables to the amp through the fuel tank compartment and added a 50 amp breaker in the positive power cable.

Your boat has 8 speakers? I did my amp this summer and I pulled the plug containing the speaker wires out of the HU and then cut the speaker wires. I spliced the wires with heat shrinkable splicers and then wired the speaker wires to the amp. I also ran the power cables from the batter across the fuel tank, it was the easiest pathway to the helm. I added a 50amp circuit breaker to the positive power cable.

I bought this to run the power to.

I cut and spliced my stock wiring when I added a six channel amp. Your head unit and wiring may be different but in my 2010 242 Ls, the font channels power the bow speakers and tweeters in the tower and the rear channels power the cockpit and swim deck speakers. The tweeters in the tower are connected to the bow speakers via crossovers under the rear cockpit seats. You will have to do some digging to find where the swim deck speakers are spliced into the cockpit speakers. As I recall I just ran new wiring to the swim deck speakers.

Yamaha added a 400W amp to my HU last year and had to swap out the HU also, they had a custom harness they used, I'll try to find the part number if I can. I have now replaced the tweeters in the tower with JL tower speakers so now I need more juice to power them. I did find out the rear transom speakers were swapped, L&R were opposite. I still need to dig around and find where they come in so I can correct that.

This is FINALLY the EXACT item that I was looking for through all of the stereo threads! I needed the exact same harness from the HU so that I could wire up the AMP speaker outputs to the new Metra 70-7303 harness OUTSIDE the tiny helm area and then just PLUG IN the speaker harness to this new harness. This relieves the installer from having to manipulate speaker wires from inside the helm area. Thank you!
