I wired in a power switch as there are times I will use the system without the tailgate down (for example when camping and I have my hitch in). I also, just ran a standard amp wiring kit along the undercarriage rather than cutting into or modifying my 7pin connection. The 10 Gauge wire was much cheaper than buying the $90 pigtail.

Thats all great and all, but just curious, why go this route vs getting the KICKER system thats avail specifically for our tailgates?

I only ask this because you still only have 2 speakers versus the 4 speaker set up which is posted in OP.

Kicker system ~$600

This ~$150

I am an audio engineer and trust me, you only want the 2 speakers.  One for the left channel and one for the right.  When you put 2 speakers playing the same thing next to each other like that, they actually interfere with one another.  The science of it is complicated but its called comb filtering.  Feel free to go down that rabbit hole.  

The basic principle is you put a speaker where you want sound to be.  If you want more volume, use more power to drive that speaker (as long as it can handle it) and not more speakers.

Well that explains it  lol

Any pics of how you wired everything up?

I don't, i just followed the standard wiring diagram that came in the box. The amp wires were ran thru the tailgate, above the spare tire, then along the chasis, up along the firewall under the hood and to the battery. I used zip ties to secure the wiring .

Not to mention the kicker system sucks

What sucks about?

[wade_660]

The best analogy I can come up with is that it sounds about like playing music through your cell phone speakers vs using Bluetooth through a real radio. You really should listen to one before you buy.

Sorry to OP about the tangent, but had to ask...

 

This is a bit extreme, but some wakeboat owners go nuts with multiple tower speakers.  Would they have an issue with comb filtering?

This looks so cool, can you provide the 3d print files either through thingiverse or yeggi?

Another for the STL if you don't mind sharing!

I am trying a slightly different approach on this. I have a 3D printer, so I have designed replacement panels along with panels that have recesses for the bluetooth controller and an aux port.

Once I get the marine speakers in, I will print panels that have mounts for them as well.

Actually do you have your 3d model or cad file or whatever you used? I'd like to modify the speaker one to use bigger speakers

I posted my thingiverse links where you can download the stl files.

[Rob Simkow]

Was anyone able to modify the 3d print files to allow for larger than 4" speakers?  I'm also very interested!

Did you mount the amplifier inside the tailgate? If so, how did you mount it?
