New way to route power cable, Inverter, Amp, Sub all under front seats

Here is a small write up on audio upgrade. I used to do audio when I was a teenager, dare i say 20 years ago. I had absolutely no confidence in my local area car audio dealers and did not want a hack job so I ended up doing all this over the course of 4 days. Sound is infinitely better than stock, but this amp does clip when turned up to 22, you can turn the bass down to eliminate this and turn the remote gain up on the sub to compensate.

4ga battery cable into cabin
Inverter
Audio


I found some instructions on running power into the cab by removing the passenger side dash panel and poking the cable through some expandable foam. I tried this but I do not feel it is safe at all, when running the cable through the foam into the engine compartment/cowl it is surrounded by sheetmetal that can cut into insulation.

I removed the battery in an attempt to remove the battery tray to gain access to another location, removing the battery tray on a 2013 is difficult so scratch that. I discovered a hole when I removed the firewall insulation and this is the best way by far to run power into the cabin.

Feed coat hanger into cabin to pull wire in


4awg power cable


4awg with wire loom for the stock look


Opted for a breaker instead of fuse







Audio:
I opted to stick with the factory head unit to deter theft with the roof off, but installed all new speaker wire to all locations, dynamat the enclosures and stuffed with poly fill, new amp, sub, and inverter all under the front seats.

Another custom seat bracket with pure sine wave inverter, Memphis Audio amp, and fuse block.
I also ran new wire from behind the radio to the high-level input on the amp.
FYI, there is a grounding stud on the tunnel area by each seat.


















Now on to the speakers, not much to be said here other than components in front and coax in rear. After installing the rear speakers I had to seal the perimeter them with silicone, made a big difference.

Great write up!

Going to use this for my Install

Question... What precautions do I need to take when removing the front seats that have side airbags?

Very nice install.

I used to install this stuff too about 20 years ago. I don't trust anyone else messing with my stuff, either. The last car I owned that I let anyone else touch was my GTR and that was only to tune it after I installed the parts

Definitely subscribing to this thread for when I do my install. Might try to play with a fiberglass enclosure this time.

Thanks for the write up! Does the clearance change if you have heated seats?
