Possibly THE worst amplifier/battery wiring I've seen in a car!
 
This is running TWO sundown 2500's, with the "ability" to switch between 12, or 16volts.

Behind the right seat, you have a 12volt battery, connected to a (maybe) 200amp switch, via 4ga cable.
The output from that switch is then connected to the fuse block via a 0ga cable, the amps are then connected to the fuses, 0ga to each amp.

The ground to the amps appears to be 4ga, that runs to the back of the car somewhere, rather than to the batteries?

Behind the left seat, two 8volt batteries in series, once again, connected to a 200amp switch, with a single 0ga cable running to the 750amps worth of fuses.
Then there's the 8ga cable to the anderson plug, unfused, running through sheet metal, with no grommet?

Also, we have a copper bus bar, about 1cm from shorting out to the metal frame, and none of the batteries are secured...

Plus, there's two 0ga cables, running from the two 8v batteries, back UNDER the copper bar, so if the insulation wears through, the batteries will be directly shorted out...

Of course, the fuses are bad too.... bits hacked off the ends because the terminals didn't fit, and terminals sitting ontop of the fuses so they aren't flat on the "bus bars"

I'm posting this basically to say, PLEASE DON'T DO THIS IN YOUR OWN CAR!

The guy seems to be proud of his work too?

People have pointed out the issues, but he doesn't seem interested, generally he'll just call people "haters" if they don't like what he's done...

Amps are only wired at 1ohm each, but there could still potentially be 200-250amps required by each amp!

I don't know how the law works in your area but if you do ANYTHING to that system and the problems with the installation cause a fire, you may be setting yourself up for a lawsuit. He could claim that you were supposed to fix problems that you found.

I'd suggest slitting a piece of fuel line (or some similar heavy hose) and placing it on the angle stock near that bussbar.

What are the fuses for in this installation?

Are there fuses on the batteries?

The fuses can't possibly protect the amps. If one amp fails (shorted outputs), it essentially has to blow 750 amps worth of fuses. He needs to break those to two circuits with one fuse per amp.

I dunno man, at least that isn't installed in a car!

Impressive.

I like his terminals on the custom made fuse block.... Some copper pipe, with the end hammered flat!
