The InstallBay AK01

I purchased this kit because of the price, and figured the fuse block, and accessories are worth the price.

I know the wire is greatly over rated at 0 and 4 gauge. The 0 gauge is more like 3 gauge and the 4 is closer to 8 gauge. The other problem with this kit is that the wire is not true copper, but rather copper coated aluminum wire. Aluminum wire is not as good of a conductor as copper. It's common for cheaper brands to use Aluminum only or Copper coated Aluminum wire in their kits to cut costs. The copper coating acts like a carrier and helps power get from point a to point b since Aluminum is not as good of a conductor on its own. I guess this kit could be worse but should not be sold at a 0 gauge kit.

With that being said; they really shouldn't skimp on the wire size in this kit since it is already impaired by the material that comprises the wire its self.

If you don't know this going into the installation it could be dangerous since the main fuse is over rated for the size and construction of the wire, and could allow the wire to overheat and catch on fire without ever blowing the included 250 amp fuse. If you are going to use this wire I would suggest using nothing higher than a 150 amp fuse.

The RCA cables look good but I have not used them yet to know how they perform.

I won't even get into the speaker or the remote wire...

I wish someone would hold these Chinese companies accountable for the misrepresentation and quality of their products. Putting more plastic on wire does not make it 0 gauge but it does make it a fire hazard!

Bottom line:
This is a good kit if you need 4 and 8 gauge wire. The included accessories like the fuse holders, RCA cables, and distribution blocks are worth the cost of the kit. Change the 250amp fuse to a 150amp and the 100amp fuses to 60amp for safety, and you should be fine.

Also, Sonic Electronics is great and got my items to me smokin fast!

What I wanna know is why would they sell 8 AWG ground wire with 3 AWG power wire.. i swear a bunch of monkeys on scooters came up with this package. as for the remote wire, throw it away in the nearest trash bin. next would be the rca wires, they are pretty decent and get the job done along with the speaker wire. all terminals, blocks etc work good as well. In car audio you always get what you pay for, it doesnt matter how much of a good deal you think your getting. if wiring says "Gauge" and not "AWG" then expect it to be 2-4 gauges smaller.
BOTTOM LINE: this is ok for smaller systems but for over 1000 watts do what I did and save for Kicker or tsunami true 0/1 AWG power and speaker wire.

The quality of the kit was very good. but it is not a 4 gauge or a 1/0 gauge kit, the 1/0 gauge is possibly 2 gauge, and the 4 gauge is more like 8 gauge. So if you had a lower power amp this would be perfect, but for an amp that really needs the real sizes, you'll need to look for a bigger kit.

Good setup but the RCa jacks need to be not as flexible. My prongs broke just from disconnecting them from the amp.

The gauge is not a true 1/0. Although, it does have great insulation which looks like a 1/0 gauge. Works fine and does the job for pushing a 2000 W Mono Block and a 1600W AB Amps.
