impressed

The following review is for BAK42, which is a part of the bundle you are viewing.

I ordered this kit because it was fairly cheap but I have to say in very impressed with the quality of the wire as well as the thickness of the insulation. It was much thicker than I had anticipated and was pleasantly surprised.

Not bad

The following review is for BAK42, which is a part of the bundle you are viewing.

It was pretty nice the wire was a little bigger than i thought (wire is about as fat as a sharpie marker just the wire not the insulation), the grommet that came with it was way to big for the wire so i didn't use it the fuse seems ok the connectors are good didn't have trouble crimping. I had to drill out the ring terminals a little but wasn't bad; wire insulation kind of soft and easy to puncture.

not enough

The following review is for BAK42, which is a part of the bundle you are viewing.

first the terminals are too small for the gauge wire for the power and ground and fuse. a lot of the things that came with the kit didn't seem to have a place with the wires e.g. butt end connectors, cable terminals, all were too small for gauge wire included. im having to run out and buy pieces from my local radioshack. the remote wire has nothing to even connect to my head unit making have to go out and buy more materials to complete my install.

Ok product

The following review is for BAK42, which is a part of the bundle you are viewing.

The product works. Not the best quality though. The cables are pretty lightweight. If I did it again I would spend a little more money and get a higher quality cable.
