Seems legit

The following review is for BAK44BL, which is a part of the bundle you are viewing.

My first time using CCA wire. I was pleased to see the amount of copper in the power and ground wi hires. Quality fuse block. The RCA patch cords are awesome being bundled together. Made installation that much easier.

Not the best, but Good.

The following review is for BAK44BL, which is a part of the bundle you are viewing.

This is an ok kit. Came with everything that Is described. The RCA plugs ARE NOT gold plated.
The remote wire is very thin. Speaker wire is decent but not the best. You get what you pay for.
Overall a good kit ... not the best quality ... alright for the price paid.

The following review is for BAK44BL, which is a part of the bundle you are viewing.

Heavy duty, rugged, works very well. Would recommend to anyone looking for budget friendly wiring. However be advised if you run a stock head unit you'll need a line out converter.
