Real nice 8 guage wiring kit

By brandon on January 6, 2011

Nice kit.

Used this kit on a 2007 Mustang. Solid kit for amp install. Would buy it again.

Good quality

I got this wiring kit from B*stB*y a few years ago and its a great kit. Everything is included and its of good quality. The wiring seems to be of correct gauge, and the only problem I've had is a blown fuse and the need to upgrade due to a system upgrade. If you need an 8 gauge amp kit, this is a great kit. Although there are probably better deals here on Sonic than this specific kit.

Wiring kit is awesome.

This wiring kit is great, everything you need in one nice package. Works great with my 1000 watt rockford punch amp to power m 2 12" subs. and at the price you can't go wrong!

Kit is all high quality, and made installation a breeze. It was my first time installing car audio and this kit makes it very easy.

Great 8 gauge kit

True to spec wire its thick and high quality. One thing I really like about it is it already came with the ring connectors and heat shrink on the wire. very satisfied. sonic has the best prices around too.

Excellent kit

Great kit. Wired my 200W amp and sub in no time and sounds great. You don't need anything else. High quality wires. Very flexible. Can't beat it for the price for certified copper and not CCA.

Better than your average 8-gauge kit!

Rockford always delivers with the best value for money and their amp install kits are no different! This is a true 8-gauge kit unlike some of the other kits on the market. A+ rockford!

The BEST 8 awg around

I would highly recommend this kit because not only is it true to spec quality wire, but in this kit comes everything you need to get started. Most people overlook wiring when purchasing systems, but this wire will keep you running safe and cool. It handles up to 500 rms!
