I run 2 12inch audiobahn exursions on this amp and it pushes them very well. The size is perfect not to big and fits right unerneath the seat or small space. The best part is it stays pretty cool even after running most the day.

I had ordered a Kicker pk8 amplifier wiring kit and these were part of a package that only Sonic had offered. To put it shortly, one of the jacks was grounding out when I plugged it all the way in the RCA jacks in the headunit. It was causing a lot of doubts in the equipment in my system, but I got down to the root and these were the culprit. I contacted Sonic and they gladly replaced the with a set of StreetWire RCA's that worked just fine when I installed them. Thanks Sonic! But as far as these go, I wouldn't recommend them. Spend a little more and get some better ones.

Bought this kit for my 650 watt rms amp. Not true awg 4 guage, but close.jacket is pretty thick.all wires flexible. Reached under the back seat of my 2008 silverado crew cab. But not a whole lot of slack if your going to a trunk. Fuse is ok... ive seen better and worse. Bottom line, if your on a budget and running 800 rms or under, this will work fine.

Good product , but not enough speaker wire to wire two front door speakers in a scion xb. I guess it would have been enough if I had run one of them with the power wire instead of running on the other side of car, but everybody knows that's a bad idea due to engine noise. You would think they would take that into consideration. Also not a big fan of the square and round speaker wire very hard to separate and strip without exposing bare wire.

After reading reviews and most importantly watching the video Sonic posted with this product, I decided to give it a shot for my Cerwin Vega VPAS-12. The wires are exactly as described, true 4 gauge, not all insulation like the other brands. The fuse block is solid and easy to set up. I was worried it may not fit the VPAS connectors since they mention 8 gauge, but it works and it is holding in no problem.
The only thing I did change was the actual battery and ground terminals, they seemed weak, so i chose something stronger and all is well.
Thanks again Sonic!!
