Usable

The following review is for BAK42BK, which is a part of the bundle you are viewing.

The wiring has done me right so far but the only thing I don't like is the speaker wires. You have to carefully split it so the wire doesn't show. Other than that minor thing everything was great and a great value!

price is right

The following review is for BAK42BK, which is a part of the bundle you are viewing.

the price is right for this setup. the ground wire and the power wire are to big for my amp but i made them fit. better to have to much than not enough so if i upgrade to a larger amp it will be fine.

awesome products

The following review is for BAK42BK, which is a part of the bundle you are viewing.

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.

Poor quality

The following review is for BBIC5, which is a part of the bundle you are viewing.

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.

Ok. not the best kit.

The following review is for BAK42BK, which is a part of the bundle you are viewing.

The eyelet connectors are flimsy and the speaker wire is hard to separate. When it does it exposes some of the copper. Otherwise the kit is ok.

Perfect!

The following review is for BAK42BK, which is a part of the bundle you are viewing.

Was surprised with the quality of the copper and actual size of the wires compared to other cheap brands like Schoshe. Worth every penny.
