BAK 82

The following review is for BAK82, which is a part of the bundle you are viewing.

Nice package, quality wire but could more end connectors for the larger wire.

Good product

The following review is for BAK82, which is a part of the bundle you are viewing.

It's exactly what you need for your car amp installation. I bought this kit with Kenwood KAC-1502S amp for 75 bucks. Good deal from Sonic Electronix.

Great kit for the cost

The following review is for BAK82, which is a part of the bundle you are viewing.

Very nice kit for $18.
Wire seems adequately thick. Good quality fuse (not AGU) and fuse holder. RCA's feel durable. Decent assortment of accessories. All together a solid budget kit IMO.

Don't know what the other guy is talking about.

The following review is for BAK82, which is a part of the bundle you are viewing.

This kit was awesome and included with my package that I bought. In comparison to others for the same price, there is simply not a comparison and the other review is just wrong on so many levels I felt compelled to write this.

The reality is there are a lot of real shoddy amp kits and wire as a whole being used in car audio in terms of cheap amp kits that have over-insulating wires and fake gauge ratings, huge amounts of aluminum, lousy RCA cables, fuse holders and other accessories. BUT and a BIG BUT, this kit excels in those areas where others fall flat on their face. I have bought a few inexpensive 8 gauge kits in my day and XScorpion, Raptor, Install Bay and others haven't even given me the 8 gauge of wire that I paid for, and in some cases gave me wire that heated up to a dangerous level due to the actual make up of the wire.

I also literally laughed when I see that the other reviewer was intending to use spade terminals to connect his amp power and ground wire... It is for the SPEAKER wire knucklehead :-). I am an installer and the smaller accessories work just fine when you use them correctly. Most amps will still work with them when used with the speaker wire. Of course one can be used for the remote wire connection to the amp and the other end with the butt connector being used to connect to the stereo. The funny thing is, if you do not need them, who cares? It is like ordering this kit for a compact car or single cab pickup. You will not use all of the power wire for these applications, so do you complain that the manufacturer gave you extra wire? That just made me laugh.

Now, onto the other accessories. The AFS fuse and holder that are included are so far superior to others in this price range and the amount of copper (albeit CCA) is much better than others in the price range. Lastly, the RCAs included are awesome for the price. I cannot find ANYTHING to complain about here for $21.99.

All in all, you will not get a better value for the money.

Good product for the price

The following review is for BAK82, which is a part of the bundle you are viewing.

Good wiring package, good quality fuse holder and wires, I would like more connectors on it and maybe some tube for the power wire, but overall is a good kit.

Good Purchase

The following review is for BAK82, which is a part of the bundle you are viewing.

I used this kit to install a 2 channel Boss amp. The quality of the pieces in this kit is five stars, but I'm giving it 4 because it is my belief that to do a clean install you need (4) 8 gauge terminals (one at the batt, one at the amp, one at ground, one at the amp), not just two. I had to spend an extra six bucks at Orchard for the extra terminals, but since the cost of the kit here at Sonic was only $20 at the time, it was still a good deal.

Good kit

The following review is for BAK82, which is a part of the bundle you are viewing.

Good kit for basic setups. Using it right now in my mothers system powering a simple 12. Could handle more if needed.

Pros: Handles power, Wires are HQ, More copper than rubber, Wires are good length, Fuse is HQ, Comes with lots of ties and rubbers.

Cons: None

I would recommend this kit to anyone who has a simple system. All around good kit.

Worked very well for the money, great value for my system! Only thing that kept me from giving this 5 stars across the board is the design of the fuse holder and how you have to change/connect the fuse, minimal complaint.
