great product

The following review is for BAK42BL, which is a part of the bundle you are viewing.

Works great nice tight packaging and you get everything you need for your amp. Also it is true 4 gauge wire unlike some kits that advertise the wrong gauge wire this one is correct the correct size they say. Will buy again

Belva BAK42BL

The following review is for BAK42BL, which is a part of the bundle you are viewing.

Disregard the rating for durability because I have only had this product installed for a week. This kit is quality for the money. The wiring is a little sparse for 4 gauge, but it's definitely not 8 gauge in a 4 gauge sleeve. Loses one star for ease of use because the ring terminals must be crimped on by the user (which may be difficult if crimpers or a vice are not accessible to the user). Overall, I would recommend this to anyone on a budget or looking for a wiring kit for their first system.

Good kit on a budget

The following review is for BAK42BL, which is a part of the bundle you are viewing.

I bought this kit for a buddy of mine to do a small install in his 1999 Lumina. It's very flexible and more than enough for his little daily pounder setup.

Beat kit for the $$

The following review is for BAK42BL, which is a part of the bundle you are viewing.

I ran this to my 1200 watt sony amp with 2 1000 watt pioneer subs in a sealed box . And let me just say everyone in my neighborhood can hear me before they see me. I'm only at about 75% gain . I may but 1 or 2 more as back up for the future . People said the fuse holder dosent fit , I didn't use it , but all you have to do is back the set screw all the way out and slide out the inner holer and it will fit perfectly.

The following review is for BAK42BL, which is a part of the bundle you are viewing.

Bad thing is i had to buy extra gauging, metal pieces besides that everything is fine but if you want good cables buy(OFC) 1/0 gauge wiring itll save you time and money

Well Built

The following review is for BAK42BL, which is a part of the bundle you are viewing.

Very flexible and not thin. This wire is the right size nothing skimped. RCA cables meet expectations, a nice fit. Dark blue as opposed to bright red. Hides well.
