big 3 upgrade kit

This is an perfect kit to do the big 3 upgrade. It actually contained enough wire for me to have sufficient wire up everything up front and to complete the ground and distribution block wiring for my second battery in the trunk. Would highly recommend.

Great KIT!Best BANG for your BUCK!

At first I was a little skeptical about the kit but once I got it turned out to be great. I installed it on a 02 cavalier and it fit perfectly, and for $50 for 0 gauge what else do you want.

Im currently running 3 amps in my car and this was definitely a great upgrade. Would defiantly recommend to anyone that's on a budget and wanting to do a BIG 3 upgrade.

Instant Sound Quality Improvement

I installed this in a 1998 Grand Prix GTP, the entire install took about half an hour. This was well worth $50!! Before this, I was having problems with headlight dimming when the bass would hit, the entire car would sometimes shut off, and the windows were getting slow. After I installed this, the engine seems to crank over (start) faster, no more of the entire car shutting off, windows seem to work faster, and best of all-- a significant improvement in sound quality. I also had a lot of alternator whine prior to this installation; this kit seemed to greatly reduce that (it's still there, just not nearly as noticeable). One should take note, that this product DOES NOT come with the extra ring terminals as shown in the picture.

Skar audio....THE NEXT BIGGEST THING

I got 2 pair of the spx-65c and they are we built and package.. I would diffintly buy more Skar equipment

Great and Easy to use.

Was curious if I was going to have to put the ring terminals on myself and I'm glad they came already on. Came with everything needed to do this upgrade and had easy enough instructions to follow even if you didn't know anything about cars. Would recommend it to anyone whose looking to do this upgrade.

pretty nice

it gave me less flex in my voltage, but made my motor and trans run and shift noticeably better. now if I just upgrade my alternator, every thing would be good.

Great Purchase

Instead of adding a second battery I bought this, 100% worth the purchase. I never have any electrical problems or power drops. The wire is true 0 gauge. XS power makes great products, I highly recommend this upgrade to anyone.

Upgrade

Used this to upgrade my electrical system when i put air ride on my 63 cadillac, worked great. Comes with everything needed, would recommend.

Works great

Used this along with a 1700 watt brz-1700 and a 30 farad capacitor. Just what I needed. A little hard to get through the firewall but that's because I didn't want to drill any extra holes, so a little dry lube did the trick
