SONY Marine Gear Giveaway

Customer Testimonial

I shopped around for a car stereo, picked the one I liked, and found it a Sonic for $25 less than at the local store. And with free shipping, how could you possibly beat it?

This was a pretty good buy but it wasn't perfect. It didn't come with any crimps for my ground wire to connect to my amp. Luckily I had a lower level kit that I didn't want to use with my system laying around. I saw another review about the fuse holder. Same here. Wasn't something I had seen before and took me a little while to figure it out. I used this to connect my 2 Kenwoods in my 97 civic myself 6 months ago. All the cords were a good length except maybe the power cord. It fit but I didn't have really any slack. The wire was definitely true gauge wire. Haven't had any problems since I've hooked it up. Little pricey for the inconveniences but it does the job well.

I have always been a big fan of rockford and usually like to stick to just a few brands. Had this amp kit on my last civic hooked up to a rockford P1000-1D amp and this kit delivered the power! This is a true 4-gauge amp kit unlike some of the other kits on the market. Will never buy a different brand amp kit again!
