When my factory radio died, I needed installation parts to put a CD stereo into my older Mercury vehicle. Sonic Electronix had everything I needed, which they helped me find with very friendly service! The prices were great, too!

I use this to power 2 JL Audio 7.7's and a 10" sub on my golf cart. Works great. It is mounted in the engine compartment, open to the elements and I've had no problems.
