Sound Stream Amplifier

I purchased this amp because of its size and location where I was mounting it. The amp fits perfectly and I hooked it up to my factory head unit. The sound and volume are excellent for my needs, I'm going to buy another one for my Harley.

Install this amp on a 2008 harley ultra classic. Cuts out at half volume. Makes a popping sound in the 6 1/2 polks that where installed at the same time.
