I bought the Soundstream ST1.1000D to power a basic 12" kicker subwoofer. It sounded very nice but it would always go on protection once i would try to raise the volume. I tried multiple subwoofers, ensure that all wires are correct, and still no luck. Buy it only if you are not planning playing loud music or space is an issue.
Pros-
small as an adult shoe
looks good
plain and simple
cons-
does not push the advertise RMS
must use 10 ga or 12 ga wiring for your power and ground
