Strengths:
Looks great and is flexible.

Weaknesses:
Easily scratched. Not as powerful as the older Autotek Mean Machines.

Summary:
I bought this one to match my XS1500.1. I replaced an Autotek Mean Machine 130 which was an older amp from the mid 90's. The sub amp is a good amp, but I have been disappointed with this one somewhat. Maybe because the 130 was a US built amp and not made overseas like the Stealth series, but it was stronger and cleaner than this new 900.4. I plan on selling the 900.4 and replacing it with Autotek's new Mean Machine 4 channel. Maybe it will meet my expectations. Still, it is probably better than most out there because the quality has dropped over the years with what I have tested. I just have owned some of the best over the last 14 years and expect the new ones to perform well also.

Strengths:
Great chrome finish. Lots of features. Can drive your whole system. Easy to install.

Weaknesses:
Be careful, scrathes easily

Summary:
To get an amp to sound horribly loud is easy. For it to be obnoxiously loud and still have superb sound quality, well ... now that's impressive. I'm using this amp to drive my whole system. Sounds perfect! Just won a second place with it at an SQ contest. Looks good and sounds better.
