I have a DB Drive PT1200.1D amp. Easily does 600 clean RMS at 2 ohms. Has a built in fan under the DB Drive logo. The logo illuminates blue. It's decently heavy and never gets even warm. It retailed at $599. I paid $300 for it. I'm looking to do a new bigger build so I'd let her go today for $175 shipped and insured. I have great feedback as well more than welcome to check it out. Here's a picture of what she looks like. Let me know what you think.
