I agree with lyttleviet go with the arc audio ks 300.4. I think it's 90 watts x 4 at 4 ohms and 175 watts x 4 at 2 ohms. S/n ratio of 95 db's. It's the same amp I'm going to be running. I'm ordering mine tomorrow from audioliquidator.com for $258.70 plus shipping. They only stock. A stock products and they match the manufacturs warranty.
