[QUOTE="n2audio, post: 2222656, member: 540940"] Sounds like your power expectations are way off. That amp is 170x2 at 2, 250x2 at 2 (or 500w bridged). 500w is the most power you can safely get out of it, no matter what wiring method you use. Tri-mode is basically running the amp at 2 ohms stereo - 4 ohms per channel from the small speakers, and 4 ohms (each channel will see half the 8 ohms) per channel from the sub. The speakers get 1/2 the power, and the sub gets the other half. So 125 per spkr and 250 to the sub. That means you'll have to run the amp full range with a pair of high pass passive crossovers for the speakers, and a low pass passive for the sub. As it seems you've heard more than once...In the price range of the Kenwood amp you can get a decent 4 ch and make this a whole lot easier. something like [URL="http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=12788"]http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=12788[/URL] would do a great job IMO here's another good one -- [URL="http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=12979"]http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=12979[/URL] [/QUOTE]
