It's a good amp for the price but spend a little and you can get a lot better. I recommend this amp though even for the price it's at. It's strong and sounds good but the Alpine PDX sounds better. I've had problems with Alpine though, but MTX hasn't let me down yet with their gear. I'll tinker with it some more and see if I can get the SQ to improve a bit but over all it's solid.
