Summary: I was expecting too much from the Amp.. it really does sound nice.. although wanted a little bit more of a bass kick but.. I have it connected to my IDA-x305s and sps-600 speakers in my '06 evo ix se. overall midrange sounds great! full range sounds a bit better...i was hoping i didnt have to buy a sub...guess i'll now need a sub...which i was hoping to avoid but.. this is the reason why i got this one for the 5 channel feature.
Summary: This amp save you from having to install another amp for sub woofer, unless you really want a powerful bass. For me, it's good enough. The amp is small enough to install under the passenger seat. The unit I received was defective because one channel is not working. AudioSource was quick in responding to my email and resent a good one right away. This prove that shopping at Amazon give me confidence. Others take too long to response or never care.
Summary: I felt compelled to write a review after owning and playing with this amp for a month.I read alot of reviews before buying and they were mostly positive with a few sub power complaints.I've been a car audio fan for more years than I like to mention,and tend to stick with JL,Boston,old Kicker or MB Quart speakers and Alpine or old Blaupunkt amps.
