Sounds Great with my 6x9 5 channel Pioneers just make sure that the fuse on the back is seated properly the stereos amplifier stopped working the day after I installed it and I thought that it had broken I was going to send it back for another when i removed it and examined the unit i pushed on the fuse it made a click noise and has worked perfect since . The customer support was great they had no problem sending me a new unit without having me to send back The wiring harness that i wired each speaker to but didn't end up needing a new unit
