This amp is perfect! I have it mounted behind the rear seat in my truck and it fits perfectly... I use this amp to power a pair of Alpine SPS-619 and a pair of SPS-609 all at 4 Ohms.

The sound output is over the top amazing and very clear. The connector's on the side of the amp being the "screw type" are no issue what so ever. Go out and buy some "fork" style crimp connectors and problem solved.

The fact that this amp is 2 Ohm stable means I can upgrade my speakers later and not have to upgrade the amp. I've had my system playing at full power for a 2.5 hour drive and not a single issue with the amps (both Pioneer; GM-D9500F and the GM-D8500M).

This is a very well designed amp and it has a very classy look to it. If I had to buy another 4-channel amp in the future with these specs I will buy another Pioneer.
