Conclusion: This amp is great. I have had it for six months without a flaw. It is very compact and sounds awesome no matter what I am listening to. Sonic Electronix had the best deal by far so I would recommend them for all of your electronic needs.
Summary: I'm very impressed with the quality of sound with the Rockford Fosgate amp. And the power it delivers. Thanks so much to Crutchfield for the quality of products they put out, and the Awesome tech support they have also..

Conclusion: I replaced a terminater 1200w amp with this one because the terminater was overheating frequently. I am totally satisfied. Sound is crisp and clear. The thump my 2x 12" subs make is incredible.
This supplies more power that expected and looks great too.

Summary: I have had about a dozen sound systems ranging in price and quality. This is my second RF system and it does everything I need it to do. When I had my son I had to downgrade my sound system so I could have the trunk space I needed. I have the P400-1 running one 8" sub in my rear deck and two bass shakers under the front seats and it sounds and feels like I have 2-12"s in the trunk.
