For this class of amplifier, you can't beat this little dude. If you are expecting monster power look elsewhere, but if you want something that plays load enough to hurt your ears with clean, distortion free sound, this might just be the amp for you. I have this installed in a 2004 F150 attached to 4 Pioneer TSD6802R 6x8 and 1 Pioneer TS-SWX251 sub. I can't believe what a difference it makes! It trumps any factory system. This amp fits perfect behind the back seat and it was very easy to install.
