i really love this amp. i used it to power my 4 alpine type R 12s. the box was built by myself 8 cubes at 34hz hair tricks on normal music in my 2dr tahoe. the amp looks awesome you can make the whole set up look clean without having to add an amp rack. sonic was amazing to deal with i never have a problem when ordering from them. the amp is certified so you know you get the rms rating your shooting for. i will use two of these to power my new set up of 4 boston spgs i made it loud but want louder.
