Wow...!

This amp is really cool... not only does it look good but it sounds good... it really made my speakers come alive... i have a pioneer avh-p7600dvd headunit and on a recent trip to california i watched independence day... WOW... it sounded so good... beyond my expectations... just make sure you set your crossovers well... this amp made my 6x9's sound like small subs and super super clear... no distortion at all... all in all... great bang for buck... HIGHLY RECOMMENDED
