at first i was a littel esceptical about the quality of this product when i first ordered but when i got it hook it to a power amp i was so amaized about the clean quality of sound as well as the responce of all the controls and even better when i tested the subwooffer out put it was so good that i decided to order 3 more for my sons inlaw because for this price you just can't beat

Warning! Dont think this is a 4 band parametric eq as stated on the box. It is really only a 4 band eq with sub out. The difference is you can't select which 4 bands of frequency to boost or cut as on real parametric eq. If your looking for 4band passive eq with a sub out this will work fine. But most all radio's have these features allready built in.

good sound and good quality recomend good for the value

Very easy to install, and worked right out of the box. Needed a solution for my 5th wheel toy hauler sound system to connect by tv, DVD. Worked great, and the price, couldn't beat it...

Item did not function, with the exception of the panel lights.

I love this product the install was easy the sound quality is nice the sub controls are very nice.if you are reading this BUY IT!!!!!!
