ST-AP6 1/2 Din Car Audio Digital Processor, 13.5V, Bass Maximizer & Sound Restoration w/Includes a Dash Mount Remote Control and Light Display, 10.4x2.3 x 8.6 inches

First one I got was bad so I returned it and was immediately sent a replacement. It works great! I have a bunch of old music and this thing makes them sound great. If your looking for an inexpensive filter/line driver this is for you.

5 STARS

This epicenter does the job , clear music and that deep sound of bass!! For the price its a great deal , adds bass to songs that don't have any only con is that it doesn't have herts adjustment but besides that i will get this anyday great product!

Si no eres muy exsigente con el sonido está Perfecto pero si le exsigente mucho este no es el mejor producto pero si ace muy bien el trabajo para el que fue diceñado

Only had this thing for a month and it shorted out on me and my sound system stoped working

I love it it has great sound my bass sound great now it comes with everything you need to install it and costumer service is great totally recomended

This bass proccessor works really great, am using it with a kicker amp and a kicker L7. I get really deep bass after tuning up my system. I have try expensive bass processor before and I see no major difference between both.

I bought this audio processor to get rid of the distortion feeding to my subwoofer and it seems to be working for that, there seems to be a little more clarity to the bass now but that may be in my head. Loudness seems to have remained unchanged.I would be satisfied with the product except it requires you to actually open up the unit and change jumpers on the board in order to change the output power. Very annoying and was only briefly touched on in the directions.
