Everyting I anticipated very pleased its heavy and well made one hell of a boost. Thank you Sonic

At first I was a bit concerned that I would be investing in a low grade piece of equipment ..... I was wrong. Unbelievable sound quality and very simple to operate and install. Visually appealing ,clean appearance, and switchable red or blue illumination. I purchased this product to run with my Samsung Galaxy 10.1 tablet so I could have more control over audio adjustments. I was surprised to notice that this device eliminated engine whine while my tablet was docked and charging. Very nice.

This EQ, crossover is a must have. Cleans the sound up, and reinforces the music.. Controls are esay to adjust. The 9 volt out makes any H/U sound amazing, and all this right from your dsah!

I really love this unit. It does what it is suppose to do. It will make a big difference in ur sound . Night and day difference. Buy this unit u won't be disappointed.

This preamp gives you full acess to your finger tips so you don't always have to go in your trunk to adjust you amp gain settings. it has amzing crossover peak points, so for the money for thgis product you cant go wrong.

This does what they say it will do. I love it and you will to.
Buy this and let it do what it do.
