Title: boss Ava 1404
Review: This product is three tings in one. It is an amplifier, equalizer, and cross over for the sub woofer. The last two were not completely working, a quality control problem. But, they do a work with increasing base and general radio really nice. For 20 to 30 dollars the price is still right.
