Must have for Alpine Amp!
Crutchfield Customer Review (What's this?)
Great product to adjust bass on Alpine PDR-V75 amp. Some music requires more bass than others so this little guy is nice to have at your finger tips. I installed it in the ash tray of my F-150 which is a very convenient place for me.
Pros: Works great! Nice small size - could put it just about anywhere.
Cons: This product should already be included with expensive Alpine amps. Should have a white dot on the knob to know where adjustment is currently set at.
