Alpine PDX-4.150 Car Audio Amplifier

at the ebay price this top of the line alpine amp is awesome. very clear and crisp. I have mine pushing 2 alpine type s 5x7/6x8 component sets aswell as a type s 6.5 component set and they get down even with my gains like 3/4 the way up. if you get it in your local store you will pay an arm and a leg but in a good ebay store it is a steal. granted if something does go wrong you cann't just bring it back to the store you got it from but I think it is worth it to save like $200-$300.

I've bought this amplifier to drive the other Alpine equipment I've bought. I was expecting "good enough", but it was more than that - it was just excellent - Money well spent.

The sound was clear and loud, and if used with other Alpine equipment, you will get your money's worth.

If you need CLEAN CLEAN POWER this amp is it. The pdx amps also have great efficiency at all volume levels, this will have a very low load on the battery and alternator compare to other amps. These amplifiers also have a very low interference and can be installed any where in the car or truck with out the worry of increased interference.
