I have a nice Alpine PDX 4.150 amp for sale. Looking to get $250.00 for the amp. I will pay paypal fee and shipping. Was running mids and highs in my truck, but I have upgraded amps and do not have a need for this any longer. Never overpowered or abused. Condition is 9 out of 10. Has some minor scratches on the surface, nothing major. (see bottom photo)
