Alpine PDX1600 / PDX-1.600 / PDX-1.600 Mono Channel Digital Amplifier
I added this amp as part of my complete nose to tail Alpine System in my 2001 WS6 Trans Am.  Alpine IDA-X305S Head unit, Alpine SPR-17S in the front doors, Alpine SPG-17C2 in the back seat area, Alpine SWR1043D Sub and originally Alpine PDX-5 - Amplifier - 4-channel plus Mono-power.       The SPR-17s sound amazing, very nice clean highs and good mid bass. The SPG-17C2 are great for rear fill and sound quality as well. I was a bit disappointed on my bass.. most songs the 1043 Did not show up.. Installer said
