Howdie, looking for advice on using a "free-to-me" Polk RM 1000W 19840 Sub in my current setup....I currently have a Rockford Fosgate Punch P325.2 amplifier running one Punch P2 12inch subwoofer. I am def a rookie when it comes to all the specific details, frequencies, ohms, channels, etc etc. I just hate throwing away perfectly good devices but if the free-bie will not sync with my current system then so be it. Just looking for yalls input.....many thanks in advance!!!
