A couple of years ago I purchased a Polk/Momo C300.2 amplifier and (2) 1230 Infiniti Reference Subs. They are single VC and wired in parallel, I think. Now I've heard that this isn't a good setup based on wiring but these subs kick. They are both bridged down to two ohm's. Is this ok or what? haven't had any problems yet. Also they are installed into a bandpass box that I feel isn't constructed properly. What should i do to ensure greatest SOUND QUALITY. Use both channels on my amp, change the sub box, use only one sub, or what? Don't want to hurt anything. Thank you for taking the time to reply! I appreciate it!
