[QUOTE="ericfg, post: 5288221, member: 604739"] Hello. My first post here. My previous sub amp quit working (along the lines of the 'inline fuse' thread below) and has been replaced. The system: old amp - PPI A600 2 channel bridged subs - 2 12" Mmats SVC Wavedrive(?) wired in series new amp - RF Punch 4080DSM 4 channel bridged I'm following the RF manual in wiring/bridging. The Rear output Left+ goes to the speaker Left- The Rear output Right- goes to the speaker Right+ The Front output Left+ goes to the speaker Left+ The front output Right- goes to the speaker Right- Is this series or parallel? What kind of impedence are we looking at? The reason I ask is this amp is *much* smaller than the old amp but is much louder now as wired above. I have the gain almost all the way down. I'm thinking I'm putting the amp at risk with a low load. I have only two channel input to this amp at the moment and that is why the manual recommends this wiring (with the 180 switch enabled). I can easily make it four channel and then wire the speakers in simple stereo. Would this result in different (4 ohm) impedence (and therefore be preferable)? I hope this explaination is clear.
