Yes, you'll have to reset the gain(s) on your amp(s). Knowing the voltage won't really help you since you need to this by ear anyway. No I don't know what the voltages are on those 2 units.

he should set his gains by DMM, not by ear..

Or by O-Scope...

I've always done it by ear alone. I've never used a meter for that except for matching my 4 channels on my subs.

YES, I did. I use 4 channel amps on my subs.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Why? Well, I originally wanted to use a PRS 720 on each sub but they were all gone and Pioneer wasn't making them anymore. I had (2) PRS 340 4-channel amps so I bridged them to 2 channel and ran each side to each 4 ohm voice coil of my subs. So now I run my 720 to my 6.5" midbass and a 320 to my 4s and tweets.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Each 4 channel puts out 300 watts x 2.
