Well thanks for the advice. Of course what you didn't understand from my first msg, is that there is a front only switch on the amp. Sorry I should have been more clear. this switch enables me to run both front and rear channels off the front input only, therefore not having to match up anything. I have successfully hooked it up...it runs awesome! I also hooked up my phoenix gold line driver, which has a handy little light the turns on when I'm at risk of damaging the speakers (or sub in this case).
Of course I agree with you both when you say there are major risks when you have to try to match up gains and crossover's and such. I would also advise people not to even attempt it...unless you have a switch which will enable you to do so safely, do your reading and understanding before you test...and asking never hurts!
thanx again

So even though you have this neat little switch, test to be sure.

has anybody ever actually had a problem when doing this. I mean it's one thing to say "its not a good idea" but has anybody ever heard of actual problems with having the gains set improper?
again...read the pdf I linked two posts ago. It provides an interesting point of view.

i heard that you might infuriate mr electron man and he will cross electrifry your magnetic molicules which will make your speaker nolonger work
p.s. what im saying is there should be more internet no nothings to no nothings
i can now see where mtx gets it marketing ideas

wrong, soo wrong. wrong. the front switch enables you to run BOTH front and rear off the front channel input but you still have independant gains between the two. i would just run the rear to the sub and the front to your speakers. its an ok setup thats what i am running now its works pretty ok.

That switch that you speak of enables you to only use the front RCA inputs to run both front and rear channels on the amp. The thing that I would be worried about is the amp itself and how it is designed, are the front and rear two different power supplies? There can also be a power difference from one FET to another, so even though you're bridging the amp into a 2 channel, there will most likely be a power difference between the two, there will most likely even be a power difference un-bridged between all four channels.

All you're effectively doing is changing what channels are controlled by the gain pot. Regardless of the setting, it will still be a 4 channel. Two pots for the 4 channel input mode, and one pot for the 2 channel input mode, which leaves you to dink around gleefully with the second one because it has no function in 2 ch mode.

Actually on most amps, both gains remain active when the switch is set to 2 channel input. However there are some that the second gain becomes inactive. I would still check with a DMM to make sure that the output from both channels is the same, otherwise you are wasting alot of performance.
