I have bought a 12 channel power amp an ArtSound AMP1250 to make a pair of Gale 401 speakers active.
The Gales have a pair of LF drivers, a mid and a tweeter each. I plan to use all 12 of the 50 Watt amps to power the various drivers through an active crossover of course.
It would be good to power each LF driver with a pair of 50 watt amps and indeed there is a facility in the amp to bridge a pair but the bridged amp requires a minimum load of 8 Ohms. The drivers have a minimum impedance of half of that. I could connect the drivers in series and use the bridging option but it occurred to me that I could connect two power amps in parallel and use them to drive each LF driver. More current delivery and low impedance tolerance would be the advantages.
Is this a possibility? If so, is there anything to look out for to make sure each amp's output does not interfere with its partner? I am only investigating this in order to use all the amplification at my disposal, each power amp has its own gain pot and that is how I will balance the overall sound once set up.
I will put some sort of soft start up or speaker protection into the system to avoid a fat mains switch on thump trashing the tweeters but the possibility of pairing up LF power amps is attractive if it works!
All offers of advice will be gladly received.
