you usually have to make one the master and the other a slave. the slave amp would have to run 180 out of Phase. on my amps i have to bridge the negs together, (amp to amp) then pos on the master goes to pos on woofer and pos on the slave goes to neg on woofer.

There is no master/slave function on the 275. The manual is for other models as well and the master/slave is listed under features for the ms-250 and mps-2220. Doesn't matter anyway, all the master slave function does is set the gain on both at the same time. I'm sure you can set them both the same.

It also says very clearly under Electrical Installation:
Note: For bridged mono operation, connect the speaker to the Left + and Right - terminals.

Read item # 2 under Controls and Functions.

^ IIRC and as mentioned, I believe all the Maste/Slave feature did was tie the gains together and I think supposedly sync the power supplies for better sound (yeahoksurewhatever).

Nice amps What are you powering the top end with?

yea i just would lik to do it up right............im running a alpine iva-D310,running the boston accoustic pro speakers in my car(factory 5.1) speaker system.running those with my M50 pg and then running my 2 PG ms-275 amps . One each to each sub (12") r types in a true alpine made box. sounds nice and loud but i dunno i just can't figure out one thing.On my head unit for some reason after 15 on the volume **** it's all bass up and not highs. but other then that shes rocks.(driving a chrysler 300 /05)

oh almost forgot also have a POWER ACOUSTIK 5 FARAD DIGITAL CAP

another thing that sucks is the trunk is super sealed not alot of air flow for that base

That would mean that with the gain setting on the M50 you top it out at 15 on the volume. Past there it is already full blast but the 275s still have more to go.

You probably need more power on the top end.
