Bridging, Still dont get it...

[Kastlez_ 10+ year member]

This is the first time i've ever dealt with a class a/b amplifier so bare with me.

Everything is already hooked up but i had a few questions about fine tuning to make sure its all good.

AMP: mm 100.4

Bridges @ 4ohms

It's bridged like this:

I have the rca's from the H/U plugged into line output CHANNEL 1 & CHANNEL 2 only??? does it matter that channels 3 and 4 are left out

* Switch is turned to MODE: 2 CHANNEL (vs 4 channel)

* Gains are matched channel 1&2 with channels 3&4 (correct?)

Yeah that's all.. input is appreciated

you got it wired right.

i never ran it bridged, but i think its supposed to be ch 1/4 for RCAs(at least was when i wired up a MBQ amp)

I've tried a few different combinations they almost seem to sound the same.

Any second opinions about the RCA outputs?

it might be internally bridged..

to tell check the balance.. balance to one side and the other.. if its right its good. if its not move rcas around accordingly..

channels 3 and 4 need a signal if you plan on using them unless you put your amp to 2 channel input

Thats what im thinking because it seems like they arent getting enoug power even though bridging is supposed to increase rms to (2) channels at 4ohms.

I tested checking the balance but both sides are audible even switching back and forth from my h/u

Im going back to only using two of the four channels.. briding just isnt working for me
