Less power when bridging amp!?! Wth

[rtiid22 10+ year member]

It's a jl audio 300/4v2

I'm using a volt meter and I get a reading of 17.6 volts on channel but when I bridge then, I get a reading of about 1.2 volts, what's going on??

Are you measuring right at the amp? The L + R channels should be the same and the bridged connections should be double that.

^^^This. If the volts are fine on all 4 channel separately then you're measuring something wrong.

I don't mean to insult your intellectual but are you sure you are bridging it correctly, different amps have different terminals for bridging
