Bridging a 4ohm sub on a 2 channel amp.

[faceman516 10+ year member]

I was told that if I bridge a subwoofer that is 4ohms on a 2 channel amp that it would make the amp only see 2ohms, is this true and if so why? I understand the dual 4ohm and making it 2 ohms but the 4ohm on a 2 channel making it 2 i can't get.

Whoever told you that is lying.

youre using both channels for power so each of them sees half the load. best way i can explain.

I stand corrected.

so basically what i was told is correct. Because I had a dual 4ohm sub bridged on a 2 channel amp that was not 2ohm stable and it kept blowing its fuse and I was wondering if that was the reason.
