My sub amplifier can provide power at 2 ohm stereo. I have 2 12" 900w
max 4ohm subs. Currently I have them running at 4ohms. I decided to
try them at 2 ohms from the amp (which is 420w RMS x2) I was very
happy with the result. Not sure if they were any louder but the lower
end seem to hang on to the end. At 4 ohms the lowend seems kinda
week, fizzles out early. I noticed at 2 ohms the headlights dimmed
ever so slightly. Maybe a cap might band-aid that.

Is there a problem with running my 4 ohm svc subs at 2 ohms?


If there was a problem, it would be with the amp, not with the subs. You have
them wired at 2 ohm mono, and your amp is rated to 2 ohm stereo. I'm not sure
what overall affects that can have on the amp... I've done it before and the
amp would overheat and shut down.
