Trying to figure out if I can bridge the two channels on this amplifier, and run it mono? The amplifier says it runs (4 Ohm Stereo Power (RMS): 125W X 2). Is this setup even possible on my one 15" SUBWOOFER? or do I need two drivers to be able to run stereo? Or is my Only alternative to run (4 Ohm Mono Power (RMS): 400W X 1) ??
Whichever setup given, how much can I turn the gain up to? ex. 1/4, 2/4, 3/4 ??
For 4 ohm stereo you would just run it off one channel (with only one sub you would get just the bass from that channel), at 2 ohm stereo you would need two 4 ohm subs wired in parellel.
"at 2 ohm stereo you would need two 4 ohm subs wired in parellel. "
So your saying, each sub, for a total of two subs, is wired so that each subwoofer is wired into the +/- of its own channel, each sub having their own channel?
Or are you saying.. wire it so it's bridged but you use either the + of one channel for both sub + terminals, or the - of the other 2nd channel for - terminals on both the subs for a bridged connection?
No I'm sorry, My last answer wasn't clear. For 2 ohm stereo on a two channel amp you would need either 2 subs capable of being wired for 2 ohms (DVC 4ohms per coil, or a 2 ohm SVC) or 4 subs with 4ohm SVC (same as yours).
Your options are either run it bridged mono (follow manual), you'll need to turn your gain down so that you don't damage your sub, or run it off a single channel so it would get 125 watts.
I'd run it bridged personally just make sure that you set the gain so that you don't blow your sub. Start with gain set at minimum and your volume set at about 3/4 then increase gain to get the sound you want or get distortion.
