This is probably common knowledge to most but I've gone through the last 25 pages of this forum and can't find the information I need anywhere!
I'm currently powering one subwoofer with a monoblock amplifier, which is rated at 1640 watts x 1 @ 1 ohms. If I add an additional subwoofer, am I simply halving the power and running 820 watts to each? Do the wiring schematics have any effect? (ie: wired in parallel)
Thanks in advance to anyone who can help me out.

Yes, but it really all depends on your wiring setup (so yes to your other question too).  If you had your amp down to a 1 ohm load with one sub and wired the second in parallel with that it would cut it down to a .5 ohm load, now this would double the power your amp produces which would in turn really leave the same power running to your sub, but most amps arent stable at this so you would probably fry it.  Now if you were to add another 1 ohm load in series with it then you would raise it to a 2 ohm load which would cut the power in half basically giving your sub 1/4 of the power its seeing now.

It looks like that isn't an option. My amplifier is rated at 1200 x 1 @ 2 ohms as well. What would be the end result if I ran two subwoofers at a 2 ohm load? Would the subwoofers get adequate power in that configuration?
I would like to avoid adding another amplifier, if at all possible. For clarification, the sub is a Diamond Audio TDX15D4, which is rated @ 1200 watts RMS.

Alright, you could add another sub, wiring each sub in parallel to reach 2 ohms, then parallel wiring them together to the amp for a 1 ohm load which would run 820W to each sub.

yeah pyrofish has the right idea there, not exactly optimal power for those subs but if you are sticking with just that amp then that is the best way to do it.  Parallel them all together and get 820 to each sub.

Sorry, you can NOT post a reply.
