which would be more efficient? 500x1 at 2ohm or 500x1 at 4ohm?

which would be a more efficient amp?

a 2 channel amp bridged at 500x1 at 4ohm
or
a monoblock amp at 500x1 at 2ohm

[Wonderbread]

as in draw less current?
by using ohms law, the amp (assuming they are equally efficient) will be doing less work at 4 ohms, so thereby drawing less power..
however, the will NOT have similar efficiency ratings...
which amps in aprticular?

[mwess]

you will run cooler at 4 ohms. musical quality decreases with the impedance

[musicman]

I'm talking about the

soundstream 502 (2 channel amp that bridges into 500 mono at 4 ohm)
soundstream 501 (monoblock amp at 500 at 2 ohm)

[MUGEN!]

il go for the 500x1 at 2 ohms. though it heats up easily it gives better SQ~ its up to you man! the heat will be dessipated if you place it in a cool or spacious place like away from any other audio components - like towards the side of the trunk - not on the SUB BOX! just my 2 cents! your choice man.

wait a minute, according to soundstream it's bridged at 4ohm at 500 rms.

what do u mean by 2 ohm mono stable?

please explain in simple terms without using all these big technical words.

thanks

i tihnk waht he's saying is, it will run 2 ohm mono, but if the manufacturer doesnt say it will, in its ratings ie - give a ratinga t 2 ohm, dont do it...
in your case, teh D calss amp (monoblock) would probably be your best choice, as by nature they are more efficient
