2 channel amp bridged to 2 speakers

Me and my friend got in a fight the other day, he said you could bridge a 2 channel amp to 2 speakers, he swears you can, and im like: "You ass, no you cant". I don't know what hes talkin about, do any of you, heres a pic(sorry, i drew it in like 2 secs):

the way you decribed it in the picture....it looks like the speakers are wired in series, which is possible for the amp to handle...IF the total impedence is high enough that it isn't below what the amp is stable down to.

I think GSteg has it right, it could be done, whether you'd really want to could be a different story.

ok, bridging a 2 channel amp and 2 subs is simple. most subs anymore have 4 connections on the back right? 2+ 2- so you run a short set of wires from one sub to another. then off the second set of terminals, either sub, run those to the amp, bridging these wires, and there you have it. pretty much its not a complete circle, your just pushing 2 subs off of one bridged channel.

if you wire your speakers in series, you will want them to be of lower impedance than what the amp is stable too, because the resistances of the subs add in series. if you do it in parallel, make sure they are greater than what the amp is stable down to, since the resistance lowers when they are in parallel.

in series: Req = R1 + R2 + R3 + ...
in parallel 1/Req = 1/R1 + 1/R2 + 1/R3 + ...

if there are two speakers with the same impedance, the equivalent resistance is double the original in series, and half the original in parallel.

That's only if a speaker has dual voice coils tho...

very simple, say u have 2 single coil subs, u bridge the amp, take the possitve wire and run it to one sub, and also to the next, and do the same with the negative, if u have 2 4 ohm subs, this will run them in 2 ohm mono to ur amp, make sure ur amp can handle it or it wil cut out


1 DVC sub in parralel = 2 ohm
2 DVC subs wired in parrallel = 1 ohm
3 SVC subs wired in parrallel = 1.3 ohms
3 DVC subs " " = 2.67 ohms
4 DVC subs " " " = 2 ohms
4 SVC subs " " = 1 ohm
