can i wire 2 speakers in series then ad 1 more speaker in parallel to the 2 in series.   for instance... i wire a couple 3ohm speakers in series to make 6ohm. if u wire a 3ohm and a 6ohm speaker in parallel then that makes 2 ohms. is it possible to combine speakers with different impendence.

for some reason it seems as tho ill have 2 speakers at 6ohms and 1 at 3ohm. and that seams like an unstable load for at 2ohms

This must be too tough a question for you guys. I mean I know its probly talked about somewhere on this sit. But who wants to go look for it.

Your math is correct,
However your speakers will NOT each get the same power.
Example, if your amp gives you 100watts at 2 ohms it does not mean that each of the speakers will get 33 watts. This is because the load is not equal.
You also mentioned that the amp can't handle?
Are you bridging a 2channel amp?
Most 2 channel amps are only 4ohm minimum on bridge.

the amp is 4 channel. i will be bridging it and runnin 3 speakers on 1 channel and 3 speakers on the other channel. 440w each channel @2ohms. 110 watts per speaker at 75%.... 145 watts per speaker at full power. speakers are rated 120w rms.

you said each speaker wont get the same power.. example... would 2 of the speakers get the power the amp would give at a 6 ohm load?? and one speaker will receive the proper 3ohm load???

I was hoping that all three speakers no matter what order the series/parallel is that they would all equal 2ohm and therefore receive the same(equal) amount of power.

What kind of amp do you have that is capable of running 2 ohms bridged?

Just for the sake of easier math, let's use 400 watts per channel.  Said load will divide the power as follows.  The 3 ohm speaker that is by itself and not seriesed with any other speaker will recieve 2/3 of the available power.  The 2 speakers wired in series will recieve 1/3 of the power.  1/3 of the total power which will be shared by the 2.  So each of those speakers will recieve 66 watts.  and the single speaker will see 264 watts.

over looked the specs. the amp is stable at 4 ohms bridged not 2. my bad.

thanks for the info. u said just what i needed to hear. and i wont be wiring my speakers that way.

perhaps u could help me iamanidiot. I curently have (3) pairs of tts6.5 soundstream components, and (1) trx4.880 soundstream amp.

I have the means to buy one more set to make (4) pairs. [I have 4 mount holes on each door]

Lets see if i need to buy that 4th pair or not

what would happen if i put a 1.5ohm load into a 2ohm channel?? would it ruin my amp? say i only kept it at 75-85% gain?

rather a 3ohm load into a 4ohm channel bridged??

oh and by the way my rub2.6000 soundstream list it bein 4ohm stable bridged and i have two poweracoustic mofo's wired up at 2ohms... plays all day long cranked up.

I amm postin too much on my own thread!!!!!!!!! come on folks is loud music and car audio out dated or is it just not popular on this site?

I run my 4 ohm capable amps at 2 ohms.  But I have the means to fix them WHEN they break.  Notice I said when and not IF.

a 2ohm stable amp may survive a 1.5 ohm load do to box rise.  what ever speaker is wired to a higher ohm even if the total load seen on the amp is 1.5 will receive less power. power flows the path of least resistance, 2ohm+2ohm can equal 1 ohm add a 4 ohm 2+2+4 =0.8 but the 4 ohm sub will receive less power. this is a parallel equivalent

Thanks sport fury. I trust in my soundstream. They wouldn't make their speakers that way if it was bad for their amps. Don't u think?
