ok i have searched the forums and i couldn't find the answer to my question.

i have 2 jl audio 12"w6 dual 6ohms 300 watt RMS each. i am looking for an amp that can run these two subs. if i run them in series it will result in 3 ohms. and if in parallel it would be 1.5ohms (correct me if im wrong)i been looking for some different types of amps and they are the jbl bp600.1 rated at 600w @ 2ohms. how many ohms should i setup my subs ? 1.5 or 3ohms? and one more question, will any amp that is rated at 2 ohms xxxwatts work with that setup also? thanks

your resistance is wrong....if you run them in parallel form the 2 subs in parralel will still have a 6 ohm load.....if you run the 2 subs in series you will have a 3 ohm load......If you are using DVC (dual voice coil) subs you can wire each sub to 6 ohms or 3 ohms.......thus giving you a 6 ohm a 3 ohm or a 1.5 ohm load

(2) 6ohm subs in series are a 3 ohm load

(2) 3 ohm subs in series are a 1.5 ohm load

(2) 6 ohm subs in parallel are a 6 ohm load

(2) 3 ohm subs in parallel are a 3 ohm load

well ok i got this from the jlaudio website....btw mines are dvc's. i have the coils wired in parallel.

still haven't my question, if an amp is rated 600watts at 2 ohms. and if my speakers were 300watt each @ 6 ohms. what would be the best way to wire up my speakers to the amp. series/parallel? thanks a bunch

Jonjon1 you are correct with the ohm load config. I have my 2 12w6 hooked up in a parallel config. giving me a 1.5 load on a ps series kenwood. Not the best amp but I was surprised with the remarkable pounding sound that it gave me. I have heard good things with that JBL amp that you are talking about. I have not heard that particular one, but it should work out just fine. I had a couple of Orions that were stolen but they were great! They went as low as a .25 ohm load stable. So answering the other question if you had more subs with one amp depending on all you had ofcourse then I would hook it up in series. If only two subs then I would use parallel.

You know you have the right amount of pressure when your eyes start to water! Now you've got Juice!

cool thanks Sound Pressure for you advice. also if an amp was rated at 2ohm stable can i still hook up my speakers to it if my ohms were 1.5?

No problem glad to help.

You will put some stress on the amp but not much!

I wouldn't go below the manufactures recomended resistance. When you check it with a multimeter you'll notice that the subs will actually pull less than 3 or the 1.5 ohms. If you wire them in series pulling a 1.5 ohm load look for an amp that can handle atleast 1 ohm. Or if you go in parallel try a power bd500
