Ok, my friend just bought a JL W0 12. I think he has a single 4 ohm sub. I didnt know they had that for jl, but.... anyway he needs a good amp, he plans to add another jl W0 soon so a good amp recommendation for 2 jlW0 12's would be greatly appreciated. I'll get back to yall on the voice coil situation later.
is that gonna be the rite amount for the sub/subs, they're only 125 rms a piece. thanks for giving some input, ill check ebay and stuff to try and find those amps for a reasonable price. I found an MTX 401, it pushes 420 rms at 2 ohms for 239.99 on the dot. That should be a good amp for the set up rite. Please elaberate on this if anyone has any input. Thanks.
actually the 12W0 is rated at 125 watts RMS. look at the JBL bp300.1 it'll give you 150wRMS to one sub and the same to each when he adds the second one.
Killa. Thanks Glass. So when you have a mono ch. amp and it pushes 150 rms, it will push 150 to each sub if you put 2 subs on that one channel? Thats cool, I thought it would divide the watts in half. So on my Punch P3001 thats about 400 rms on one channel will push that 400 rms to each if I hook up two? Killa. Thanks alot.
o sh!t, i just realized that the ohms would drop from 4 to 2 so double the watts and that would be 300 rms between two subs, is that why it would be 150 rms to both? I read some people sayin that if you had an amp that pushed 500rms @ 2 ohms and you gave it a 2 ohm load with two subs, it would push 500 rms to each sub instead of 250 rms to each. Is that right?
Nope. If you were to put two 4 ohm subs on a mono amp, equalling a 2 ohm load when wired in parallel, and the amp put out 500W RMS at 2 ohms, then each speaker would get 250W.
right concept though. two subs in parallel halve the impedance so while the power is divided between the subs, it's also doubled by having a 2 ohm load instead of 4 ohms. this holds true for all but a very few amps that have a regulated output like the JL slash series amps, which put out the same total power regardless of load between 1.5 and 4 ohms
