briding a JL Audio e4300 question

sorry, should read "bridging" ;)

this may be a stupid question but

is it possible to bridge channels 3&4 of an e4300 down to 2-ohm? specifically, for a dual voice coil subwoofer? what would you get?

i'm wanting to use 2-channels of an e4300 for a 10w3v2 and run the sub at 2ohm in parallel. does this make sense or is it even possible. channels 1 and 2 are going to a pair of coaxials inside the boat.

when you bridge the 2 channels togethor you can not go lower than 4 ohms. But at 4 ohms bridged the output is 150-220 watts which should be plenty of power a single 10. Go with a 10W3v2-D2 which will give you 4 ohms when wired in series.

william, i pm'd ya

check your mail

wouldn't a 2-ohm dual voice coil speaker run at 1-ohm in series?

if you go to jlaudio.com they have diagrams on wiring the subs in parallel and series and all the different combinations and it shows what the final ohm value.
and series on Dual 2 ohm sub is 4.
series doubles the ohm and parallel divides it in half

okay i see that since my last post, but back to the e4300...

doesn't bridging it still only give me 150 watts max, no matter what i do? you were saying 225, but i'm just not seeing that anywhere. i've looked at both pdfs.

i made a bunch of calls and everybody i talked to either told me it wasn't possible with the e4300 or that it wasn't worth it because it would only be 150 watts. i want to believe, it's in my best interest, i'm just trying to understand it better. right now, if i'm running 150 to the 10w1, i'm not sure how it could possibly sound better with a 10w3 which is less efficient and claims optimum power is 300 watts.

not on the website at 12.5 volts it runs 150 watts and at 14.2 volts it runs 220. boat batteries run at 13.8 volts if you have a enough power for all the electrical stuff in your boat and since this is a small amp it is most likely running at 13.8 volts

okay, huh, i'll have to talk to them again and see what they say. i wish i had room for the 450/4, the thing is just too dang big.

i have 2 10w6v2's on a Orion 1200d at 1 ohm which puts out 1200 watts. i have also run those subs on my 500/1 at 1 ohm as well which probably puts out 600 watts. And it was very hard to tell the difference in loudness.
The jl 10 w3v2 is optimum at 250-350 on the chart and is reccomended to have at least 75 watts and no more than 500.

personally i think with the w3 bridged it would sound great and be much better than the w1. the key to the sub sounding good is the box in my opinion
