Please explain this JL sub to me!!!

[JRuner1]

i was thinking about getting 2 JL w6 subs. but then i started hearing that because of the ohm level or something that it would be balanced to get 3. what does that mean? and would it not sound right if i got just 2? cause 3 subs is just too heavy for my little stock civic engine. if it doesn't sound right then what sub is comparable to it.... autobahn, phoenix gold, crystal mobie? thanks for the help!!

I'm not sure why it is that way, I know that the JL Audio 10W-6 has a Dual 6 ohm voice coil, and I have 3 of them wired in series at a 3 ohm load.

If your going JL Audio, depending on whether your a bass head or not. You'll get enuff base with just one, only point in having 3 is more bass. Definatly not worth it, if your not going for SPL.

many people are suggesting getting 3 JL W6 because since when you wire all three in parallel, you will get a 1ohm load. if you get two, it will present the amp a 1.5 load. usually company will rate the amp at 1ohm, 2ohm, 4ohm, 8ohm, etc. so if you're planning to get 2 subs, make sure you know how much power the amp puts out at 1.5ohm. also, be sure the amp are stable to 1.5ohm or lower. if it's stable only to 2ohm, DON'T TRY IT! most likely the amp will overheat and fry. maybe if you put some kind of fan on it then it'll have a better chance of surviving. to calculate the ohm the amp will see, simply use this equation:

Ohm per sub = total Ohm
number of subs

say you have 2 subs. each one is a single voice coil and 4ohm. so take the "4" (ohm) and divide it by "2" (total amount of subs) and that will give you 2 as your answer. you're amp will see a 2ohm load with 2 SVC 4ohm subs

PS. i got bored so i just typed all these down :finger:

OR even easier, buy JL Amps to go along with just the two subs, and you won't have to worry about the ohm loads as long as they're within 1.5-8 ohms. I've got two of them, they're killer.

fuck the w6 man. get the w7's. yeah!



or some audiobahn alums.

Two DUAL 6 ohm voice coil subs =

TWO 3 ohm loads
TWO 12 ohm loads (but why?)
SINGLE 1.5 ohm load

Three DUAL 6 ohm voice coil subs =

THREE 3 ohm loads (but why?)
ONE 4 ohm load (This is why 3 is recommended)
ONE 1 ohm load (This is why 3 is recommended)


By using three, you allow for 4 ohm or 1 ohm loads -- which are STANDARD amp type loads... TWO running STEREO would also be good, heres an example

Amp puts out...

200 x 2 @ 4 ohms RMS
400 x 2 @ 2 ohms RMS

Running TWO of the subs @ 3 ohms EACH you would get :

300 x 2 @ 3 ohms RMS

Take the differance between them, and divide it... and thats your 3 ohm power. Simple!
