quick ? abt sub wiring

T Titan · 02-14-2007, 12:36 AM

i have a set of 10" w3 jl audio single voice coil 2ohm subs and a set of 10" kicker cvx dual voice coil 2ohm's. i conected the cvx's but only using one of the voice coild. conected the 2 subs paralle so i'm getting total of 1 ohm load. the amp is 1 ohm stable i wanted to get as much of amp as possible so i'm looking for 1 ohm load. with this set up the cvx's hit better than the jl audio w3. is it safe to just use one of the voice coils. i read some info on this all i could find was that performace of sub would not be as good and that the air space needed for sub would have to be recalculated i'm assuming less air space needed. but in my case it sounds better than my other option. (jl audio subs are 300 rms) (cvx's are 600 rms)

More air space would be needed. You probably can't feed them full power either (I know DLS makes subs that you can). SO you should PROBABLY only be feeding the kickers 1/2 power... It depends on the sub if it is safe or not to even use them in this way. I don't know about kickers but I doubt it is a good idea with them.

When they hit better do you mean they are louder or more clear? just curious.

Are you sure you didn't hook the positive and negative up backwards on one of the JL's? This could cause some phase problems.

I would suggest that you hook up one kicker with both voice coils at full power and test, then test the other hookd up to one coil (like you have it now) atr 1/2 power and see what you are missing out on :P

You need to have both voice coils connected on those subs. If only one coil is connected you are only powering half of the coils windings. That is basically like hooking up one sub when you have two. I have never seen Kicker list enclosure specifications or TS Parameters for their DVC subs using only one voice coil. You have the wrong size enclosure if the subs sound better with only one coil connected. If you want a 1 ohm load you will need dual 4 ohm subs wired in parallel mono. A pair of dual 2 ohm subs can be wired at 2 ohms or 0.5 ohms mono. A pair of SVC 2 ohm subs mono will also give you a 1 ohm load. What amp are you running and what enclosure? W3's can handle as much power as the CVX's and IMO sound better in the process. Kicker lists Peak RMS for their subs while JL lists Optimum RMS for their subs. The CVX and W3 subs can handle about the same amount of power. Kickers power ratings is simply a marketing strategy. Both are nice subs but there is definately something wrong here.

kickers are 600 rms 1200 peak jl audio 300 rms 600 peak the amp i'm using is hiphonics 1200 watts at 1 0hm rms 900 watts at 2 0hm rms. i'm using tech 12 enclosure with abt .80 of air space. i check all the conection on the jl audio they are right. what i did is i played a couple songs from diffrent cd's to compare on jl audio i crank HU to abt 20 with the kickers i crank it to abt 15 to get the same amount of sound i get with jl audio at 20. the bass also seems to hit a little harder with kickers. i don't know maybe its in my head it's just that the kicker weight twice as much than the jl audio and i'm just assuming they have to sound better. .80 that's not too much airspace for the jl audio right i know minimum is abt .50 i think .

Have you tried the kickers in series at 2 ohms for 900 watts? The single coil JL's in series would give you 2 ohms as well (450 per driver), but it might be too much power for them, but in parallel they'd blow for sure.

Weight means nothing. 0.8 is on the small side of the CVX recommended enclosure that is why it seems like it will handle more power and 0.8 is on the large side of the W3's recommended enclosure so it won't handle as much power. I could see the Kickers getting a little louder with that enclosure but not sounding better. Both subs are actually 600 RMS MAX. You really need to leave each pair of subs in the enclosure for a couple weeks and break them in. Play with the gains, crossovers, etc and listen to a wide array of music.

Too much power is a good thing. JL's can handle more power than they claim for sure. Wiring a pair of SVC subs in series will give you a 2 ohm load. Distortion and under powering is usually what blows subs.
