Alright here is my situation
I have 2 12 JL w3v2 in a sealed box.
with a Kenwood KAC 9103D Mono
I wired them in series to 4 ohms.

My sealed box is now broken so i bought a New Ported box.
My dillemma is that the ported box doesn't have hole in the middle so i can't connect the subwires together.

I dont know what i should do!?
i definatly don't want to drill a hole in the middle because there is 3 layers of wood in the port.

 

Which 12W3v2, D2, D4 or D6 and what did you wire in series, the subs or the VCs?

For a 4 ohm final load I would assume they are D4, with VCs wired in parallel, [2 ohms] and then the speakers wired in series, [back to 4 ohms].94

 

Okay i have gotten some help and suggestions.. but im not sure which one to do.

I called cartoys and the guy said instead of connecting wires to the sub together from the inside of the box, connect the wires from one terminal of the sub, to the other, from the outside. that makes sense, but is this method used alot?

The other is from crutchfield
"Most mono amps have two sets of speaker terminals for convenience of installation: if you are hooking up two subs to the amp and using large-gauge wire, it gives you a place to attach the wires without having to trim them, appearing as if each subwoofer gets its own terminal. But in reality, these terminals are actually tied together inside the amp — both positives are going to the same place inside the amp, as are both negatives. If you are using more than two subs, then you simply use parallel or series wiring (or a combination) to get as close to the minimum impedance of the amp as possible"

After reading this article i noticed that i do have 2 speaker terminal in my Mono Amp.
Did i read this correctly does this mean that I can just wire my Subs like this V V V and it would be my regular series, 4ohm load wiring?

Help please Sub/Car audio experts.

 

To FCM: my JL w3v2 are D4
and My voice coils are wired in series.
just like this http://akamaipix.crutchfield.com/ca/...4-ohm_mono.jpg

btw fcm thnx for responding so quick.. your always a great help in the HT community.

 

You have it correct, wire each speakers voice coils in series, now you have (2) 8 ohm drivers, which will give you a 4 ohm load when paralleled at the amp. Wire them independently to the amplifier, you are good to go. BTW, what is the amplifiers output ratting at 4 ohms vs. 2 ohms?

Car Toys hu........

.....just kidding, I'm employed there.

4ohms output is 500watts rms.
2ohms output is 900watts rms

i know my subs can handle the 900 watts but, i dont think my battery can for long.. lol

 

As mentioned your wiring is correct and as also mentioned wire each boxes two terminals to the amps two sets of outputs.

The JL Audio 12W3v2 "continuous power handling" is 300W, for a total of 600W continuous,your amp is a little underpowered, although as long as you do not over-drive the amp into constant clipping it should work just fine.94

 

both the solution will work. doing the wires outside in stead of inside. and the amp being mono with the two outlet. both the same results.
