I have run 2 12" jl w3v2 d2's for about 6 yrs now. I found that a box that is 1.4cu ft per sub is ideal. Google "Re audio box calculator" and apply the dementions that work best with you space. Also rememember to allow for the thickness of the baffle by adjusting your frequency a little lower than what you actually want it tuned to.

Hey,, i just bought the subs myself and was looking for the same thing as you are,, i looked at the jl audio homepage top see if i could find some awnsers but i couldnt even find the speakers there much less any type of dimension chart,, so i e-mailed their tech support and if it turns up anything ill forward what ive found,, and 1 cubic foot is not enough not for these youll end up overheating the voice coil for sure.. but id highly reccomend doing a series bridge at 300 watts X4 ohms for the best bass range w these speakers!!

Typically you use one cubic foot per sub, so a 2 cubic foot box will work fine. To build a basic one, just a rectangular box, using 3/4" MDF (excellent material for a box), cut pieces this way:

2 - 25.5" x 13.5"
2 - 25.5" x 12"
2 - 12" x 12"

This will give you an interior volume of exactly 2 cubic feet. Cut your sub holes out of one of the 25.5" x 13.5" pieces.

Bridging two12" subs and one 15" sub to my Rockford fosgate T 1500bd amp


assuming all 3 subs are 3-4 ohms, running all 3 in parallel (the 3 positive leads all attach to the amp positive terminal, and all 3 speaker negative leads connect to the amp negative terminal) will bring you at or above 1 ohm, which the amp is capable of handling. With 1500 watts, you will want to use 8 gague power leads for the amp, 12 gague speaker cables, and an inline 120 amp fuse between the amp and the battery, within 1 foot of the battery.

So how do wire this set set up to a bridged amp any help would be appreciated


assuming that is a dvc dual 4 ohm speaker, and you have a 2 ohm bridged amp, you run a positive from each side of the speaker into the bridged positive of the power amp, and run a negative from each side of the speaker into the negative bridged terminal of the amp. if, indeed, you have 2 4 ohm voice coils, running them bridged in parallel wiring will bring the load to 2 ohms. if you have 4 voice coils, of 4 ohms apiece, you could run all 4 parallel into the amp, but that would bring the load down to 1 ohm, and you would have to make sure you8r amp can support 1 ohm operation.

Lightning audio b150.2 as soon as +12 is hooked up blows 25 amp fuse and the c2 1000uf/35v capacitors blow???????


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.

RCA CABLES


RCA cables are the best way to get the audio from your head unit to the amp. If your head unit doesn't have RCA outputs, you might be able to use the speaker outputs of the head unit to connect to the "high power" or "high level" inputs of the amp, if the amp has such inputs (check your manual).
