How can i make my jl audio 12w3-d6 into a 4 ohms


it depends if the amp is mono or stereo and if it is bridged. if it is bridged the amp cant handle the speaker the best way is to lower the level on the amp or connect it to only one channel. also you might want to check your ground cable use a thick one and make sure its making good contact with the chassis. this happened to me. luck

Do you know if my woofer is blown?


well if you hear a rattle sound its probably already blown...and the amp could be drawing too much power if the radio shuts off...make sure all your wiring is correct. also if your car is off and you turn it up it will most likely shut off cause the battery cant handle it. but as for the sub i think its blown. good luck

Will a jl amp e1200 kick a jl woofer 12w3v2 loud


yes a 1200 watt amp will do the trick.. the problem would be in the box the 12w3v2 sub needs a good size box and you should have one made for your car. and yes you will get the bass you want

Dimension please for enclosure 12w3v2-d2


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.

12W3V2-D4 ENCLOSURE???


They need 1.4-1.7 cubic ft per sub(ported box) less if it is sealed but I wouldn't recommend that, it sounds like ****. Google "Re audio box calculator" and use it to adjust your dementions to your application

Car Sub JL 12w3 low sound


So I am assuming that you have just setup/wired this up recently? Have you had this working before?
You can have a look at the gain control on the amp & see if this have been set really low. This will help if the signal coming from your stereo is weak. The other thing I would suggest is to make sure that the amp can actually push this sub. I know what the specs say:

  • 1 channel audio amplifier
  • 1 x 350W RMS @ 1.0% THD
  • ThermalThrote full-on power assurance
  • 2 ohms stable (non-bridged mode only)
  • RCA type inputs
  • 0.3-6.0 VRMS input capability
  • Continuously variable High-Pass & Low Pass 50-250 Hz
  • Continuously variable Bass Boost settings (0 tp +12dB)
  • Frequency responce: 10-30,000 Hz
  • S/N >104 dBA at full power @ 0.1% THD
  • >80 dBA at 1W/1M
  • Remote gain control, mounting hardware & screws included
but I don't believe most of these. Many manufacturers embellish what their products can actually do! With the bigger more established brands such as JL Audio you will have no problems, their products have been tried & tested so much on the competition circuit.
