Amps on woofers are fine just won't hit

I installed my 2 12" dvc 2ohm woofers and i have a 1400 watt amp to get to 2 ohm i wired my woofers in series/parralell. the amp is bridged but no sound will come out of the woofers (sometimes i turn my woofers off from headunit then on and they sound for like 10 seconds then turn off again) i installed it two days ago worked great for about 10 minutes then stopped and i would appreciate any input anyone has to offer

Your probably making your amp run to low ohms if its a 2 channel amp bridged to one channel you can probably only run it at four ohms

Also seeing as your subs are 2ohm dvc you can't wire them individually to 2ohm and use each channel separately. So i'd recommend buying a 2ohm stable monoblock or running it at four ohms. a 1400 watt amp'll still pound at 4ohms and it'll extend your amp's life span

Wiring 3dvc woofers to infinity refrence611a which way would it sound at its best and perform at it peek

Your question can't be answered without knowing the impedance of the subs. Are they 1 ohm, 2 ohm, 3 ohm, or 4 ohm coils on those dvc subs? Are you saying your amp IS 2 ohm stable?

Infinity 1250 watt dual voice coil wiring diagram

how you wire it depends on your amp, I assume that the sub is a 4ohm DVC from what you have provided.
Parallel:
If you have an amp that can handle a 2ohm stable load you can connect one voice coil + and - to the amp and then run wires across the sub to the other side + to + and - to -

Series:
If your amp won't support 2 ohm you have to run it at 8ohm, to do this you connect from the amp to one + and to the - on the other voice coil on the sub, you then run a single wire between the + and - terminals .

Below are some images to help

Need to wire two dvc 15 in kicer l7 to 1 ohm

Hello goldy6569,

To wire the L72's at 1ohm, simply connect both +'s and -"s on each sub together. Then connect to your amp terminals.

With 2ohm DVC's, you can have either a 1ohm load or a 4ohm load. The diagrams are here (I know it's the website of a Kicker competitor, but their "wiring wizard" is simply the best).

Hope this helps.

L7 wiring options

yes it should work fine i would bridge them up to 4 ohms each speaker then bridge them back bye conectin them on the amp by puting the red with the red and puting the black with the black if the amp only has 1 chanel then put both speakers red on the same positive on the amp and same with the negative now to bring the ohms up to 4 ohms conect the solid red to the black with dot with a short wire ok then the ones that are not run together will go to the amp giving offf 4 ohms and with the 2 speakers bridged together thay will reduce to 2 ohms witch means that eatch speaker will get about 600 wats of rms from the amp

huge shared common space slot loaded box (size depends on sub 10", 12" 15" you need to clarify that please) the amp specs on earthquakes site say the phd5000 is rated at a max output of 5k watts at 1 ohm 3k watts at 2 ohm so, with 3 dvc 2 ohm subs you only have 3 options of which only 2 will be a usable solution:

1. 3- 2ohm dvc series at sub parralel at amp = about 1.33 ohms at the amplifier this is the best option to get the most power to the subs as each sub will produce a 4 ohm load then wire each one to the amp the amp sees 3 4 ohm parralel loads which = 1.33 ohm so based on the amp specs you would be close to 1200 watts per sub.

2. 3- 2ohm dvc wired in series at sub and all 3 subs series wired together very difficult to wireand will give you a 12 ohm load which is next to no power at all (not a viable solution)

3. 2- 2ohm dvc parralel wired to each other and then at amp the amp sees a 1 ohm load and makes 5k watts max but you can only (REREAD THAT LINE! ONLY USE 2 SUBS IN THIS WAY) WHICH GIVES THE MOST POWER BUT ONLY USES 2 SUBS
