Question about Car Audio & Video
I have 2 8 inch w7s they are 3 ohms i am trying to hook them up to a 2 channel 1200 watt amp the amp says that it is 2 ohm stereo stable but when i hooked it up the amp cuts of when it is turned up.
if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

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.

A 4 ohm DVC sub can be wired in series like you described for an 8 ohm load or the voice coils can be wired in parallel for a 2 ohm load.
If your 2-channel amp isn't stable down to 2 ohms when the channels are bridged (most 2-channel amps are only stable to 4 ohms when bridged), you do not want the voice coils paralleled. The amp will overheat, go into protection mode, and eventually fail completely. A sub with 2 ohm voice coils would be a better fit. That way, you could series the coils for a 4 ohm load and the amp would operate OK with the channels bridged into that load.
But anyway, for the best power from THAT amp to THAT sub, your best wiring solution would be to wire each voice coil to a separate channel. The problem with that is that the signal to each coil needs to be EXACTLY the same or you will have one coil trying to move the cone out while the other one tries to move it in. You can closely approximate identical signals on the output side by using the same input to both channels. Do this by using only one RCA connection (either right or left channel) from your head unit and split it with a "Y" cable.
Hope this helps.

if the amp has a 2 outputs then i would wire the two 4ohms together, and the 2ohm by itself. and if its a 4 channel output then wire them all sepretly, if its a 1 channel output then wire the two 4ohms together and leave the 2ohm sub out
