I think it depends on the speaker itself, it should say on the back the sreaker, most likely on the magnet, what ohm the speaker is.

Sony Xplod

If your still getting a green light, it at least sounds like the amplifier portion may still be funcitonal. Perhaps your inputs are blown. If your comfortable with electronics, pop the cover, and try patching a signal directly to the amplifier stage. and of course check your source.

2 Subs running together

If they have the same impedence (like 4 ohm) then you should be able to run two different model number speakers as if they were the same model number. There might be a slight difference in the way they sound, but I would not expect it to be enough to be noticeable. Good luck.

you probably have blown speakers or the wires are disconnected

It should be better to use the Pioneer GM-7200M Amp with your subs.

For 8 ohm setup hook up this way:
Amp out+ to Sub1 +
Sub1 - to Sub 2 +
Amp out - to Sub2 -

For 2 ohm setup hook up this way:
Amp + to Sub1 +
Sub1 + to Sub2 +
Amp - to Sub1 -
Sub1 - to Sub2 -

How to

First of all, make sure your amp is bridgeable. There are a few ways to bridge subs. series: hook one wire from the negative on the left amp output (or whichever is labeled on amp for bridged)to left sub negative. left sub positive to right sub negative, then right sub positive to the amp positive output.(like a big loop through both speakers) parallel: both speakers get their own set of wires, both negatives go to the bridge negative terminal, and both positives go to the positive bridge terminal. Series-parallel: A combination of the two. say two speakers in series, and one hooked up alone, but all to the same amp outputs. Bridging your amp/speakers basically lowers the resistance of the circuit and makes more current flow, more power, louder, harder hit. In series, it also makes both speakers do exactly the same thing, instead of "stereo sound" or L/R differences. What you're probably looking to do is Bridge in parallel. That will drop the resistance of the circuit the lowest, allow the amp to put out the most amount of current to the speakers, and allow your bass to hit the hardest. If your amp only has one output, hook up the same way as above. Just see what resistance your amp is stable down to. If down to 1 ohm, no worries. if stable only to 2 or 4 ohms, you may want to bridge in series to be safe. That will cause the resistance to go up, and will not pull as much current through the amp. The whole time, just remember Bridgeing and higher current mean HEAT so watch your amp. I hope this helped.
