I could use some wiring help with my suybs and amp. My amp is a rockford forsgate t3002 and is capible of 1ohm stable in stero and 2 ohm stable in mono, it also has two channels. i have two dual voice coil subs that are 4ohm per coil. What is the best way to wire this seup? How do i know if i am in stero or mono? Thanks for all responses......

To run your amp safely, you have two options with your current subs.

The easiest way is...

On each sub
Connect the +'s together
Connect the -'s together
This will make each sub 2ohm
Connect one sub to each channel
You will be running 2ohm stereo

More complicated...

On each sub
Connect one of the + from one voice coil to the - on the other voice coil
At the remaining terminals (one + one -) your sub will be 8ohms
Connect the + from each sub to the + on your amps left channel
Connect the - from each sub to the - on your amps right channel
You will be running 4ohm mono

Since your amp makes the same power in either configuration, I would go with the first one.

could i wire this setup to 1ohm load and bridge the amp??? Would this be in stero or mono? here a wiring diagram..... http://www.rockfordfosgate.com/rftech/woofer_wizard.asp?submitted=true&woofer_qty=2&woof er_imp=4
wiring option number one.

I came up with an error on that link titled "woofer wiring hazard"?

Yes you can wire it that way. it will cause the amp to run very hot, and waste alot of power in the form of heat while not getting any more power out of it.

wat would my rms power pee channel be at 2 ohm if its 194 per channel at four ohms.....

I can't see anthing on your link, but if you hook a 1ohm load to a bridged amp, that amp will effectivly "see" a 1/2 ohm load. Your amp is NOT rated to handle that load and will probably go into protection if your lucky. If you are not so lucky...PUFF the magic smoke gets out.

if thats the case why couldnt i wire them to 4 ohm and have the amp see a 2 ohm load bridged and get the 2 ohm bridge power out put rather than useing each sub in its own channel at 2 ohms.....???? or would this be the same thing ?

You can, that is the second option I listed.

2 ohm stereo and 4 ohm mono will give the same amount of power. Also, on some amps when you bridge them, you are using only one side of your power rail. By going 2 ohm stereo, you could gain a little more control of your subs.

Your amp is rated to make 100x2 at 2 ohm stereo, so 200 watts
Your amp is rated to make 200x1 at 4 ohm mono, so 200 watts

If you are looking for the highest ratings on your amp you would need dual 2 ohm voice coil subs.

With dual 2 ohm voice coils you could present your amp with either...

1 ohm load on each channel, your amp is rated to make 150x2 at 1 ohm stereo
2 ohm mono load, your amp is rated to make 300x1 at 2 ohm mono

i now fully understand also i called rockford and they said to do it in 2 channels and the amp will actually be putting out 300rms per channel because it is underrated and during test at 14.4 volts it put out 300watts but is rated at 100 rms at 12 volts so they arent sued.......
