If you increase the voltage, you increase the power output. If you lower the impedence, you increase the power output. The 250w x 1 rating is a 4 ohm rating at 12 volts. The 1200 w x 1 may be a 1 ohm rating at 14.4 volts.

The 12v ratings on all pg amps are totally inaccurate, and should be disregarded, dont even look at them.
Unless your trying to determine what class to compete in IASCA

If you're giving the amp proper voltage and not producing a clipped signal (gains, etc.) you should have no problems. Now the life of the sub will depend on the length of time you are playing it. If it's a long time, then the woofer will likely fail.

And no, the T1200.1 puts out a healthy 1200RMS + @ 4ohms. When i had mine, the birthsheet rated it at 1594@4ohms. These little amps are highly underrated.

if my setup is at low how long be for i kill the sub ?

This is a amp like the JL / series? If it is, you are going to kill the sub with this much power.

thank you

but haw long would it last ?

Depends on how the subs voicecoils can dissipate heat. Totally unknown.

you are asking a question like.....how long will my dog live.....or how many licks does it take to get to the center of a tootsie roll.....its hard to figure that out cause sound is first of all dynamic, second your headunit is a factor. third voltage is a factor. and so on and so on.
having the car on of off is a factor as well and there are way too many factors to predict how long it will last.

any woofer will last a life time if you take care of it.....or if can last 1 min playing full boar and it might last a split second playing a clipped signal...it might last 10 sec......too many factors to predict. you either need to give a tonne of specifics and then ask this one again or just take care of your equipment by not over powering. and taking it easy on those poor woofers/.
