i have a solution for you and everyone here....wherever u took it to test the amp let them check how they are wired up..in series or parallel....it seems the way the subs are wired up to the amp are dropping the resistance level and the amp can not handle such a low impedence level and its why its causing it to cut off...its a safety feature for the amp so you dont burn it out...try wiring the subs a different way and you will be fine...than again it seems you dont know what the hell your doing so take it to a professional place and let them do it for you.

Exactly. If you don't understand what "impedence" is, or how to spell it for that matter, then you probably shouldn't have hooked it up yourself.

Click that, print out your instruction manual, and stop pretending like you don't need it. Go to page two and look at Example 3. That's how you're going to wire your subs up. That will run your amp at 2-ohmns and thus, get all 600watts out of its one channel. That should be PLENTY for your subs to handle constantly.

If for some reason your system still continues to take a dump, it's probably your amp being redic. Check your ground. Otherwise, just bring it somewhere.

your amplifier has an indicator LED on the top which should tell you if it goes into protect mode, to start you should see if that is happening, if you don't know what I'm talking about look in the owneres manual for the LED.

I have 2 alpine type Es currenlty running off 2 different amps, but I had them running off a 500 watt mono block amp for a while fine.

There is alot of possible problems, first off your subs are rated to draw up to 750 watts, so if putting your volume up past 16 is pushing the amp to draw lets say 600 watts per sub, now ur pulling out 1200 watts from a amp which is rated for 650 RMS, now the peak power of the amp is unknown to me, but if its less than 1200 it may be overpowering it, and since your running in 2Ohms it is really easy to do this.

Second problem you can have is that yes your subs are 250watt rms and you have a 650 watt rms amplifier, therefore you should be able to run both for about 500 watt RMS and be completely in the clear. But the thing you have to realize is that the specs that are givin by manufacturers are under perfect conditions, this means that the amplifier was probably running in an air conditioned room about 65-70 degrees, not your car in the summertime (which mines was 160 degrees inside today) that effects your performance because its much easier to overheat an amplifier in 160 degrees then in 70.

Second thing that could be effect is your voltage, i dont know how much you know about electronics (not much from what ive seen so far) but Watts is Amps x Volts, if your battery is running low then for ur amplifier to keep up it is going to have to pull more amps to compensate, well the more amps it pulls teh more easily it can overheat and go into protect mode. Again the test was done in optimum conditions which is 14.4 volts (what your alternator outputs) but thats assuming you have a 50 watt alternator hooked up directly to your amplifier and not running anything else in the motor, so if your voltage is low becuz u have a computer and speaker amps running off a stock battery and stock alternator now your sub is drawing too many amps and again is going to go into protect. Also if the voltage drops to a certain point the amplifier circuitry doesnt have enough power to run and will shut off completely if the protect light isnt even going on.

so my advice is, check your voltage while your are using the subs as you slowly increase the volume and see how much it is dropping, try putting a fan next to ur amp with the trunk open adn see if it does it still, and check the LED indicator, after youve gathered all the results come back and tell us what you found so we can better help you fix your problem.

ps: i agree with everyone else, learn to type :-p
