Re: AMP FOR MY SONY SUBBS
Get an amplifier that is rated just under the power ratings of the subs, that way you will not blow the subs by pumping in too much power to them. An example is, if you have 2 subs that are 500 watts each and you are going to connect them in stereo mode, you need an amp that is no more than about 400 to 450 watts per channel. This will push them very hard, but will not blow them by overdriving them. If you are going to connect 2 subs at 500 watts each in a bridged mode (in parallel across both channels) then you need an amplifier that is about 800 to 900 watts total power for both channels. This is basically the same power ratings for an amp, but some amps are mono (just one channel) and will have just a total power rating, while other amps are 2 or 4 channel amplifiers and have a rating for each channel.
I hope this helps in your decision making, if you need more help let me know. I have been repairing car audio equipment for almost 20 years and have seen just about everything.

MY BEST GUESS FROM WHAT YOU HAVE SAID IS THAT THE BOX WAS TO SMALL. BUT YOU ARE OVERPOWERING THE SUB RUNNING IT AT 2 OHMS ON A 750 WATT AMP WITH A SUB THAT IS ONLY RATED FOR 600. NO MATTER HOW FAR YOU TURN YOUR SETTINGS DOWN, YOUR STILL PUSHING TO MUCH POWER FOR THE SUB TO HANDLE. IT IS ONLY RATED 600 WATTS FOR A REASON. ESPECIALLY IF YOU LISTEN TO MUSIC THAT HAS A REAL LOW END AND THEN A HARD HIT. REMEMBER A HARD HIT WILL SPIKE YOUR AMPS OUTPUT THEREFORE PUSHING MORE WATTAGE TO THE SUB.
do you have caps before your power going into the amps, might not be getting enough power, check your settings on the amp, gain output make sure it in stereo and not mono and check your crossover, or splitter
ive been hearing alot of this going on yes you had youre system proffesionaly installed but youre amp is pushing at all its got it must be pushing at 1ohms capacity loud but what you dont realize is that.. do ur home work first some amps say they can handle the power but if you read carefully it would read not stable look up amp on the net before buyin review them first ...but evrything youve got is correct its youre amp it wont burn out but you wont get continous power to ur spkrs ..i recomend installing one amp on each spkr same brand if you prefer in keeping it with a crossover if you dont have one that way they wont over heat and cutt off and you will use less power and get more bass...
0.6 cu ft per driver is awfully small for those subs. The polyfill may help, but I doubt it's going to make the subs feel like they're in a box 2x the size. It's sounding more and more like you may have the wrong subs for the situation. You may want to see about getting some different speakers (10's maybe?) that are tuned for a smaller box and 4 ohms each.
That's not a 1000w amp. It's a 400 watt amp when loaded to it's lowest rated load. If you have one speaker per channel (the only safe load if you have single 4 ohm coil speakers), you're only getting 165 watts/speaker. It's probably distorted because you're driving it to clipping.
it might not be the amp that is not working it could be the sub or sub's. Try takeing a sub out of the box and look down the hole in the center of the magnet on the back of the sub and look and see if you can see any wire's or any thing that has come unwound in the sub and if you do see wire's then you have blown your sub. If you dont see any wires then you could completly disconect your amp for 20 to 25 minutes and then plug it back in and see if that fix's your problem. If none of this works then you can take your amp to an audio store and have them test the circut board in your amp.
