Amplifier problems!!! My Motorjoy 1000watt amp just quit one day. When I first purchased it I did not have it bridged, but one day I decided to and did. It seemed to work fine for a while until I noticed running, what I would call excessively hot. Then all of a sudden it popped, and quit. The light on top witch is usually green when working turned red and it would not run my sub woofer. The next day I tryed to turn it on and it worked fine for awhile then made the same popping noise and quit again (note: still bridged). It came back on a while later and to same process once or twice more and then would not come back on, the light continuously staying red when not working. I have replace all fuses I can see but the red light still stays on.

Re: Amplifier problems!!!

It sounds like your running your ohms to low, check to see what the amp can power and then read up online about ohms and your subs and how they should be wired

It was laying on the workbench in my kids stole the fusesWhat size fuses go in a koiiler model 9696 1000watt Max amp? To bridge this 4ch to 2 on the high input side. do you have to tie the input side??...

NO dont tie the inputs. Inputs stay just as they are. Outputs are where the bridging happens.
You amp specs are:
MAX OUTPUT POWER (2 OHM): 200W X 4 = 800W
60W X 4 @4 OHM (240W) LESS THAN 0.3% THD

So lets take 800 watts and divide by 13Volts DC = 61.54 Amps
So if there are 2 fuses start with 30 amp. To play it safe you could use 25 amps and if they blow try a 30. Now if the 30 blows you may need to take
another look at your wiring. I think 30 will be fine though.

Have SONY Xplod 1000watt dual ch. amplifier pushing two 12" MTX Terminators. About a week ago my my Sub on the right side quit working, while the left side sub is still banging hard as ever. I...

Check your subwoofer for resistance. It is more likely you blew a sub than a channel on the amplifier. If your subwoofer has no resistance, which can be checked using a multi-meter, then it is blown.

I have an american legacy series 2 1000watt apm

Check and see what size fuses it uses. Your watt power means nothing without good fuses. My suggestion would be to go buy 40a fuses and replace the ones you already have.

Can the sony xplod 1000watt amp be bridged for more power to just one sub? also what problem would cause a subwoofer to make a slight burp noise whenever the car is shut off or into the non accessory...

This amplifier can only be bridged for a single subwoofer with an output rating of 380 watts bridged. The amp is not rated for 1000 watts.
The burping noise you here is the electronic switch discharging power off on the large capacitor that are used in high performance amplifiers. Regards, rcampsr

Amp has 3 modes on it ,as a switch,what is this,it has a 2,3,4 channel mode,i have the gold dhd 1000watt x4 channel

first thing 1000@4 means 250w per ch. which means150w usable power.the mode switch is only to reduce rca cables,use 2ch mode if only 1 pair rca available,60hz is a bit low for this amp,90 would work better.
