Amp shuts off when music turned up

I have a sony xm-2002gtr 2-channel amp and i hooked up two 1300w sony 12" subs. I connected both + and - together and connected them to one + and one - on the amp. Every time i get a song with a lot of bass the amp turns off and i have to turn my deck off before it works again. Is there something i can do to fix this or should i just connect each sub to one channel each?

Try adding a capacitor to feed the amp. these are large in capacity (farads)and dims (about 6' x3' dia.)...what wire size are you using?

Can I hook up 2 single coil subs at a 2 ohm load on my sony xm-1252gtr?

If your sub woofers are SVC (single voice coil) 2 OHM each, then connecting one to each channel would make the amplifier run in 2OHM stereo Then again, if your sub woofers are 2OHM each, it would be better to connect both together in series and connect them to the BRIDGE specified speaker terminals of your amplifier making it run a 4OHM load into one channel. This will give you all the power the amp can give and still run stable. A 2OHM load into one channel will likely damage your amplifier. Do not forget to set the LPF (low pass filter)on if you are going to use the amplifier to run sub woofer/s. dreamsystems

Xm-2002gtr amp keeps kicking protect light on

check your amp and speakers and make sure their both hooked up 4 ohm instead of 2 ohm because if you have 1 set of voice coils on your speakers they can only be hooked up four ohm and not bridged to your amp because if you keep trying this you will lock up your speakers if the speakers are only 4 ohm than just hook them up regular to each channel on your amp if your trying to brigde four ohm speakers to your amp it will keep going into protect or worst case scenario you will fry your speakers and you can check your ohm with a ohmmeter trust me my brother owns a stereo shop

Only one sub works

The amp should produce no output when using the left negative and the right positive.

If the amp works bridged (left positive and right negative) with one speaker AND works when you connect one speaker from the left positive to the right positive, it would appear as though the right channel isn't getting any signal.

Try inserting only the left signal cable (nothing plugged into the right RCA jack) to see if the right channel will work when a speaker is connected to the right channel speaker terminals.

Can it power the subs? Yes.

Can it make them crank? Well, that all depends on your expectations. That amp/sub combo is going to give each sub about 125W, which isn't much. But if it's what you have, it's better than nothing. You might also consider using only one sub and bridging the amp. This would put about 340W on the one sub, which is much more reasonable.

Protection light keeps coming on

Check the wiring between the sub and the amplifier. That's seems to be the only thing left that could cause a problem. If it's shorted to ground or pinched so the conductors are shorted together, it could cause the symptoms you listed.

You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.
