Having problems with a Crunch P1500.1 amplifier.

Question

Alright I have asked this once and not had many answers. I recently installed 2 12in hifonics square 1200watts max 600watts rms subs. I have a Crunch P1500.1. It is supposed to push 1500 watts rms at 1 ohm. I have them wired at 1 ohm. I have an 8 gauge power wire ran to the amp with a 60amp fuse. The amp is mounted on the back of my box. This way i can see the crunch light up when i put my back seats down. I also have an off brand amp running my 6x9s. I have a power wire running from the crunch amp to the other amp. I have this hooked up in a 97 pontiac grand am. The crunch amp is grounded under my back seat where the seat belt. Most of the levels of the amp are turned very low. If they are turned up the amp will go into protect mode. After about 10 minutes of running the subs the amp felt very hot to touch. The bass k**b running to the amp is supposed to stay green at all times and will turn red when the amp goes into protect mode. When the bass hits hard the bass k**b will half-flash red and go back green. The problems with the amp are that I cannot turn the levels of the amp up and it gets very hot after about 10 minutes of playing.

Answer 1

listen to jmann

but you also have another problem

" I have a Crunch P1500.1. It is supposed to push 1500 watts rms at 1 ohm.---  I also have an off brand amp running my 6x9s."

i hate to be the barer of bad news but that Crunch amp is "an off brand amp" and you would be lucky to get half of the advertised RMS wattage and it would more than likely be distorted (look into CEA-compliant brands)

"it gets very hot after about 10 minutes of playing." you need to upgrade the amp because its over working itself trying to push those subs and the lower the final impedance (ohms) at the amp, the lower the sound quality so at 1ohm its probrably distorted because of a incorrect gain (input sensitivity setting) settings

Answer 2

It sounds like the amp is going into protect for under current. You could really use a bigger power wire. I would assume that the grounds are 8 gauge as well. Replace it all. Go with at least 2 gauge. Don't Jumper the power wire from one amp to another either. The amps are not made to be wired this way. Every time the last amp in the chain calls for power, the other amps will suffer. The right way to fix the problem is to run the 2 gauge to a distribution block and then run a separate 4 gauge power to each amp. Also, use at least 4 gauge for the ground. If you don't have at least 12 gauge to the subs, fix that too.

After fixing the proximate cause, You need to fix the root cause of the current problem. That would be the alternator. look for a high output alternator. At least 150 amps. and upgrade the big 3.
