You might need to just solder them better

I just got my PPI dcx 300.2 amp back and i hooked it all up, and connected the fuse back in and started the truck, the amp turns on but the red light starts blinking and says clip out. The amp doesnt smell...


Are you sure everything is correctly connected. If you are running the amplifier in bridge mode then take note that the load to the amplifier can be no lower than 4OHM. dreamsystems

My kicker amp goes in and out of protection, like when i turn the car on it turns on green then just goes red then goes to green again and goes back to red. I was bumping for awhile and just started hear...


Thankyou for the detailed fault description..it really helps!

sounds like there is one of these 3 things wrong:

1. leaky or partially blown mosfets on ouput power stage of amplifier are leaking DC onto speaker output causing amp to go into protect..this explains any banging or clicking herd.

2. There has been damage to the internal SMPS and is going into protect because of an internal rail over-voltage/under-voltage.

or 3. you have a shorted speaker lead or sub that is bringing the amplifiers load down to less than 2 ohms..buy or obtain a multimeter and have a poke around and check all your speaker leads on the ohm setting anything lower than 1.6 ohms and you have a short...also make sure that you have correctly loaded amplifier to..alot of begginer audio enthusiats overlook this important step and cook amplifiers!!

remeber impendance ratings, have a look on google, search "impendance formulas" and study up if your unsure!

hope this helps,ben

My amp keeps going off on protection mode as soon as the bass starts bumping


check powers and earth, unplug sub and crank it up see if it still goes into protect if it doesnt the sub is too much load for that amp and could have damaged the amp, if it still does it then its a fault in the amp or power problem make sure you have good thickness 4gauge and good earth

JBL amp, worked fine untill 2 days ago. protection light on..


might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.

The protection light keeps coming on


That means something isn't wired right. Make sure that all of the power inputs from the battery are correct. Most importantly make sure no bare wires are touching (IE the positive and negative bare wires going to the subwoofer terminal.) If it keeps persisting, check the voltage level in the car and make sure it is normal, because some fancy amps have protection where it will go into protect mode if the amplifier is not getting enough power to supply. Also, does this happen when you are really bumping (like high volume) or just the second its on it cuts? Because when you really play it loud and it cuts, sometimes you are putting too much a load on the amp. Make sure the fuse in the amplifier is the correct fuse for the amplifier.

Ppi dcx 1500.1 is it 2 powerful 4 da 12in. L7?


Hello montyski20,

The amp outputs 500 watts RMS into 4ohms, 750 watts RMS into 2ohms and 1000 RMS into 1ohm.

The L7 can handle 750 watts RMS (375 watts per each coil). If your L7 is the 2ohm version, you should wire the voice coils in series, the positive marked coil to the negative unmarked coil. Then connect the remaining positive and negative to the amp terminals. This gives you a 4ohm load (500 watts). If your L7 is the 4ohm version, wire the voice coils in parallel, both marked and unmarked positives together, likewise both negatives and then to the amp terminals. This gives a 2ohm load (750 watts).

Paralleling the 2ohm sub will result in a 1ohm load (1000 watts) and that is too much for the L7.

Hope this helps.

Mine has done the same thing. except its says "clip out"


sounds like it may be a power supply problem in the amp. If it was slowly getting worse, you may suspect a capacitor in the power supply to have failed, or popped. Open the amp, and look for any swollen tops of large capacitors around the big donut shaped coils. If any of their tops are swollen or bulged out, that's your problem.

Protection mode


Disconnect all speaker wires from the speaker terminals of the amp. If it powers up and doesn't go into protect when you increase the settings, the wiring needs to be checked. If it still shuts down, the amp may need to be repaired.

Does it shut down or make loud noises when you move the RCA cables where they plug into the amplifier?
