Planet Audio PX1500M Amplifier Problem

I recently installed a Planet Audio amplifier in my vehicle. It worked fine for 2 weeks and then it suddenly stopped working out of nowhere. Short details about my setup: - (Cable) 4 gauge power - (Cable) 4 gauge ground - (ANL Fuse) 200 Amps - (Regular Fuse) 30 (In Amp) - (Amplifier) Planet Audio PX1500M [1500 Watts @ 4 ohms] - (Subwoofer) Kenwood KFC-W3013PS [1200 Watts @ 4 ohms] - (Amplifier Features) "Power" & "Protect" light indicators To better help understand my situation, as I stated before, I was driving and listening to music and everything was playing fine as it always does and then suddenly out of nowhere the sub stops playing. As I head home, I check to see what caused the problem and I noticed that the "(Power)" light of my amplifier is not lit up as it always is. As soon as I see that, I immediately checked to see the (power) and (ground) connections to see if they are not burned or lose. Seeing that that neither of the two are the problem, i still cut off a new tip for both ends of both cables to make sure that it's definitely not burnt. After I did that, I powered the amp back on and its logo lit up as usual but the amp would still not push the sub or even display the "(Power)" light. I checked the fuse and even went and bought some new ones hoping that would fix it and nothing. Both the fuse on the amp and the one in the engine bay were fine. Checked the sub and tried it on my friends system and it still bumped so I know the sub is not blown. Also overheating is not a problem since I've turned the car on multiple times and the amp still does not want to play through the sub. So my questions are: Why is the amp not pushing power through? Is my amp blown out? Can it be fixed? The help will be greatly appreciated!

Need to check your ground wire it has worked news from where you got it hooked up at or at the amplifier even though it seems like is hooked up if is not properly plugged up or if it your amplifier will come on but is not getting the necessary ground to work properly you may also want to check your Hotwire make sure that it is plug up properly and at the battery terminal make sure that it is not corrodedalso are you sure you are getting enough wattage to your amplifieranother words is your battery putting out enough power to it

Sounds like your power supply to the amp. Make sure you location has plenty of air flow around it and use at least 10 gauge wire to the power input. Same size on the ground and make sure all contacts are clean. Your alternator will run hot when the sound is cranked and the car is moving. The heat lowers the amperage output of the alternator and will cause the amp to cut in and out.

It worked for a week and now im getting no power to my subs

if it stopped suddenly i would check the fuses and work your way back to the where the remote start wire is attached. if you where pushing it hard the fuse is likely. also check the connections on the amp closely.

Today i turned on stereo system driving in my car, and i have 2 12"inch t1 Rockford in a box with kicker zx300.1 it all hooked up on my car for like weeks ago and work great, but today it stop working...

Hello charlietmn,

First off you need to turn your vehicle on, turn the stereo on. Go back and look at the amp. Do you see a power light on ? Is it green or red ?
If there is no light or a red light on, your amp is not getting power or is not grounded correctly in which you can try the following:

Check and make sure your ground cable is grounded properly. It should be attached to your vehicles frame on bare metal.

You can also check your fuses, in your amp, and in the power cable for the amp.

In my experience installing car audio, those are the two most common simple issues.

Post back after you've checked the things I mentioned. I will assist you further if you need further help. Thank you for choosing Fixya and have a great day.
