COLEMAN INVERTER PMP1200 JUST BEEPS WHEN TURNED ON


It is most likely the low voltage alarm. Suggest connecting when the car is running with no load (110 volts not connected). If the alarm continues turn the unit off and on to reset.

Hope this helps?

Inverter Protection Features
• Short Circuit Protection. The inverter will automatically shut down until short is removed.
• Low Voltage Alarm. An alarm will sound when the voltage from the battery discharges to 10.5 +/- 0.5 volts DC. This is an indication that the battery needs to be recharged.
• Over Voltage Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the input exceeds 16.5 +/- 1 volt DC.
• Under Voltage Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the input is less than 10.0 +/- 0.5 volts DC.
• Overload Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the continuous draw of the equipment being operated exceeds 1200 watts or the surge draw of the equipment exceeds 2400 watts.
• Thermal Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the circuit temperature exceeds 150° F

The portection light on my alpine mrv-1507 wont let me get any sound


remove the rca wires and the speaker output wires and just leave the 12volt power/ remote/ and ground connected. turn on the radio and see if the light goes off. if it does then one of your speaker or rca wires are shorted, plug in one at a time and see which one gets you the red protect light, then find the short for that speaker/rca wire. if the red light turns on with only the 12volts/remote/ground, then the short is in the amp.

Amp


I honestly don't have a solid answer for you. I can say check your fuses. Check your battery to amp wire. And also check your ground. Make sure the fuse on your amp is also not blown

Low Voltage Post


The head unit doesn't need to be replaced. It can be repaired if the shield is open.

If the amp still give an indication of low voltage and the voltage isn't too low, the amp probably has an internal fault.

V12 MRV-1507 or Xplod? Amplifier - XM-ZR1252 good quality sound


Alpine is just a better brand in general. I have the older MRV-1507, sounds GREAT, i have had friends who has had the Explode line, but it was always a temporary system until they got something better, like the alpine or kenwood.
