Protection light won't stop blinking/ Subs don't work

Just installed this amp into my car. I know that nothing's blown because it has worked for a few minutes. But now everytime I turn my car on the protection light justs blinks and I get nothing out of my subs. Wiring is all good, everything is brand new. Any ideas would be helpful.

    Read through the troubleshooting guide, it may have something to do with the RCA's or Speaker wires. Tested this by taking out the rca's and speaker wire (sub amp powering 2 12's) when I turned my car to aux, instead of blinking the protection light was just on, no blinking. I then re-attached and they started blinking, took them off again with it on and it stayed blinking, weird. Also, put a voltmeter across the amp (power and ground) when the prot. light blinked off it showed 12~ volts, when the prot. light blinked back on (protection on) the voltage would drop anywhere between 1 and 3 volts, going as low as 9.5~ volts. Does this help? Is there more info that I could get that would be helpful?

The amp probably has shorted output transistors to eliminate other possible causes, read through the following page. Let me know if you have any other questions.

My ripspeed incar dvd player has got no picture but has got the sound what can i do to make this work

First thing comes to mind is a possible update to the system. Have you had it for a while now? If so, you should go to the computer and go the maker of the unit. Check under software updates or downloads to see if there has been a remedy or fix that the maker has published, if so...then do as it says to do and see if this resolves the problem before you get into the actual technicals of the unit. It may need nothing more. I hope this helps.

All you can do is trace the wiring back from the radio to the speakers, there is no quick fix here. To test the speakers touch a battery to the two contacts, the speaker will pop if it is any good.

Lightning audio b150.2 as soon as +12 is hooked up blows 25 amp fuse and the c2 1000uf/35v capacitors blow???????

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.

RCA cables are the best way to get the audio from your head unit to the amp. If your head unit doesn't have RCA outputs, you might be able to use the speaker outputs of the head unit to connect to the "high power" or "high level" inputs of the amp, if the amp has such inputs (check your manual).
