My amps blue light is flashing and wont power the subs

This means it is blown. Whenever the power light flashes on any amp it is blown or something else is wrong with it. Most likely its blown. You can blow am amp by hooking it up to a powerful sub and blaring it, or just overheating it. Hope this helps. This can usually be fixed as well

i have a hcca 25001 amp need to know what is the blue and yellow light stand foron the amp and is a both of them need to be on

ITS IN PROTECT MODE. EITHER ITS BLOWN OR THE SUB IS TRYING TO PULL TOO MUCH POWER. UNHOOK THE SUB AND SEE WHAT HAPPENS IF THE LIGHTS STILL BLINK THEN AMP IS BLOWN. IF THEY STOP BLINKING AND ONLY ONE STAYS ON THEN LOWER THE SETTINGS ON THE AMP AND TURN THE BASS AND VOLUME DOWN ON THE DECK TO LOWER THE AMOUNT OF POWER BEING PULLED FROM THE AMP.

My best guess is that it would be your ground wire or even the power into your amp. I would check all the connections going to and from your amp

flashing light could mean a few different things. 1- constant power may not be there. check with a test light or multimeter. should read around 12 volts. it would be a good idea to check all the power and ground leads. make sure u have a good ground. 2- bad sub. im assuming sub since its a monoblock amp. you can meter the subs. make sure the total ohm load is no less than 2 ohms. any lower the amp will go into protect mode. 3- bad amp. power supply may be bad. the newer pioneer amps are full of protection circuits. ive been a professional installer for a shop about 8 years and we sell pioneer. hope it helps.

The light flashing usually means there is a short somewhere. Check your wires to make sure there are no slices and are touching. Also check to make sure you have your remote wire hooked up.

If you have a voltmeter, check that you have 12V at the power connections and also that you have 12V at the remote turn on terminal. If this is all OK, be sure that there is no short in the sub box cresated by something loose. If this is a sub that you take in and out with quick connectors (like the kind you push down and then insert the wire into the hole) be sure that there isnt a strand or two of stray wire shorting the terminals on the outside. If all that checks out, you most likely have a bad amp.

are you sure its not PROT?
the amplifier is protecting itself from fire because of something.
Disconnect the subs. and turn on.
if it comes on normally, the subs are at fault and will need attention. If the light still stays on, you hafe probably blown an output on the amplifier and it will need repair.

The person(s) who hooked up your system made a boo boo. They wired your remote turn on lead to the power antenna lead instead of the amp turn on line (both are blue and easy to mix up). Thus when your radio is on it sends a signal to the amp and the amp turns on, but when you set to CD the signal goes away and your amp shuts down. Easy fix, just re-wire the amp turn on lead and the problem will be fixed.

I think the blue wire is a standby "on" to be hooked to separate or system switch. Without knowing how you have system wired, I can' offer much. A bit of caution; having a thousand watt amp hooked to 6x9 dooms their fate
