Question about Infinity Reference 1211a Car Audio Amplifier
I had my Infinity 1211a mono amp hooked up to my 2.1 fared cap and 2 Infinity 12" subs and the amp worked for about a week untill it gave out and the protect light started flashing off and on and making a ticking noise while flashing unrhythmically... I left it all hooked up and occasionally the subs would kick on for a couple seconds right when my vehicle was started up but would die after that. Now the subs don't even kick on at all - not even for a couple seconds - but the protect light continues to flash. HELP PLEASE!!
Check your capacitor carefully(and connections),check your 30A fuses,u should have 4 guage wiring,if not that, pull your subs out the box, check the terminal wiring because they like to burn up before the voice coils.The coating will burn and crumble then the Small copper wire will burn up.

Yes make sure your powers and grounds are all ok. If you have round glass fuse in the power wire replace it even it it looks good. Ive seen those fuses melt the solder internally so they will be "blown" but look as if they ar eperfect.... if that does not help your amp needs repaired. go to my website at http://home.comcast.net/bigmikeselectronic/repair for more info. I may be able to repair it fo ryou or buy it form you as-is...

This problem sound like you have too low of power going to your amp, test your battery and make sure its putting out enough power for at least the mininum amount of power that your amp requires, you can find that information in your manual or sometimes they post it on the amp itself. i hope this info helps
