Red LED "Protection Light is on" What is the problem

I recently installed a Crunch BlackMaxx BLX2250 in my car. It played fine for two days and then all of a sudden there was no sound. But randomly it will thump wheter the RCA's are hooked up or not. I've checked all the wires, there are no bad connections. I've even checked the voltage with my meter. Could there be a short in the remote wire? Or does the Red Light mean that the Amp is blown?

The red light means the amp is in protection mode. A few things can cause protection mode..... First disconnect the subs completely from the amp, and turn it on, if it powers up you have blown subs. Also try checking the main power wire at the battery...sometimes the current your meter is seeing is backfeeding from the remote wire, so your main power line could be blown at the fuse under the hood. hope this helps

Does crunch blackmaxx take aux for iPhone?

The amp is a discontinued model, but I do think I found the specs on it. It will produce :
350 Watts X2 @ 4 ohms
700 Watts X2 @ 2 ohms
1,400 Watts X1 @ Bridged at 4 ohms
It is designed to be ran inline between your stereo and a set of, or a single, sub woofer.
This could be a significant amount of work for a beginner in car audio, but it can be done.
I would do a little research and decide if you want to use this amp. Join in on forums like http://www.caraudio.com/forums/forum.php, and http://mobileaudioforum.com/forum/forum.php to learn what can be done, and how to do it. good luck.

My amp is on but the protection light stay's on!!

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If the protect light remains on, the amp likely has blown output transistors.
