Amp wont turn on It's an Alpine PDX1.1000. Bought brand new in Feb of 09. Had it in till winter and took it out. Hooked it up for the first time since the winter. Was working fine, turned up loud a few times and went into protection mode.
No big deal, it's normal for them to do that when you turn it up REAL loud, so I turned it down and it came back on and it worked fine.
Fast forward 15 minutes cruisin down the block...crank it up, goes into protection mode...wont come out...no lights no nothing.
It lights up blue when normal and lights up red if blown or there is something wrong..but nothing at all.
Checked all fuses, ground, power wire, remote turn on, everything. Will NOT come on. Makes a pulsing noise when the remote turn on is connected so I know the connection is good in the dash.
I'm stumped.

With proper power and ground it should not be shutting off. Did you give it a sniff make sure you didnt fry anything? I have three of these amps and as stated above they shouldnt be shutting off on ya
Oh and did you try unhooking the subs? Just a quick thing to check sometimes a loose wire on that end cant put the amp into protection too

No ill check that...had no idea that a loose wire could cause the amp to go into protection mode.

correct 99% of amps have a protection and its for that reason to protect it but you shouldnt be hitting protect on a regular bassis, either its starving for power or being overheated, both will drastically shorten the amps life

It's been a few days since ive posted but it started workin the day after I started this thread. The night it stopped working I took it all out and put it back in the next day. I made sure everything was good with the multimeter and everything checked out ok so I hooked it all up and it started working. I'm not sure if the amp just had to reset or what.
