Leave it alone for about 4-5 minutes...and see if it comes back on. That would solve the problem if it was going into thermal protection. If that doesn't do it you need to check all of your wiring because you more than likely have a short somewhere or the amp is going into protect because of an impedance that is below it's capabilities. BTW, you should have posted this in the Car Audio Discussion part of the forum instead of the review section...
**moved** I placed it here because it is a tech question, not a review Jay, let's figure out the problem here. A forethought... did it instantly go into protect, or have you had it for a while? When does it go into protect? Does it go in when you begin to set the gains, or is it immediately? If the system has been in place for a while, did you begin hearing signs of audible stress from the subs, such as scrathcy sounds, uncommon distortion, clanking, clicking, rapping etc? Now let's help with a quick dose of basic diagnosis... First, I suggest removing power from the amp for a few minutes (remove the inline fuse). While the power is off, look for any stray strands of wire crossing the terminals, both at the main power/remote power/ground point and the speaker terminals. If you find something crossed there, correct the issue. Also be sure to check that the amp is properly wired (+ to + and - to -). I suggest this because some amps require the power to be removed for a few minutes before resetting. While you are resetting the amp, look for the obvious and correct the issue. If you still go into protect... Remove the subs from the amp if you still have an issue. Be sure to perform the reset procedure I outlined above (remove the inline fuse for a couple minutes) after you remove the speaker wires. If the amp falls out of protect with the speakers removed we need to know what subs do you have, what is the voice coil configuration (SVC4 ohm, DVC2 ohm etc) how are the sub(s) wired? (take a pic of the subs out of the enclosure and how they are wired if you need... attatch them here or e-mail them to me, I will host them). look at the binding posts of the enclosure to be sure no speaker wires are crossed or stray strands contacting the terminals incorrectly. Now remove the subs from the enclosure. When you remove the subs from the enclosure listen for unusual noises (like a slinky, or a clank) and look for obvious signs of physical damage to the woofer (like seperated coils, broken tinsel leads, etc). Also, look here again for stray strands of wire, etc... After trying these things, drop in here and report. What I am trying to do is narrow the problem down to where it is occuring, then we will attack why it has happened and correct the issue.
Seth, you're a post whore...Obviously, Krelkor's mom told taught you some of his tricks Anywho, protect mode can occur for many (obvious) reasons: As Seth mentioned, check the wiring of the subs...you may very well be sending that amp a load it's not rated to handle (2 ohm amp sees 1 ohm load and goes into protect...). I don't know the specifics of that amp, but that's something that should be among the first things you look at. Also, check both the ground (for absolutely clean contact, and a nice, tight connection) and the wire guage. If your using too thin a wire, it's like ramming a jackhammer in a keyhole. Check the power wire at both the amp and the battery. Make sure it, too, has a solid connection to the "connector"/ring terminal. Also, and Seth might remember my post on CAF, make sure the crimp is rock solid. I had a loose/weak crimp and it took almost took my system down. Sometimes it's the most obvious things that put a crimp <_< in your getup. Another blaringly obvious thing to check is amp ventelation. If it's crammed under a seat, or mounted upside down, or just plain doesn't have room to breathe, it might be overheating. In short, check all connections, wires/cables, and ventilation of the amp. Usually, it's just a common "lookover" and the problem is easily remedied.
Damn seth! How on earth do you make such a long ass post diagnosing amp protections?! Ummm, sure this isn't Geo posting for seth? :no: Last time i had an amp that remained in protection, the power supply had gone bad, and i couldn't keep a good fuse in it. Make sure your amps fuses haven't blown. If they have, replace them. BUT WAIT! Before powering up your amp, run through everything told to you by those smart fellas up above, they are absolutely correct. Now, if all is fine, power it up, and see what happens. If it goes back into protection, and the fuses blow again, you have a bad amp.
Yeah, and I just had another birthday pass me by . Just being thurough man, why leave the guy in the dark?
