I guess this really should go in the amp forum but it appears this one gets more traffic. I just install 2 10's in my friends mustang. We're pushing them with a Pioneer amp, not sure which one, it's an 800 watt amp. At loud volumes and occastionally not too loud, they'll cut out. What would the problem be? Gain isn't turned up very much.

 

Where is the amp mounted? It sounds like it is overheating. Also, check your wiring to make sure you have the speakers wired properly.

 

My amp was getting over worked, and would clip the signal and cause the sub to bottom out, but not cut out. Hmmmm. Put your hand to the amp, Is it hot as hell?
Could be in the wiring of the subs as indicated.
My amp was clipping because i had the Bass EQ CRANKED, but you said you dont have the gain cranked?
odd

let us know what you discover

 

Do you have the speaker wired in parallel off of one channel (bridged) on the amp? It might be overloading the amp and a fail safe is tripping. If you do have them wired that way try disconnecting one of the subs and see if it still does it. It could also be a wiring problem (like a short) or overheating. Look through the manual for the amp and for the subs and make sure everything is hooked up right and not overloading it. Without knowing more about the amp/subs I'm pretty much just guessing.

 

Yeah I have the amp bridged, I guess that's all there is to it. I'll have to see if it still does it. I know it isn't over heating because it happens as soon as 2 minutes after turning it on.

 

I don't know the specs on your amp, but I would have to say your amp is probably not 2 ohm stable in bridged mode. Does it go into protect mode after a few minutes. Amps don't overheat very easy for no reason. Check the specs for the amp make sure it is 2 ohm stable bridged.

 

Off the top of my head, I'd say that none of Pioneer's amps are 2 ohm stable BRIDGED.

Too low of an ohm load (improper speaker wiring) is likely your problem.

 

The amp is a bridgeable amp. How should I wire it to bridge?

 

Some amps have different ways of wiring bridged. Mine is to take one of the positives from one channel and one of the negatives from the other channel and then push in the mono button. I have seen some that have a totally different hook up area for brodged mode. Best to consult the manual for that amp.

Also, most amps that say they are 2 ohm stable will drive a 2 ohm load in 2 channel. Bridged it will only drive a 4 ohm load. Some thing about the internal resistance of the amp is halved when it's bridged so when you put a 4 ohm speaker on it, the amp registers as a 2 ohm load bridged. I don't understand it completely, so I can't go into detail.

 

I found out part of the problem. I let a buddy run the ground wire and he didn't tighten it very well. When the amp hit really hard it would rattle the wire loose. I still think I need to unbridge the amp though.
