Why is my amp going into PROTECT

[SLIPKANOT 10+ year member]

I got 2 Alpine Type Rs (Dual 4 Ohm). I got em wired down to one ohm. my meter confirms that its one ohm. My 500 watt Memphis Mono is one ohm stable also. When Im listening it will randomly go into protect. i dont believe the wires are shorting anywhere. my only thought is that my voltage is dropping too low at certain frequencies. any suggestions will greatly be appreciated. Thanks

What's the model # of your Memphis amp?

Im hitting like 11 usually when its really slamming. i think the minimum on the amp is 10

Im not sure what the model number is. its an older Power Reference Amp. i got it for 30 bucks. the guy thought it was blown but it was not and i got a steal

Well if its going into protect, that might be the reason he thought it was blown.

I suggest turning your gain down slightly. At the very least keep your voltage above the 12.0v mark. Anything below that and you really start running the risk of breaking something

11 is pretty low. Is the gain up too high? Could be blown too

There has to be something wrong with that amp. I just cant see a 500 watt amp dropping your voltage that bad unless you drive a yugo.

Could be a crap alt

Could be. But from his OP, seems like the original owner of the amp was having the same issues. Thats why he thought it was blown. Plus those old Memphis amps were notorious for going bad.

Could be horrendous/tiny wiring or insufficient grounds.

The amp just started doing this now that im down to one ohm. i rewired from my amp to my subs and now its not doing it anymore. i believe where the wire connects to the terminal on the box was shorting sometimes. Also my wiring is 4 guage all the way to my amp from the battery. my ground wire is very short and is also 4 guage. I have a capacitor which is frowned upon by some but it helps alot for me.

I am on my stock Alt. but it seems to be doing fine. In week i am upgrading to a 2000 watt Hifonics amp. its one ohm stable and its pretty nice. ive seen it in action and its a great match for my type Rs

If your electrical can't handle 500 watts how do you plan on running 4 times that power?
