sub and amp problems
 

Recently installed a set of pioneer 10 inch 4 ohms subs in my car wired up to 2 ohms mono and hooked to a rockford fosgate 500a2 amp but when u turn up the volume the protection comes on in the amp for about 3 seconds than music comes back til u turn it up again ...... this amp is made to run 2 ohms mono but just to prove it wasn't the amp I also hooked the 2 pioneer subs up to a kicker 600.1 amp which is also 2 ohms stable and same thing , when you turn it up the protection comes on i nthe amp til you turn it back down.
I tried it in 2 seperate cars both with 4 guage wiring , plenty for a 500-600 watt amp. I don't have any other subs to chuck on to test so that way would cost me money . I am looking for your ideas on what is causing these amps to go into protection running these subs. Both amps fine at 4 ohms mono as loud as u wanna go and the rockford at 2 ohms stereo . . . but 2 different amps having the same problem is kinda odd ? If you can offer any help please do :)
thx

Its 2 ohm stable per channel, not bridged.

ahhh
 

the rockford fosgate 500 a square is not a bridgeable amp ?

rockford punch 500 a 2 Specifications:

125 watts x 2 @ 4 ohms continuous power

250 watts x 2 @ 2 ohms continuous power

bridged - 500 watts @ 4 ohms

(Underrated!!!)
ok that solves that amp but now how about why my kicker kx 600.1 won't run them without going into protection mode at 2 ohms ?

because its only 4ohm mono stable?

serious ? the kicker KX 600.1 is only 4 ohm stable? that can;t be ....... 600 watts rms into 4 ohms?

aint the mono KX down to 1 ohm stable far as beeing only 4 ohm stable wtf? no


Amplifier output impedance / channel 2 Ohm *************

Maybe you have it wired wrong?

wire check
 

I have the positive and positive from each sub wired together into + on amp and same for neg. and the box is right as well when i test with an AA battery to find + and - I get them right , when + of sub is on + of battery and i touch it both subs go out so its not that , and like i said i have the rest done right I been into stereo stuff for years.
4 guage power wire , 4 guage ground wire and its all nicely sanded and bolted down to the car body , 22 guage remote on wire from the back of my clarion deck and bassworx 40.00 rcas run from the front to back of my car.

Are the subs single or dual voice coil ?
