Amp help

[MURDOUGH]

So I have a Pioneer GM-D8400 going to two 12" kicker Comp R subs. When I connect the speakers it goes into protection mode and speakers play like a heartbeat. It's odd. I measure the DC Volts and got over 14, I rewired them with a new fuse back down to 12.2. I can't figure out what's causing this. Please help

Is the amp stable at your ohm load

 

[MURDOUGH]

Yes my amp put out 600 watts for 2 ohms and my speakers handle 800 each

Whats the subs model #

 

[MURDOUGH]

The subs can be switched between 4ohm and 1 ohm each.

These are the subs Kicker 40DCWR122 Ported enclosure with dual 12" CompR subwoofers at Crutchfield.com

And the amp GM-D8400M - Class-D Mono Amplifier with 1200 Watts Max. Power | Pioneer Electronics USA

Do you have them set to 4 ohms or 1 each?

 

[MURDOUGH]

1 although I have tried 4. I've tried them connected together and apart on each setting

Do you know how they are wired inside the box? Check the ohms with a dmm. Is the box wired for a 2ohm final imp?

 

[jrdnhsnbrg 10+ year member]

Set them to 4 ohms, it's harder to mess it up that way.

 

[MURDOUGH]

Yes it is intended for a 2ohm. The wiring in the box has them currently with one positive wire connected into the first speaker and then connected to a second which is run to the second speaker. This is the same for the ground although it runs from the second speaker to the first

post pics of wiring, also what are the speakers running off? hopefully not this amp too lol. whats your lpf set too and i'd say you have the subs wired up incorrectly for that amp (just a guess). i'd say they are duel 2 ohm kicker compVR's
