amp works with 1 sub and not 2

So here's my setup:

Audiobahn a8002T200.0 Watt - 4.0 Ohm - 2.0 channel(s) 400.0 Watt - 2.0 Ohm - 2.0 channel(s) 800.0 Watt - 4.0 Ohm - 1.0 channel(s)2 10" JL 10w-1 4 ohm single voice coil125watt RMSPorted boxNow that all of that is out of the way. Here's way happens. hook each sub to each channel and the power light will continually fade out (along with sound) After a few times of this it'll eventually cut off and then turn back on and the sub will shoot out and then th protection light will come on. hook 1 or 2 bridged............ same thing..hook 1 to 1 channel and it works perfectly. Any suggestions? TIA

You said hook one to one channel and it works. Did you mean to say hook one to either channel and it works? Have you checked voltage getting to the amp while it is trying to play?

what guage wire are you using?

did you try it 1 sub to 1 channel and the 2nd sub on the second channel that should give you the right ohmsDustin

try them in series-parallel
