2 Amp 3 Sub. 1 Mono 4 ohm, 2 stereo 2 ohm
 

1st post.

I have an issue. but for simplicity I will start with the equipment so you know what we are working with.

2 Rockford Fosgate P2 subs. 12" dual voice coil wired for 2 ohm

Autotek M3200.2 2 channel amp.

Autotek M1600.2 2 channel amp.

I have a stereo RCA output for the subs going into the M3200.2. I want to go from that amps output to the M1600.2 amp input.

Heres the problem. In the instructions to the amp, it says Quote, :

"A MONO signal source is required, such as would be available from the mono sub bass output of an active crossover, whether stand alone, or built into a head unit or equalizer. Important: Do not be tempted to connect the hot, or positive outputs, from any source together to obtain a mono signal, as this could very well damage the output stage of that source. It is necessary to feed the SAME signal to both left and right inputs via a Y- adapter RCA cable. Connect the mono speaker positive terminal to the LEFT +, and it's negative terminal to RIGHT -.

My question then is. How do I connect the output from the M3200.2 amp to the input of the M1600.2 amp? It doesn't seem like they want you using the stereo RCA cable, or taking a Y from both L+R output to another Y going to the L+R inputs, but I still want to bridge the second amp.
