How would i go about wiring 2 4 channel amps, each to one sub. for example, which one connects to the remote., or do i have to splice it so they both do? thank guys

 

I would really recommend buying a sub amp. The JBL 600.1 can be had for well under $200 brand new. But if you must...... I'm not sure what subs you have or what impedence the voice coils are.... but I think you should use 1 whole amp for the subs and power your other speakers with the other 4 channel amp. Bridge 2 channels together for each sub. Caution: Your amp may not be able to handle this load! Like I said, I don't know what subs you have but once you bridge an amp you usually have to use at least a 4 ohm load..... some sub amps excluded... but I'm pretty sure with any 4 channel amp, a 4 ohm load is going to be a must. The remote wire? If your only running those two amps, just splice it into two.
