Amps And Speakers

[Guest elation2]

hi i was wondering if any one could help me.

i have got two amps, 4 6x9s and three subs.

ive got one amp connected up and running with the 6x9s running through it.

 

the questions are:

1. can i put the remote wire (blue cable) from the amp connected to the other one im installing so it will switch that one on too.

 

2. i only have enough connectors two run sound to one amp (the audio cables red and white) because my amp has input and and output audio cable connections could i plug the other amps input audio cables to the output connections of the other amp

 

im using seperate ground cables and power cables cause that simple but i dont wanna have run all the cable through the car again.
