Sorry for the stupid questions but i dont want to screw up. I have a 600 watt, 2 channel amp that i want to bridge to one channel at 4 ohms to power a sub. Im running an 8 guage power cable down the passenger side with an inline 60 amp fuse about 12" from the battery to the power terminal on the amp. Then i am running the RCAs down the drivers side with the remote wire but I'm not sure what to hook the remote wire to on the headunit. I have an adapter on my factory harness to fit my after market radio and from the wiring side harness (connecting factory harness to new harness) i have a blue wire. Is this the wire i am supposed to use for the remote? I also have an unused blue/white wire coming from the back of the radio harness that says "system remote control" Which one do i use? Also how do i bridge my two channels into one? thank you so much

 

Ok i just used a test light and found that the "system remote control" wire gets power when the radio is turned on so is that the remote wire i am supposed to use? Thanks

 

Please help someone must be able to tell me how to bridge two channels to one and if that is the right wire? Please....

 

if the wire gets power when the HU is on then it's the right wire.
If you want to bridge 2 channel into 1, be sure your amp is capable. If it is, then it should have marking on the speaker out terminals. Good luck.

 

600 watts use power cable & ground cable 4 gauge is the right way.
