Use a distribution block and a fuse for each amp. Share the REM wire between both

How would i run the dual coil with the 4 channel would that use all the channels and also can you run two 6x9'swith a 2 channel amp though!

Mate, I'd highly recommend popping into your local car audio shop and getting some face to face advice. You'll need just ONE fuse right next to the battery. but the sizes of the cables you'll need before and after the distribution block will need to be looked at - it depends on the amps. You may. or may not be able to run the sub on that 4 channel amp. definitely across 2 channels (but that won't offer any advantage over using the 2 channel amp), but you may not be able to bridge the front channels of the 4 channel amp (to use all 4 channels on the amp), not all amps can. A pair of 6x9s will happily run on a 2 channel amp. question is, SHOULD you be. I'd be running front speakers on an amp over the rear speakers. Sounds like the amp will be underpowered for the sub you have. but without RMS rating of the sub, RMS rating of each channel of the amps/RMS rating bridged, the amps Ohm stability per channel, the Ohm rating of the sub etc etc it's hard to give specific advice, and it's hard to give detailed advice like this over the net. Then RCAs can get tricky too if you don't have the right outputs on the stereo

As above, too many factors to get into specifics, ideally you do want a separate fuse for each amp in case one amp carks it and kills the other from a surge. The impedance and voice coil configuration of the sub along with the amp ratings are important to check and match as it could overload your amp.
Yes you can run two 6x9s from a 2 channel no problems

then again most car audio place usually keep that valuable knowledge to themselves as the selling of the install itself is worth alot more in profit than the gear they sell you. if they gave everyone helpful advice they'd loose business.

Where I worked, if someone came in with the right attitude wanting advice etc anyone who worked there would have been more than happy to help. a sale could be made too from the fuse/fuse holder (the normal inline fuse/fuse holder probably won't be big enough for these 2 amps, the larger type will be required), possibly RCA splitters, large gauge power/earth cable, terminals etc. and after all that, the customer may decide they want a pro to fit it anyway. It's just good customer service. and that word would get spread around!
Ive got the sub going but its not very loud compred to old amp mayb im bridging does it mtter if you have the sub on left or right pos neg at tje mo its at rear left and right
