I have identified the two + 12V cables with the DMM now I know which ones are at 8A and at 14 A
to power the radio I'm using + 12V 8A
are they enough or should I use the 14A one?
(at the moment the radio turns on and it works)

so you need to connect all the yellow cables and then put a 25A fuse with an AWG8 cable?
(since for the radio it is sufficient to use the 8A one)
if I connect the yellow cables the power supply to the radio must come from the biggest cable AWG8?

the other cables (red, black) I have to connect them together or I leave them free?

connecting the various yellow + 12V cables I would not have the sum of currents above 22A since each cable carries respectively 8A and 14A
(example sum 4 yellow cables all from 14A I get 14Ax4 = 56A)

      View Listing Sony ES XM-5046 4 channel amp Made in Japan
      Sony ES XM-5046 4 channel amplifier amp (old school, made in Japan when Sony was good)
      60x4@4 ohms
      100x4@2 ohms
      180x2@4 ohms bridged

      They are 1 ohm stereo/2 ohm mono stable. I have read in several places that they will do over 300x2@2 ohms bridged. They have dual built-in cooling fans and a pretty small footprint.
      The end cover screws are getting stripped but are still usable, and there is a small bit of corrosion on the bottom corner of the frame as seen in photos. Nothing to be concerned about IMO.
      $100 shipped CONUS.

      View Listing Crescendo BC5500D
      Stable down to .5ohm on strong electrical.
      Up to 18.5v capable.
      5800watts @1ohm on 13.8v
      Had the amp sitting in my room unused for about a year, needing to get rid of it. Now I'm finally selling it. They just discontinued the bc5500 for the new 6k. They're sold out.  If you know crescendo, you know they mean business! And the bc5500 has been ran by many well known/respected competitors. Overall great amp, tons of power. Had no problems running. Always had good electrical running to it. 
      Cosmetic: 9/10 pretty much 10/10 not much, if any, scratches 
      Performance: 10/10

      Okay so basically don't have a lot of knowledge about car audio systems just want my car to be obnoxiously loud.  I have a 4 channel amp, 4 speakers and 2 subs.  Can someone direct me to an installation guide to make it easier.  Also is it possible to have all 4 speakers and 2 subs hooked up to 1 amp or hook 2 of the speakers straight to the headunit cheers
