Factory HU vs Kenwood
Forgot to mention that the system will pull around 200Amperes at full load. This based on the fuse ratings of the amplifiers. This means 4AWG or even our special 25mm2 thick power wires wont be enough. Thus we upgraded to Kicker 1/0 AWG power wire kit which can handle upto 3000W system.
Those wires are really thick and extremely flexible.
This would also mean the big 3 upgrade in car audio should be performed
Add thicker Ground wire from battery to the chassis
Add thicker ground wire from engine to chassis
Add thicker power wire from Alternator to battery positive terminal.
Fortunately we noted that nissan has already installed 1/0 AWG wires for the alternator but total skipped on battery wires.
So we upgraded the negative battery terminal and added the 1/0 AWG wires for the body from the battery and 25mmsq (3 awg) wires from engine to body.
This is more like a grounding kit you would you for electrical improvements.
The engine compartment.
The 1/0 AWG wire as the negative terminal to body.
The 1/0 AWG wire, 25mmsq wire and Kicker battery terminal
Heavy duty soldering and insulation
This is where the negative wire would be mounted
Sand paper and elbow grease
