Help/Suggestions on Wiring

[PortSideAudio]

Hey guys, I'm taking on the task of installing a HDC3.118 in my corolla in a 6 cubic foot box.

So here is the wiring I will be installing (critique as you feel necessary)

• Knu 0AWG from battery to second XS power
• NVX battery isolator
• 4AWG going off XS to Q4-120 and Q1-2200
• Fuse for 0AWG then another fuse for each 4AWG power wire (if I remember correctly the fuses are 250A and 150A)
• Either 8AWG or 10AWG speaker wire (the sub has 10AWG direct leads)
• To amps running coaxial RCAs (I was told Soundqubed uses single input not differential)

Problems I can see arising:

• The box takes up most of my trunk, I will have very little room for amp and battery (amps may have to end up being outside the trunk *thoughts on this?*)
• If you can think of any other problems please tell me

So what I'm asking for:

• General critique over everything above.
• Is there anything major I should avoid doing in order to ensure safety and functionality?
• Do you guys have any tricks to keep this build clean and easier to work with?
