Battery relocation with car audio

[DGajre777]

My stock battery finally gave out yesterday. Since I haven't found any info on people with car audio, here is a my wiring schematic.

Questions:
1) Am I okay to run a 4G wire for the alternator or do I need to upgrade to 2G or 1/0G? I already have a 4G wire from the alternator to a 100 amp ANL fuse on the firewall.

2) How do I incorporate a 4G wire for the amp? Should I run it directly to the battery or mount another distribution block?

3) Is the wiring for the toggle switch with a 10G wire correct? I don't want someone to be able to kill power to the battery while the car is parked and the alarm is on.

Any suggestions on the wiring?

Have you had issues in the past, or just being overly paranoid?

Maybe apply a healthy dose of red threadlocker instead of welding.

No issues of it coming lose yet, I just prefer things to be overly secure so I don't run into a "what happens if" scenario. It's a pilot thing!

you have 2 x 12" polk momo's? Those subs are DVC 4-ohms correct?? well there is no way to get 2 x 4-ohm DVC subs down to 2-ohm.....one DVC 4-ohm sub bridges to a 2-ohm by itself, bridge it with another and it bridges down to 1-ohm, series the two and it goes back up to 4-ohms.

If you inded have two subwoofers that are both DVC 4-ohms, theres no way to get both to 2-ohms together.

This represents two polk momos in series, if yours are bridged you have ~1-ohm, which is not good for your amp if its unstable at 1-ohm,

that would be why it shuts off

With your subs, this site here shows your only options.

its already setup hit view wiring options

here are your subs,

which inded are DVC 4-ohms, meaning each voice coil is 4-ohms,

Never mind, I just checked... the Polk Momos aren't DVCs, they are SVC 4-ohms, wired similar to this, except I have the 16 AWG speaker wires from the subs going into the amplifier speaker connectors.

awesome, scared me for a second, yeah I usually use 12ga speakerwire.

I'll try that too!
