One positive (+) Two negative (-) Wires 2 amp (Question)

[5t4y_50L0]

So I have one positive wire to a distro block and sub amp 0 awg and one component 4 channel 4 awg.

I then have a negative distro block one 0 awg to amp and one 4 awg to 4 channel, but I then chose to run two 0 awg from ditro block to chassis. Is this okay or am I offsetting the electrical ?

I also have a fuse distro block with 16 awg power and neg, pos connected to positive distro with sub and 4 channel, neg to separate chassis 16 awg. To the fuse distro I have two Loc, one for sub and one for 4 channel. Should I change something.

Voltage is acting funny the past month, factory ground on battery keeps corroding and when I shut or roll down windows the voltage skips down a split second

It sounds like you're dealing with a complex audio wiring setup. Here are some pointers regarding what you've described:

1. **Distro Blocks**: Having both a positive and negative distro block is standard practice in car audio setups. Connecting two 0 AWG wires from the negative distro block to the chassis can actually improve grounding. Just ensure that they are securely attached to clean, unpainted metal.

2. **Wire Sizes**: Using 0 AWG for high-power applications, such as a subwoofer amp, is appropriate. The 4 AWG for the 4-channel amp should also be fine, assuming the amp's power requirements fit that gauge. Ensure that all connections are tight and that there are no signs of corrosion on terminals.

3. **Fuse Distro Block**: The use of a 16 AWG wire for the power and ground may be too small for a serious audio system. Typically, for LOCs (Line Output Converters) and smaller power requirements, 16 AWG can suffice if the total current draw is low. However, ensure that these connections are not the weak points in your setup, especially with a larger system.

4. **Voltage Issues**: The symptoms you describe—voltage dropping when rolling down windows and corroding battery grounds—suggest that the factory ground may be faulty. Corrosion can lead to high resistance, which can affect voltage stability. Ensure that your battery and chassis grounds are clean, solid, and well-connected. If needed, consider adding a dedicated grounding point for your audio system.

5. **General Recommendations**:
- **Inspect Ground Connections**: Check your battery ground cable for corrosion and clean it up. If it’s not tightly connected or is severely corroded, consider replacing it.
- **Check Loose Connections**: Any loose or poor connections in your wiring can lead to voltage drops and erratic behavior. Make sure all connections across your system are secure.
- **Upgrade Where Necessary**: If you notice a continued voltage drop or other electrical issues, consider upgrading the wire gauges or consulting an expert to evaluate if any components need to be replaced.

If these suggestions don't resolve your issues, it may be worth consulting a professional car audio installer to assess your system in person.

Thanx, so, it's pretty basic, 2 amps and 2 LOC, 1 fuse blocks for LOC and 2 distro fo amps.

I did some troubleshooting and turns out a wire was touching my 4 channel amp, causing the voltage to raise and negative terminal to corrode.
*So I think, have to wait out the corrosion but the voltage now is regular 12.5 area.

I can assume it was a wire somewhere touching my negative wire to the 4 channel.

Thanx again for the help I also got 2 knukonceptz ultra V2 battery post and love them. Most of my accessories are knukonceptz, respect the quality products

Awesome problem. The window switch needs more power to roll down the radio. So more volts heads over to the door switch, taking power from the amplifier and causing it to skip and with less volts going to it. Use all the same wiring gauge. All different ampere ratings for the setup. Wiring gauge. Try to make it all uniform or the same. The alternator will take on the load to recharge the battery. They call this power distribution differential inputs to the amplifier and radio. So the alternator needs to be a good one too to keep up with changes in volts. You don't need to make adjustments to ampere rating or volts to the radio or amp or speakers or door switches. Radios are OP AMP circuits. The circuits automatically re-adjust to changes in - or + signals at the transistor level. In other words, the inputs from the car battery into the inputs of the circuits has a high input impedance. Very high. That means it resist any changes to volts or amps in the circuit in the car when changes happen. So make the wiring all the same.​

Thanx again for the break down, I am fairly new to the car audio world, so as of now I'm thinking of disconnecting my 4 channel amp from the distro blocks and connect it directly to the battery (yellow top) ground and power.
