Sure, here's a simplified version:

1. Connect red wire to +12V.

2. Connect black wire to ground.

3. Attach blue wire to switched 12V.

4. Connect speaker wires correctly.

5. Plug RCA cables into inputs.

6. Adjust gain and crossover.

7. Add fuse near battery.

8. Double-check everything before powering on.

To wire in the 4-prong plug on the Alpine MRP-M350 amplifier, you will need:

A 4-prong speaker wire harness

A crimping tool

A wire stripper

Instructions:

Strip about 1/2 inch of insulation from the end of each speaker wire.

Crimp a connector onto each speaker wire.

Connect the speaker wires to the corresponding terminals on the amplifier.

Secure the connectors with the screws provided.

Here is a diagram of the amplifier's terminals:

1: Ground

2: Positive (+)

3: Negative (-)

4: Remote

The ground terminal is the one with the green stripe. The positive terminal is the one with the red stripe. The negative terminal is the one with the black stripe. The remote terminal is the one with the white stripe.

Once you have connected the speaker wires to the amplifier, you can test the amplifier by connecting it to a power source and a speaker.

Here are some safety precautions to keep in mind when wiring the amplifier:

Always disconnect the power before working on the amplifier.

Be careful not to strip too much insulation from the speaker wires.

Make sure that the connectors are properly crimped.

Do not overtighten the screws.

I hope this helps!
