#2 Method: Using Line Output Converters

Line Output Converters

If your car stereo doesn’t have low-level RCA outputs, you’ll need to use line output converters (LOCs). These devices convert a higher-level signal into a lower-level one compatible with most amplifiers. You can find LOCs at most electronics stores.

Installation of the Line Output Converter

Line Output Converter LOC

Installing a line output converter is a simple process. First, you’ll need to connect the LOC to your car’s stereo head unit. Most LOCs will have a set of wires that need to be connected to the head unit’s speaker outputs. Consult your LOC’s instructions to determine which wire goes where.

Once the LOC is connected to the head unit, you’ll need to run a pair of wires from the LOC to the amplifier. In most situations, the wires may run beneath the carpeting to the trunk or engine bay.

Find the factory wiring harness

In order to connect the LOC to your car’s stereo, you’ll need to access the factory wiring harness. This harness is typically located behind the dash. You may need to remove the dash panel to access it.

Identify Wires Color

Once you’ve located the factory wiring harness, you’ll need to identify which wires are for the left and right channels. In most cases, this information is printed on a label affixed to the harness.

If there is no label, you can use a multimeter to test each wire until you find the ones corresponding to the left and right channels.

Remove the insulation

Once you’ve identified the left and right channel wires, use a wire stripper to remove a few inches of insulation from each one. This will expose the bare wire you’ll need to connect to the LOC.

Keep the wires together

Once the wires are stripped, twist the left and right channel wires together. This will ensure that they make a good connection. You can then use a wire connector to secure the connection.

Now you’re ready to connect the LOC to your amplifier. Consult your LOC’s instructions to determine which wires you need to connect. In most cases, you’ll need to connect the ground wire to the amplifier’s chassis and the power wire to the amplifier’s remote turn-on lead.

#3 Method: Using The High-Level Amp Inputs

The High-Level Amp Inputs

If your amp doesn’t have RCA jacks, don’t worry – you can still use it! The high-level inputs on an amp are designed with a factory radio or an aftermarket radio that doesn’t have preamp outputs.

To Use this Connection

You’ll need a set of speaker wires to use the high-level inputs. The amp’s positive input must be connected to the positive wire, and the negative input must be attached to the negative wire.

Attach the cable to the fuse holder

Before making any connections, connecting the cable to the fuse holder is essential. This will ensure that your amp is protected from any power surges.

For easy access, mount the fuse holder near the battery

Once the cable is connected to the fuse holder, you can mount the fuse holder near the battery. This will make it easy to access if you ever need to replace the fuse.

Plug in the speakers

After the fuse holder is in place, you can connect your speakers to the amp. The positive wire from the speaker will need to be connected to the positive output on the amp, and the negative wire from the speaker will need to be connected to the negative output on the amp.

Make sure the ground connection is secure

The last step is to secure the ground connection. This will ensure that your amp has an excellent connection to your car’s chassis. The ground wire can be linked to any metal component on the vehicle.

Check whether the amp turns on after reconnecting the negative terminal. At this moment, you’ll need to start a new preference.


Can I substitute the speaker wire for RCA?

RCA cables are used for both audio and video signals. Speaker wire is used solely for hooking up the speakers. So, if you want to connect your sound system, the speaker wire will do the trick. However, you’ll need RCA cables to connect your sound system to a TV or other device.

Do I need RCA connections?

Although we’re not sure if RCA cables affect audio quality, many experts believe they may. Premium RCA cables are typically made of higher-quality materials and have better construction than cheaper options, providing a more accurate signal transfer. If you’re serious about obtaining the best sound quality, a high-quality RCA cable set is worth considering.

Do RCA cables transmit power?

No, RCA cables were not designed to carry power. RCA jacks were designed to carry signal, not power. If you need to connect a device that requires power, you will need to use a different type of cable. Thanks for reading!
