How To Install a Powered Subwoofer to a Factory Stereo – Steps

Select a Speaker and an Amplifier

Before a speaker or amplifier goes out or heats up, it can only function at full power for roughly a minute. The RMS rating of your subwoofers should be taken into account rather than the peak rating.

The Vehicle’s Battery Should Be Removed

The most critical duty you’ll have to complete is this one. It is, after all, about your safety. If you overlook this problem, nothing will operate correctly.

Disconnect the speaker’s cables

Unhook the cables from their appropriate ports or terminals after disconnecting and turning off your vehicle’s primary power supply.

Determine The Relevant Links

Connect the LFE jack on the receiver to the output port on the subwoofer box. Use the supplied hole to attach the jack to the port. Look for any linkages that could be crucial to this connection procedure once you’ve established all of the output ports.

Run Wires

Begin by plugging in the battery. Run most of the power wire through the firewall hole, leaving enough for the battery to reach. Remove the insulator from the end of the wire where the battery is installed. Look for a crack in the vehicle’s firewall.

Run the remaining wire beneath the vehicle’s carpeting or, if one exists, through a wire channel. This wire must be sent to the trunk. The in-line fuse should then be connected to this terminal.

Reinforce The Connections

Next is to tighten the connections by connecting the subwoofer’s negative wires, whose source is the sub box, to the left speaker (-). Connect positive wires to the (+) speaker on the left.

Plug-In the Battery Power and Connect the Speaker Cord

Attach a speaker cord to the Subwoofer with caution now. Finally, reconnect the power wire that was previously disconnected. You should now have the signal from your OEM stereo.
