How to Hook a Home Theater Sub to My Truck Radio

Truck stereos have come a long way over the years in their offerings as they are now indistinguishable from car stereos. Oftentimes your stereo is the prize possession of your truck's interior; but sometimes truck stereos and car subwoofers that accompany them simply do not deliver the bass -- you want to hear in your music of choice. Home theater subwoofers push nearly 10 times the power of car subs and can increase your bass output exponentially, if done right.

Use your home audio subs with your truck stereo for added bass.

Step

Purchase a low-wattage amplifier from your local stereo equipment store. The amplifier does not need to be expensive, as its purpose is to supply a minimal amount of power -- compared with the capacity -- to your home theater subwoofer.

Step

Unscrew the housing assembly for the plug adapter on the home subwoofer unit.

Step

Remove the electronic interior parts from the housing unit; carefully cut the speaker wires for later use. Cut the power cord and dispose with interior parts no longer needed.

Step

Secure your new amplifier in place with screws to the interior housing (wood) of the subwoofer.

Step

Connect the wires attached to the speakers to the amplifier. The positive wire will attach to the positive channel; connect the negative wire to the negative terminal as you would with a battery.

Step

Run your amplifier wiring to the front of your truck. If possible, hide the wiring under the carpet or under the side molding.

Step

Connect the RCA plug to the receptacle end at the back of your stereo.

Step

Turn on your system and test your connections, ensuring the subwoofer works before putting your dash back together.
