    Home Theater Subwoofer

    Can i use a home theater subwoofer in my car?

    It plugs into the wall and i have a power inverter that can handle it. It has input for left/right and an RCA plug on the back.

    I don't know if it will blow anything if i put it in my trunk?

    P.S. i have a 93 chrysler lebaron with stock stereo.<br /><br />

    You can likely use it with the inverter, although it probably won't sound good as the speaker was designed for a much larger environment, and you'll likely have noise/grounding issues related to the inverter that may make it effectively unusable.

    Worth a shot, though, if that's all you have and you don't want to spend any money.

    you sure as shoot can use it

    i don't know how well it will sound, but you definitly can use it.

    just make sure you wire it up into the right channel, that ususally will bive you the best mono sound.

    However, if you have the stock stereo there might not be a sub-out, so you'd have to ask someone else how you'd wire it up.

    The only problem, besides what has already been mentioned, is if you were to use this as stated with the inverter. How are you going to turn it on or off? Car amplifiers are activated via a remote turn on wire. And I believe that Self-power home theater subs are signal sense activation, but they are always on. And in this case, so will your inverter.

    either that or wire the inverter to an ignition wire so that it turns off when the car is off. Just make sure its fused/gauged properly.

    The only problem with a relay or wiring up to the ign is depent on how much current is required to run the Inverter. Potentially a standard bosche relay is only capable of giving up to 30A which equates to only about 4200W@14Vdc or 360@12Vdc. If the inverter requires more juice then multiple relays or higher amperage relays may be required.

    I doubt that his home theater sub draws more than 500 watts or so...usually those home theater sub/amp combos are not "highly powered" compared with car equipment.

    If it does, then simply use two relays.
