Home theater sub-woofer in my car?

Yes it could work but the main thing you need to look at is this. Any type of electronics that you plug on your home is AC (alternating current) and vehicle use batteries which are DC( direct current) so check your amp becuase it might be AC which will not directly connect to your car but could work with a power inverter. I am not familiar with the setup you want to use. But there are some eletronics out there that use AC and have built in converters to go to DC things like cell pnoe chargers and cordless house phone for example so your amp may very well be DC. Thats the only bump i see in your plan other than space constraints. Speakers are speakers and that doesnt matter.

this one best for u. Infinity Basslink 200-Watt, Dual 10" Powered Subwoofer System (Black) Technical Details * Powered subwoofer with onboard 200-Watt Class D amplifier * Variable electronic crossover (50Hz to 120Hz), sensitivity, and bass-boost * 10-Inch subwoofer and 10-inch passive radiator * Variable Bass EQ (+3db to -6 db at 45Hz) * Includes Basslink LC remote bass-level control

i installed a power inverter from harbor freight in my trunk and used a home theater sub bridged off my audio, sounds great lots of bass response i even got it to all switch from my dashboard!

ok these people are idiots, larry an mr wake up are absolutly right on what they said. the one guy that said "a speaker is a speaker" is 100% dead wrong , a home speaker an an audio speaker is completely diferant no matter what size or brand they are, the power an ohms are dif an even though it may work an produce great or shitty bass it can an will damage your amp,subs,head unit ect.. that a/c, d/c thing will work for the power supply prob but still not a good idea. next every subwoofer has its own specs for a box its suppose to go in which is where the air space comes in. even though the sub hits it has to have enough breathing room an air to get the full potential out of it... next, sound travels so like the other guy said if you have a sub in a big room an than in a small space things get in its way an wont travel like its designed to do{hence the differance between house speakers an audio speakers} you ever see a system in a car where the sub is mounted backward in the box???? its not just for show my man its designed like that for a reason, try hookin up a home sub in a box backward like that an let me know how it sounds...ill tell you its gonna do nothing but pop an blow faster than you can say OH ****!!!! anyway man you best bet is to listen to me an the outher two guys i said above . so even though your idea may work an sound good or bad its just not a good idea you will end up spending money on replacing subs,amp,head unit. keep the home stuff in the house an use the car audio for the car because even if the home stuff may sound good in the car, the car stuff will always sound better in the car an you will spend less money an less time tryin to figure out how to get you home stuff hooked up in your car. trust me!!!

I guess it could be done, but I think it's a waste of time and money. The amp voltage is wrong, and while there are step up converters for power I think you are asking for trouble. Car stuff is designed for cars, and home for home. I have no idea what the impact of bouncing around in a vehicle trunk may have on home equipment - and it's an expensive way to find out! I would sell the sub on E-Bay and use the proceeds to buy a proper car amp/sub and box - car subs are usually much cheaper than home subs anyway, so you may even have some money left over ;)
