Car sub in-the-home

Has anyone tried using a car sub-in-a-box as a home cinema sub?
I have a 10in Kenwood Sub still in the MDF cube I built for my old car, and wonder if I got hold of a crossover if I could use it as a home cinema speaker. I would also like it to use the feed for the front pair of speakers.
Presumably I would need to use a transformer power supply (no problem, I have a couple lying around)
Any ideas?
Cheers
Rob

Depending on the size of your car amp, you'd need a bloody massive psu (I have a 23A continuous 13.2v PSU and it cost about £100)... I think you might need a bigger one than that to power a big amp
Either that or just use a car battery lol
Just be careful!

Hi ya Rob
What type wattage is the sub?
Cause you can build amps to do this and I'll say, hope you enjoy electronics.
I've built one for my DTS amp at home and it too me a couple of days, I made a 100W RMS amp to run a car sub. Nothing is impossible

blackgti - I cannot remember what the sub is rated at, but it's prolly a 500W unit.
However, I have today bought an Active Sub and spkr kit from a local shop, so this week I shall be mostly wiring phono and SCART sockets methinks....
Thanks, for your comment though, I would still like to know how u did it...
Cheers

check impedance levals and make sure that the enclosure is solidly placed on the floor so that you dont loose bass through any vibration

Funny thing, i was looking to do it the other way around - thrash the hell out of my little HC sub by sticking it in the car (probably wedge it in the footwell or squash really hard behind centre console, maybe off to one side in the boot but maybe not loud enough there). Any stories to that effect?
(( it takes 12v from a transformer, and i have an old phone car charger i can dissect... ))

Most car subs are 4 ohm or below jobbies.Most home stereo ones are 8 ohm.There is a reason for this,related to the power supply.So,no.Most car subs will blow any amp connected to them,as the impedance is too low.(Home stereo,that is)
If anybody's interested,I can go into detail,but it's a bit geeky.
