House. if i can get CAR audio for cheaper then HOME audio, that means for the same price i will be getting more watts with a car system, then why not?

for your price range a home audio powered subwoofer is the easiest and simplest solution.

to run a 400watt car amp in a house, you would also need a 400watt+ power supply to get 12v to the amp, you would need a box for the sub as well.

so you could get an amp, a sub, a box, and a power supply, then have to hook it all up, or just buy a powered subwoofer and plug it in.

powered subs will use either an rca input, or you can run your left and right speaker leads into it.

you will need two full range speakers for left and right audio, in addition to the subwoofer

But now we're talking a lot of cash right? i saw some home subs on PE for $600+....

i would assume that with a sub, i could run my current L/R speakers, but i don't know how i could get the sub to connect. mine is plugged into the head unit using a cable with a circle head and prongs in it on each end.

not sure this is going to work out...home audio looked to be a lot more then the car audio on PE.

you can get cheap home powered subs, keep looking.

you would use your current left/right speaks

the circle thing with a prong is most probably an rca cable, the standard hook up

if its not an rca cable, you can just run your left/right speaker leads into the sub(called high level, or line level input)

you need to figure out if your prong thing is indeed an rca cable, if not you need a sub with high level inputs

a powered 10 will shake your house, a 12 will rattle stuff off walls. my sony 12 was 250wrms and was $200

edit: heres a powered 10 with 100wrms(225w peak) for $100 http://cgi.ebay.com/JBL-Balboa-10-10...3A1%7C294%3A50

So that sub will plug right in and shake the house?

for only $100 that's not bad....
