I've seen a second hand car poweramp (2x200W) for 69$.
Can I use this amp for a subwoofer?
Do I need some extra electronics? filter?

it may be rated 200watts at 5% THD
u mite get only 100watts at 0.5% THD(like my amp which is 0.01% THD at half the Rms rating)
running a car amp in house = 240v/110V ---14v (or similar)convertor
= expensive
some ppl use batteries but they suck them dry before the charger can charge it fast enough.
computer power supplies do it,but in tiny amounts!
u could build a power supply for lots of money $ urself,switch mode supply.
if u live in US just buy a partsexpress plate amp -cheap
if u live outside US ur unlucky,like me.high shipping.

OR do u mean run as a sub amp in your car????
if so, run your sub off it. if high notes come out, likevoices,u know u need a filter,an active Low pass filter.
dont pay lots of money $$$ for a low pass filter.
probably crossover at 70hz is good or lower.:-D
u can either buy a kit,or a working filter.

You can do what you want, of course,
but do you think the power rating 2x200W is correct?
Not PMPO?

Yes, DC instead of AC. If you can get an AC-DC converter that is rated at as many amperes as the car amplifier is rated you can use the power fully. I did some looking into this a few years back and I think the power supply I needed for my 2x150rms (@ .05%THD, I did check first) was going to cost me something like $180. Unless they are a lot cheaper now...
