I have a sony xplod 1100 watt sub that I want to use in my house and the amp for it is a sony xplod 600 watt amp made for use in cars. Can I convert this amp for home use?

+1 it's unlikely a person in a home would ever run at more than 10W continuous power as that would blow your ears out. You could use a 12V supply good for maybe 10 - 15A and provide large capacitors near the power amp to supply transients and it should work fine.I can't say for that particular amp, but it's typical of most of these car amps to be rated in fake watts (some type of "peak music power" watts). The "600W amp" is likely a 12v 100W RMS amp at best. A 12v 10A or 15A PSU would probably be plenty. Anyway in home audio use an actual 20W RMS in music will be unpleasantly loud. Only silly teenagers at parties need more than that... Darn, am I sounding like AudioGuru?? Please shoot me now.
Thanks guys, all great input. One more question though, say I have a psu that would go well with this, where is the audio input jack? I'll upload a pic to help .https://imageshack.us/photo/my-images/26/003fmn.jpg/

Good point. I assumed true RMS music power or true RMS power not peak power or any of the ******** ways they advertise power. Also I have noticed said same in that 20 watts in an average room is more than I need.... unless the tunes are chasing several good beers.

very true.. No one needs 100 watts at home! I still use tda2030a amp with a bridged 2030a for subwoofer and it is plenty for me.. But i can't understand that how to get 1100 watts output using a 12V supply? I mean what kinds of Ic's or powertransistor do they use to get 1100W For a car amp? Or is the 1100w label one of those old business tricks?
those answers were helpful, so i think if i have 6 tda2030a chips, and each 1 of them produces (except one as it is bridged and used for sub exactly) 18W so 5X18W=90W And only 1 of them produce 35W(2 tda2030a's bridged) so 90W+35W=125Watts!, then can i say that my amp's total power output is 125W True RMS!?..
A 20W amp is FAR too small - it leaves you no headroom, and you're going to be hitting distortion on peaks. Modern speakers tend to sacrifice volume for higher quality (particularly with small speakers), so you tend to require quite large amps, so you have decent headroom.
CD with it's much larger dynamic range has made it even more so.
