hi every1 i have no idea about amps i have 2 x 150 watt 10' subs (thats all i know about them) that i want to put in my room with a car amp. can i do this? do i only need a 12 volt power adaptor? thanks for all your help in advance thanks shady
a battery charger is a trickle charging device, at low current.
won't work.

The "car battery and charger" trick used in a lot of car audio shops is a really bad way of making a power supply. Finding or building a regulated supply with enough current will cost more than just buying a decent home amp.
OR.......you can get crazy and do this....
1)Take 8 car amps and connect them in series (power input, not sound output) 2)Purchase or make a bridge rectifier large enough to handle about 2000 watts and connect amp array to the + and -(adding a 1 farad cap after rectification is a good idea too) 3)Use a small 12v transformer to power the remote turn ons on all 8 amps 4)Get 2 15" quad-coil subs 5)Make your neighbors cry!!!!!!
I know this sounds completely far fetched but i have done it. You end up with ruffly 15v dc to each amp with as much current as your 120 line and rectifier can handle!!!!
the problem there is that home circuits usually handle at least 3 rooms of a house, or two apartments in a complex, and they are 20A circuits. Unless you have a dedicated circuit set up for a high current load, and preferably conditioned, you'll encounter problems. That was the case for a single Krell KSA-250 amplifier with a 4 Ohm stereo load at home.. had to set up a dedicated feed for the amplifier and related components.
