Car audio amps work well with home audio?

Well, i just scored a sweet deal on a monoblock amp, and was wondering if there is any reason i shouldnt use a car audio amp for a HT setup for my subs. I will be running 4 12's, and the amp will be a perfect match. Is there anything i should know?

If its a beefy amp your also going to need a beefy power inverter, which usually isn't worth the expense.

edit: how much power are you going to need?

Just get a plate amp if you only need 600watts. What subs you going to use and what size/type of enclosure?

Get 2 240w plate amps from PE for $99 apiece. It'd be a lot cheaper than getting a power supply and an amp.

Ive tried this before. Went out and bought a 50amp DC power supply (like $150), hooked up a couple 10" subs to a modest amplifier (like 200 watts), and I could barely turn the piece of crap up before the power supply would cut out.

Point is, getting a DC power supply large enough to supply that sort of current... is expensive. You are much better off just buying a 120v amplifier of some sort and using it.

Simple battery chargers are not a good idea, for more than one reason. Unless you get a pricey one, they do not monitor the battery for over charging. id hate to create a lead-acid bomb in my livingroom. Secondly, vented lead-acid batts give off poisonous fumes when being used. Not a huge concern in a house, but just another reason to avoid the whole 12v amplifier in your house setup. Its not simple, its not cheap, and it can get messy.
