A crazy idea. Anyone tried?
I just had a crazy idea about how to power my power hungry 4ohm speakers. Instead of spending tons of dollar for an average amp that actually design to power 4ohm speakers due to rarety in US, I thought maybe I can just hook up an amp for cars to power my speakers. Since all the amps for cars are all rated at 4ohm there are plenty of supplies. The quality are suppose to be top notch as well with enough juicy for any good amp pushing 150w RMS x2 in any $150.00 and up amps.
Am I crazy?
or is this already been done?
Hows the result?
"We're gonna need a bigger boat..."
You're gonna need one heckuva power supply for them. Do you have any idea of the amps they draw when spittin' out dem watts? Here's a hint... a LOT!
A car battery can supply virtually unlimited current for limited periods of time. The more the current draw, the less time it's available. That's why those gigunda caps are there.. to store current.
The current a a home power supply can provide is basically limited by the house wiring and the transformers in the PS. ...and transformers are very expensive.
And, remember, a lot of the power ratings for car amps use, let's just say, "lenient" ratings methods.
It might be in your best interests to simply save up and get a home amp that's up to the job.
Oh, you might get by with a wimpy PS, but don't think that amp is puttin' out anywhere the wattage you think it is.
