I have a speaker set, that says it needs 13.5V to run (13.5V DC IN, and
the big power brick thing says 13.5) - but my power brick is dead. I
just hooked up a 12V power source, and the LED came on. So at least I
know it's not my sub woofer (where all the speakers / volume control
plugs in).

Question is: can I run at 12v, just not as loud? Or will this blow
something up, cause a fire, etc...? Or will it just cause damage over
time? Or will it work FINE, with no major hazards, just not get as
loud?

Other numbers to consider:

ORIGINAL HARDWA
Input 120 VAC 60Hz 50W
Output 13.5VDC 2.5A

POSSIBLE REPLACEMENT
Input 120V AC 60Hz 23W
Output 12VDC 1000mA

If it works, just not as loud, I'm set... I really don't want to spend
more money on another powersupply.

Thanks!
