- First a big fat thanx to:
- grl@drutx
- al@qiclab
- lauri.uusitalo@ntc
- for your much appreciated help, now on to more good stuff!
-
- Having determined that my 12V/2.5amp supply is totally
- unacceptable to power a 140W mono amp (which is a car stereo amp
- BTW) I decided to look into deep-cycle batteries (used by boats and
- RV's - they recharge all the way & last longer) and just recharge it
- when not in use. At my local NAPA dealer those go for $70 minimum,
- however, while browsing the battery rechargers I found one that puts
- out 12V/10amps for $29! Can I use this for a power supply instead
- of a battery?? I suppose it would suck down major wattage from my
- outlet, but other than that, would this work? There are two fuses
- on my amp, one 25amp and the other 3amp. I assume the 25 is far
- above what the amp needs to run normally, so the 10amps should be
- okay it seems (120watts max.) This all seems like it'd work to me,
- what am I missing?
- Thanx a zillion again, in advance...
- Mark
