tesing equipment indoors

[bimma85 5,000+ posts]

I was wondering how I would go about setting up some kind of portable setup I could use indoors. This would be so I could test used electonics prior to purchase(car subs, amps, speakers, decks, etc), not something I'm gonna be listening too. What stuff would I need. Any ideas would be appreciated.

a car battery...

So I just need a car battery and a charger then?

yep...

dont charge it while your using the battery though, the charger cant handle it

and make sure its a sealed battery, or you have a LOT of ventilation

ventilation is still a plus tho even with sealed

I ues a 75 amp power supply

I like that idea more, anyone else? How do I hook it up the PSU, just pick any lead? dont they give out different voltages like 3 9 and 12 or something?

No, a 12VDC power supply will have one set voltage //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

75 to 100A is plenty for most bench work, unless you're load testing subwoofer amplifiers at full volume...

Right on, So if I wanted to try out a whole system hu, subs, amps, speakers etc. would it still be enough? If everything checks out at moderate volumes, it should be fine at high volumes, correct?

Individually testing each component should be enough...75A to 100A should be fine.

Ok, i'm kinda confused... How am I going to get a signal to the amp w/o the hu. How am I going to get that signal amplfied w/o an amp etc.
