Modding help!!

my dad bought a midiland surround sound system from a yard sale. but it doesn't have the power adapter for the ditgital box.

the spec are
input:120v ac 60hz
output:12v dc 500mA

my question is can i solder a wire to the box and put a molex connector on it for the power instead of buying the power adapter?

 

never mind did it and it worked

 

Make sure its not pulling to much power from ur psu cuz that might hurt it.

 

usually the most draw comes from the sub (usually powerd on its own) but a few speakers shouldnt go near 300+ watts constant. the onyl question is will the draw be that much more than the output? Obviously it will draw a tiny bit more for the display and lights and stuff, but if its outputting 200 watts will it at that instant draw a little over 200 or will it be more/less ?

 

the sub has its own power i am just powering the box with the lcd and the controls

 

thats fine then, just make sure you have a stronger power suppy. then you are in the clear.

 

Stop worrying him already. If the box needs only 12v dc at 500mA, then even the most bog-standard PSU can manage. Just look at the Amp rating on the 12V line of your PSU. It must be at least 10A. 500mA is one-twentieth of that!
