powering active crossover

bonsai171 · 4th November 2005, 01:49 AM

hi, a friend recently gave me two 15" Rockford Fosgate subwoofers in a box, and i have an electronic crossover sitting around that i would like to cross these speakers over. Is there an easy way to power it up for use in home audio? It would obviously need some kind of 110 volt to 12 volt power supply (any suggestions for that one?) as well.. Help!
Thanks.

Almost any regulated universal ac-dc adapter should do. 12-15V output(not so finicky as it is already designed to work in car) and something like 0.2A to 1A. Even your local supermarket might have these.
Something lookalike thishttp://www.ccrane.com/more-categorie...c-adapter.aspx

how would you hook up the remote turn on lead? That would need to be powered for the crossover to function correctly, right? Thanks..

just wire the 12V supply to the remote turn on. when the supply turns on the crossover turns on.
