Are these new amplifiers really water tight? Doug, I don't know about those particular amps, but it's good practice to have two, *small* vent holes, in the bottom of the cases to allow ventilation to prevent build up of condensation. One hole does not provide for cross-ventilation, thus the two holes. 73, Charlie, N0TT _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK |
