overheating


hi i have an MA 6900 mcintosh amp only problem when driven hard for a long period will cut out on thermal overload any thoughts out there on cooling.
hopey
thanks, det.tech.speakers do it easy .lower volume great idea .but this is a party room and we may not be audiophile purists but we love music,i was thinking maybe some sought of cooling fan or more heat sinks or whatever, any thoughts?
First check to make sure that there are no restrictions to air flow to the amp. If not, then yes you can use fans, but if your Def techs are a current model w 92 db 8 ohm sensitivity and you are pushing a 200 wpc amp so hard it goes into thermal shutdown, you might want to consider going w a pro sound reinforcement system (and buying stock in hearing aid companies)!!!! Really, dude, Unless your "party room" is the size of an auditorium, that amp should be able to push those speakers to 110-120 dB levels which will toast your ears pretty quickly.
