Re: replacement for an Apex Senior subwoofer amplifier |

Not knowing the amp speaker combination, I will guess at the problem.
1.) could the amplifier, particularly the outputs and drivers be overloaded regularly? This would show as heatsink temps that are too high.
2.) could the output and driver devices be underspecified for the duties they perform. A comprehensive analysis of the temperature de-rated SOAR into a reactive load will tell whether this is the problem.
3.) is the amp properly specified for the load that the speaker presents. Many amps claim 4r0 stability but are incapable of supplying a reactive load of 4ohm. They are in effect 8ohm capable amplifiers. This possibility would be uncovered by using the same temperature de-rated SOAR analysis for resistive and reactive loadings.
Hope this helps.
