the new setup will see my amp(s) face down, under the rear shelf.
No heat dissipation through the heat sinks, hot amp, distortion, possible damage.[/b]Hate to start something here, but I thought the functionality of a heat sink is based on increasing surface area of the heat source (the amp) and lowering the heat spreading resistance. The primary effect on efficiency of a ventilated fin heat sink in a free convection environment (like a trunk with no forced air movement) being the size of the fins (increasing the surface area) then in decreasing levels of impact, the ambient temperature, thermal coefficients of the fin material and the cooling fluid (in this case air), perpendicular air flow across the fins, thermal bypass (heat flowing through the base to the metal package tray), following finally by fin orientation in a low flow (no fan) environment. As they say hot air rises and heat sinks. Given the fact the amps were designed to be used in a low flow environment, the amps being upside down have an insignificant impact on the efficiency compared to surface volume and the regeneration air volume around the amp (the 3 to 6" the manufacturer usually calls for in their install sheets). Sorry for the rant. For me it's a big surprise that i actually remember the thermodynamic classes from college.
