![]() You will also want to leave enough room around the sides of the amp to connect wiring and make adjustments for boost, crossover, and other factors. ![]() Mounting an amplifier upside down is a no-no, because the cooling fins will be on the bottom and dissipated heat will radiate back up inside the amplifier unit where it can't escape. The fins should face the sides or top of the amp. (Power amps can get quite hot to the touch.) When you select a location, make sure the cooling fins have plenty of space around them to dissipate heat which will radiate upward. To make sure heat can rise out of the amp and escape, make sure ventilated slats are facing up or to the side – not down.Īmplifiers have slotted cooling fins on their surface to release internal heat that builds up. While mounting an amplifier in trunk or hatchback areas is usually a good idea, securing it in an upside-down position (as seen here) is not. Distancing the amp from the head unit, using rubber mounting grommets, and/or mounting it to something other than the chassis will help eliminate this kind of unwanted noise.
