Its not getting mounted upside down... there aren't any wires run to it. Its either going on top of that fold down, or on the back of the seat... Still the seat isn't vented so I'll have to see how visible it is from the front on top of it

that amp will be fine upside down. i dunno where that whole rumour started from, but seriously it's not gonna matter that much.
the amp is cooled by a heatsink, which conducts heat via conduction, not convection, so it's not gonna make enough of a difference whether it's facing up or down, as long as the heatsinks have air passing over them it will cool the amp.
this info is coming from the guy who has run amps under seats, upside down, and sandwiched between wood and plexi for 6 yrs and never had one amp die on me, or even cut out because it overheated for that matter.

i will however comment on the size of those "enclosures" and how wavy/ugly they are. c'mon chase, i expected better

Scott, there are physics behind why mounting an amp up-side down is bad and NOT a rumour.. I have to run right now, but I'll give you the details when I get back. Several owners manuals state not to do so.

Alright, back now and I have time.

When an amp is mounted normally and in use the components on the amp generate heat. This heat rises away from the components and hits the top of the amp where it is dispersed through heatsinks and the amps chassis.

When the amp is mounted inverted, the heat from the components also rises, but instead of rising to the top of the amp where there are no components, the heat rises to the circuit board. The circuit board does not dissapate heat like the amp's chassis and the board heats up, in turn heating the components on the amp even more. If an amp is not being pushed very hard, it is not generating as much heat, so mounting upside down is ok in some cases. If an amp is being driven hard, it is very likely that it will overheat if mounted up-side down unless it has suficient cooling...

ok, first off, i have a physics degree
second, i need to clarify. i'm not saying that it won't make ANY difference. i'm saying that it won't make a SIGNIFICANT difference.
it's my opinion, that mounting an amp, in an otherwise well ventilated area upside down, that relies solely on heatsinks to dissipate heat, the amp will be fine. it will probably run a few degrees warmer, but still well within it's operating range.

if you are the type of person who plays music as loud as you can all the time and drive for hours on end in the summer. it MAY cause premature failure of the amp, but i've yet to see proof personally.

i will tell you this much, mounting an amp upside down in a well ventilated area is certainly not as bad as mounting an amp in a small sealed off space. and i've seen amps running strong for years in a small sealed of space.

here if you want to prove me wrong, do a little test. mount an amp normally and run it for 30mins, then measure the temperature(of the inside, not the heatsinks). give it a day to cool off or wait til it reaches ambient temps. then mount it upside down and run the same 30mins of songs through it at the same volume, and measure the temperature. then do a little research on the components inside, what temps can they handle on a continuous basis, intermittent basis, not at all. is there enough difference in temperatures inside the amp to conclude the components are wearing out much faster?

i think the problem with this myth is that ppl are using the old touch the amp method to see if it's hot. well guess what, if you touch the heatsink, and it's hot, that means the heatsink is working WELL. the problem is that not enough air is passing over the heatsink to adequately cool it down. so what i'm saying, is that all things being equal, a colder heatsink means WORSE cooling of the components inside.

well, getting WAY off topic so i'll just leave it at this.
amps are designed to be installed facing up, and placed in an area that has good ventilation. in these conditions the amps will have optimum cooling capabilities.
mounting an amp upside down will reduce it's effectiveness
mounting an amp in an area without good ventilation will also reduce it's effectiveness.

it is my personal opinion, that mounting an amp with poor ventilation is far more hazardous than mounting one upside down.
it is also my personal opinion that for 90% or more of the ppl who will use amps in there cars, mounting it upside down will not have a significant affect on the amp, it will still be well within it's limits

now chase, for the love of god post some progress and end this

no, this is fun. lol

I want to hear the debate, this is one of the few debates with either of you guys that I am not involved in. Its nice. Sort of like when you tried to convince me that autos are better then standards . But lets not get back into that!

fiero_silva APR 16, 02:28 PM
Scott, if you are so confident, let me use one of your amps for the test
fierce_gt APR 16, 04:29 PM
sure thing, if you can blow an amp in 30mins in a well ventilated area you are doing something SERIOUSLY wrong.

but in all honesty, if you want to do the test, i'll supply an amp
