Amp cooling
Hey guys since im asking a lot of questions here, i got one more...... This regards the best place for trunk mounting an amp. Currently i have mine mounted on the rear of my box so when ur looking back from the front seats the amp sorta fills the access hole behind the fold down arm rest. I figured it would get alot more air there instead of in the trunk somewhere. I only had my volume up maybe 1/4 of the way and in about 10min. my amp was so hot i could not leave my hand on it for more than a few seconds... This is while im driving with the window down. It is bridged and running a 2ohm load, so it's about maxed out.....
Anyway just wanted to get some opinions about where it was placed... Anyone else have there amps mounted similar? Amp is a RF punch 400s, only feeding two alpine 10's about 200rms a piece is what is on them.

IT IS going to get warm/hot no matter what. You're running alot of power from it AND your running it at 2 ohms so regardless of what you do it will run hot. RF's have a tendency to run VERY hot, don't worry about it till it shuts off on you at which point I would suggest a higher output amp. How do you have the amp wired? Is it a 2 channel bridged to 2 ohms? If so thats not how that amp should be config'd.

Is the amp going into protect mode ? Ie.. Not subs playing. I would DOUBLE CHECK the wiring on your subs and verify that you are using the correct ohm load for that amplifier. Arnt the 400s full power @ 2 ohms bridged ?

Yes, my spec sheet says it tested 424 all channels into 2 ohms... I have not experienced the amp shutting off and as long as the windows are down with air circulating it does'nt get that hot.... I know if it was wired wrong the amp should shut off right? I have 4 ohm subs and the amp is safe down to 2 ohms..
Amps bridged and subs are wired parallel, so i know that's a 2 ohm load... No problems from the amp it works perfect even when it's cranked really loud... Must not be getting too hot, but i don't know that much about amps :
How hot do typical high watt amps get? I had a $100 jensen cheapo once, drove 1 10" sub with it and it would get so hot i think u could cook an egg on the heatsink! lol

I was looking on the RF website and it said that there amps do run hot because of the mesha technology. Transfers lots of heat to the heatsink more effecient than most. So maybe thats it..... If any of u guys have a RF amp there website is great for tech questions.

RF amps are notorious on getting warm, but double check your gain settings. I had my old RF amp mounted in a similar orientation when it was powering my Brahma 12, and it got pretty warm, but it never gave out on me.

Nah no fan or anything, today i was driving it pretty hard just to see how warm it would get, this is with the windows down with air blowing in.......... it was really warm but never shut down so i guess it's fine... I've had it since 02 and only used it maybe 10 times, so it's still new... Got it switch mounted so i only power it up when i want.........
Still it's maxed out into 2 ohms so what can i say? Never shut down on me so no complaints....

Now that I have more time to respond here's what it should be
if you have 2 4ohm subs you need to wire it like this
sub1 + to sub2 -
then the leftover outputs should go to the amps bridged + and -.
if you have 2 2ohm subs it should be wired the same way
if you have 2 8ohm subs you can wire both +'s directly to the amp's bridged + and both negatives directly to the amp's briged -.
if you have 2 4ohm subs you need to wire it like this
sub1 + to sub2 -

So, make sure your alternator is able to provide everything your throwing at it!... I tried many location for the amp, fans, and tons of other things, still got hot. Incase your curious my amp(s) (had two orions) never blew, but turned off alot
Good luck!
