im gonna splice a 3.6v fan to the ground and the remote, but dont know how many volts the remote is. I dont want to burn out my fan

 

You don't want to hook fan to remote wire, as it can be deadly for your headunit. If you still want this, use high-impedance 12V relay and hook the fan in series with appropriate resistor.
I don't think it will solve your problem though. Where amp is mounted? Are gains set correctly with multimeter/oscilloscope? Too low impedance of load?

 

my amp is in my trunk. i cant fold down my back seat, so there's no circulation of air getting to my amp. all my wiring and levels are correct as to how the manual tells me how to set it.

 

somethings wrong with the amp then.....is the amp shutting down when it gets too hot? i guess my question to you is....how do you know the amp is too hot?......does it shut down? amps are suposed to get somewhat hot......but if the amp is actually shutting down...then something is wrong....if your amp is in the back...and there is plenty of air flowing around it, that should be sufficient.......nothing a fan is going to help with.......check the wiring....make sure your power wire is big enough.......make sure your not dropping your ohms below the recommended amps abillity to drive the speakers.....that would heat an amp up very quickly.......and these couple of things i mentioned a fan would NOT eleviate. keep us updated

 

A power wire that is too small will not cause an amp to get hot. The wire itself will get hot if too much current flows thru it but it will not cause the amp to over heat.

If the speaker impedance is too low that will deffinitely cause the amp to heat up. Any quality amp will go into thermal protection mode if that were the case. If the amp gets hot but doesn't shut down I wouldn't worry about it. MTX and Rockford amps are both known to get quite hot to the touch under normal conditions.

 

it goes into its thermal protect mode, then comes back on a few minutes after. it hasnt done this for the past two months or so. just recently. then again, i live in the phoenix area of arizona, and its starting to get hot, quick again. i am running a 4g power and ground to the amp, wired the subs in a series/parallel putting out 4ohms, bridging it to my 2channel, which is 4ohm stable. no paint interferring with the ground. i cant pull down my backseat, so there is no fresh air circulating in my trunk. im wondering if thats why its overheating.

 

well it has nothing to do w/ the ground....if it wasnt grounded properly it wouldnt work anyway......im @ a loss.....anyone?

 

im pretty sure its just suffocating being that its in my trunk and i cant fold down the back seat. am i right?

 

if your gonna do a big fan coudlnt you just hook a wire up to the posotive terminal on the amp??? then it would be bringing the power straight from the battery wouldnt it??? just an idea

 

dont want to hook it up to the positive, cause then my fan would be running constantly

 

The best way to add a fan is by using a relay. You cannot use the remote turn on lead for a fan. The remote lead is a voltage source not a current source. There is very little current available for running something like a fan. On top of that if you use the remote lead for the fan the fan's motor will emit noise that can easily be heard thru your speakers.

I wouldn't bother with a 3.6V fan either. You can pick up a 12V computer power supply fan for cheap almost anywhere.
