Adding a fan to my amp.

[digitalrainman 10+ year member]

I have a cadence 6004 that has shut off about 3 times now, and from feeling it, due to heat. I have the subs hooked up correctly and the load is 100wx2@4ohms front to pg rsds, and 400wx1@4ohms bridged to a kicker cvr 12. It seems to run at 24 volume fine all day, but at 26 it kicks off after a few songs. I have my gains set at 35.

Anyways i have alot of 12v computer fans (80mm), and want to know how to hook them up to my battery and to only run when power is on to the amp. I have seen one that a company makes that is just for amps and the hookups are positive from remote lead, and ground to chassis. So does the remote lead provide consant 12v power? i thought it just sent some for the on signal then the off.

If it does provide power would that be fine to do, to just hook up a couple fans to the remote along with the amp, then ground it all to the common point on the chassis where i grounded my amp.

If i want to use two fans should i do it in series or parallel with the remote lead.

two fans should be fine on the remote wire. any more than that and you'll probaly need a relay. Just ground to where you grounded your amp. wire them in parallel.

Are you tapping into the remote wire or using it directly? if you just use it directly it'll be grounded through your amp

I would recommend getting a relay, mainly because you already have 2 amps hooked up to the remote wire. before i put in a relay in my car my head unit starting having problems when I had two amps and a crossover hooked up through the remote wire.

A relay is very easy to install, and would work fine to power the fans.

Yeah, I agree with this. Anything more than using the 2 amps on the remote turn-on lead could possilby and probably will damage the HU. Just get a cheap 30amp relay at autozone, its like $3, and only takes a couple minutes to wire it up.
