amp rack build in progress

Cool, thanks for the suggestion. I'm hoping to install the rack this weekend and I'll see how loud they are. The fans I got supposedly run at 18-20 db but it didn't say if that's at full tilt or not. I'll look into the controller if it's an issue. Thanks again.

Yup //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
So I spend all day yesterday running the 1/0 power wire, speaker wires, remote turn-on, RCAs, Symbilinks, etc. in 95 degree heat. Hands getting chewed up to the bone routing them under the door seal trim panels and carpet. Blood, sweat and no tears...yet.

LAST FUGGIN thing to get through to the back: the RCAs. It was a tight fit through the part of the paneling I was routing through but I got a grip on the thick cable where the 4 RCAs meet. Start to pull and it's being stubborn. Pull a little harder and it starts to move. Then my sweaty azz hands slip off the cable and my fingers rip off the red RCA plug as I lose my grip.

So yeah, no tears but a "F**K THIS SH!T!" that echoed through the neighborhood and a search for my soldering iron began.

same thing happpened to me on that exact cables i was pissed as well although mine came apart in the dash so it wasnt as bad.

very clean rack, looks awesome!

Here's my 2 cents regarding the fans. I would personally do all fans mounted pulling the air out of the rack in one direction, and have holes large enough on the other end of the rack to not restrict the amount of air flow the fans are capable of moving. In a push/pull system, the total amount of air that is able to be moved out of the rack is still limited by the fans pulling the air out. In other words, if you had six fans, and you used three each in a push/pull configuration, total air movement is the capacity of three fans. If you used all six fans in one direction, that's almost double the air movement, minus perhaps a minimal increase in air resistance from each fan. Push/pull roughly halves your air moving capacity, or doubles the fan noise, depending on how you look at it...

I agree as long as your Airflow is over the heat syncs. For an ideal single "out" fan setup, you'd want a fan mounted on the top of the amp rack to blow the heat out and you could just use vents on the floor of the rack to vent cooler air in. If you have side mounted fans, I think a push pull helps tremendously bcause it helps move the heated air away from the amps towards the "out" fan.

Installed yet?

Any installed pics?

Very nice

I would do the fans like a computer case.. 1 in each corner, both pulling air from the same direction.. 1 pulls it in, the other pulls it out. Works very well.

agreed. you can also find variable speed controls for those fans. you can mount the knob in your center console so you can turn em up when the bass goes up.

or you can find temperature sensors that give em more volts to speed em up when it gets warm.look at newegg.com for fans. i bought a cpu fan that sounds like a blow dryer when its cranked up.

Stinger electronics makes a variable temp-activated switch. I'm using this on mine in combination with a 5v voltage regulator. At temperatures below the activation point, the fans run at 40% from the power regulator. Above the cutoff point, the fans go to 100%. The regulator and temp switch are running off turn-on-lead power. I built a makeshift heatsync for the voltage regulator because it gets really hot.

Here are some pics:

^^^ nice work. how much did that run?

you may save some green and get computer case fans though. sometimes CA accessories tend to be overpriced because they say its "specialized"

i used an spl meter from a computer in a center console using a 5v regulator. it was neat, but no real point to it other than lights and moving parts.
