motorized amp rack

Make sure you get the connectors for them also. This will make mounting them alot easier.

To get the amp rack to actuate, you have to use a heavy linear actuator. find one that can push at least 1.5 times the weight of your amp rack (with amps) Any lower and the rack will move while driving and can cause damage to the actuator and the rack itself. You'll also need a 2 second pulse generator, 10 relays and 2 soft button switches. Wired together properly it will work with no problems. We use this setup all the time for actuated setups.

well a new found buddy of mine is selling me a 12" stroke linear actuator hes got laying around for $25. you cant beat that with a stick!. Heres the link. http://www.hiwin.com/la/laf.html

10 relays?!?!?! thats a bit overkill dont you think. Im just gonna do this setup. http://www.surpluscenter.com/grafx/Wiring_BTN.jpg

sorry about that link. This one should work. http://www.surpluscenter.com/Wire/W5-1577-12.jpg

the push and forget is nice but i dont think its worth an extra 6 relays. lol. I dont think i have that many laying around at the moment anyways. 2 is good enough for me. I dont mind holding down the button. thanks for the suggestion though.

I'm like you killer sonata. It's not like I didn't have a hundred bucks for actuators but I can't resist a challenge especially when people say it can't be done.

I built my motorized amp rack, to drop my amp down from the rear shelf in the trunk, using a windshield wiper motor.

Why a wiper motor? Cause scrap yards and auto parts stores are flooded with them, it already works on 12 volts, has multiple speeds and worm drive. You ever try to stop a wiper in motion? She's got torque! The worm drive means it can stop at any position and hold it no matter the weight.

Lemme see if I can find some pix fer ya.

Here's the rack as it traveled about two inches:

This is when it's fully open. When it's halfway it changes angle as it continues to drop slowly. I also built the moulded fiberglass enclosure for my 12. 

The pictures aren't the best cause they've been optimised for the web.

I'll try to find my mechanical construction pix.

In the meantime, here's a link to my control circuit : https://www.the12volt.com/installbay/forum_posts.asp?tid=80714&PN=2

Very nice, hotwaterwizard, I like the simplicity.

Now, how can I implement that into my next project? Hmmm.....let me see

I'v found another cheap alternative to the expensive actuators from select products or auto loc. Use power seat actuators from the scrap yards, they come with all the wires and swithes you need. Plus they are capable of moving large amounts of weight. I try to get them out of old caddies or lincons because they are the strongest iv'e found to date.

Please don't miss understand me i think select products and auto loc are great companies I just feel that sometimes these companies are a little too expensive for certain things.
