    I see a lot of questions on how to make your own ecaller popping up as usual during this time before most people start hunting snows for the spring. Who wouldn't like to have a crisp sounding, portable, last all day ecaller that doesn't break the bank. I certainly do, in fact I like having 3-4 of them. So here is my part list on how to NOT spend an ridiculous amount ($300-$500) on a commercially made ecaller and virtually make 2-3 for the exact same price. (Note; may be able to find parts cheaper elsewhere)

    The housing- 12.99
    http://www.academy.com/webapp/wcs/s...10151_10051_12502_-1?ICID=CRT:0145-00028-0140

    The amp- $18.90
    http://www.amazon.com/Pyle-PLMPA35-Channel-Amplifier-3-5mm/dp/B004HJ931M

    The Speakers- (2 to 4 depending on your preference)- $45.80-$91.80
    http://www.amazon.com/Pyle-PHSP4-6-...TF8&qid=1423002206&sr=1-1&keywords=power+horn


    MP3 Cable to Amp- $2.53
    http://www.amazon.com/Cables-Unlimi...ie=UTF8&qid=1361389178&sr=1-3&keywords=3.5+mm

    12 Volt Rechargeable Battery-(1 or 2 will run ecaller all day) $17.99 (Note: I use a piece of wood to seperate this battery from the amp so that it sits tightly and doesn't have to be removed for charging. )
    http://www.amazon.com/Volt-Recharge...sr=8-10&keywords=12+volt+battery+rechargeable

    Now your going to need 1 duplex 120v outlet, with faceplate. On these you need to break the copper connection that sits in between the screws so that your channels from the amp are separated. NOT doing this will lead to overheating of amp. These will have to be inserted into the casing but using a saws all to make a hole big enough for the outlet to set with the faceplate covering it. One channel of the amp goes to one part of the outlet, and the other channel goes to the remaining.

    You will need 1-2 Male 120v plugs. I say 1-2 because you can connect 2 speakers to 1 plug, just pre-twist the wire together before you put it inside said plug. If you want to have each speaker have an individual plug you will need outlet extensions. I recommend NOT doing this.

    Misc Wires for connects, and its always a good idea to have an extra fuse for amp.

    If needed I can provide pictures of completed product, but with a little intuition you will bang out an ecaller in virtually no time.

    Total Cost with 1 batteries, 4 speakers and misc parts(roughly)- $157 + shipping of parts.

    Adding a remote is at your discretion, I personally haven't found the need for them, but adding one is simple and easy and will add anywhere from $10-$25 per unit.

    Good luck, and remember "Save the tundra"

    Right on. Little bit different than this setup but same idea obviously. I will mention that this setup is basically a carbon copy(minus the stickers/component cover/remote) of one of a certain "manufactured" ecaller. I find it extremely ridiculous that someone would pay $471-$550 for something they can make themselves for the price I have listed. Will not say the name of the unit, but I think people can figure it out pretty quickly.

    That Lepai amp is a nice choice because it's a T class amp, which means that it uses very little power to produce a good range of sound. The problem is, the Lepai is a smallish amp for power. Remember that when you're reading those RMS #'s they are expressed for 4 ohm systems. The power horns we run are 8 ohm, which means that the power is diminished by an amount between 30 and 50%. The problem with this, is that the more towards the upper end of an amps power range you get, the more distortion becomes an ugly issue.

    I've made a couple recently with several different amps. The best of which is this http://www.parts-express.com/2x100w-at-4-ohm-tk2050-class-t-audio-amplifier-board-only--320-334. It's around $40, and the fact that it isn't cased will scare some people, but I attache the amp to the underside of the lid, upside down, so it will never get moisture and then I make sure the battery is well secured so nothing bangs into the amp.

    I've used the Pyle 60w horns although my preference is for the Nippon TC-55 for sound quality. I'll just have to see how well it holds up.

    This is very, very, very similar to the Squawk Box. Nice work way to help others out and save money. Very easy to make. Thanks juviesoup

    Can you put some pictures up?

    I laughed when I took apart a sqawk box. Was the same guts as in 2 of my e-callers that I spent $90 to build. I'm in the wrong business!

    Will do today.

    Some people must assume or think it'll be too hard/expensive to make their own? Obviously it really is extremely simple.

    you know you could ditch the CD player and amplifier and get a motorcycle SD Card player with a built-in amp...wire from the player to the box with plugins and male adapter to the power horns......and you will have the same thing! smaller more light weight and cheaper....I would use a sealed lead acid battery...saves on weight and size too!
