reedal Posted August 5, 2015 Report Share Posted August 5, 2015 Someone did an ammo can build on this forum. Do a search for it and that should help you out some. If not then you can at least PM him for some tips SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...

Broke_Audio_Addict Posted August 6, 2015 Report Share Posted August 6, 2015 Sideshow_kustom did the ammo can build. Looking for the thread right now I'll link it if I find it. Found it http://www.stevemeadedesigns.com/board/topic/196688-ammo-can-build/ That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

aculous Posted August 10, 2015 Report Share Posted August 10, 2015 I did one in a tackle box. Word to the wise don't put speakers facing each other, I didn't really think about spacing at all...I literally threw some drivers in a plastic enclosure and well it just ended up pissing me off so I have a ghetto rigged passive radiator now . Also good idea about keeping the drivers small. Brace the inside and deaden it if possible. I highly doubt that amp puts out 15w's, Lepai is a little more reputable (at least he tripath 2020+ chip) and I have used them before. They put out like 7w RMS and are rated at 20w RMS so theres that. (see the BigDwiz video on the lepai and kinter amps on youtube and on this forum I bet) http://www.parts-express.com/lepai-lp-2020a-tripath-class-t-hi-fi-audio-mini-amplifier-with-power-supply--310-300 This one comes with the ps. Also if you want to do 12v I would go with a headunit, get one for $50-70 and it does the amp duties and you can plug in a USB. You don't need anything fancy and it will put out more then 7watts RMS. Just a thought. (also this assumes you are going to be running on battery power, if not go with the lepai) http://www.parts-express.com/wfr0400215-4-cast-aluminum-frame-woofer-4-ohm--299-346 either two of these or http://www.droppinhzcaraudio.com/nvx-audio-n-series-nsp525-5-1-4-2-way-coaxial-car-speakers/ Link to comment Share on other sites More sharing options...

Still not bad and its cool that you can throw it all in your car and be good to go. Link to comment Share on other sites More sharing options...

Triticum Agricolam Posted August 18, 2015 Report Share Posted August 18, 2015 You might take a look at some of the TPA3116 amps on ebay. I've been playing with a couple and they are really awesome, especially for the price!
