Hi all! As the title suggests I'm doing this instructible on ammo box speakers! I came across this instructible > http://www.instructables.com/id/Ammo-Box-Speakers-1/ a good few months ago now, and this gave me all the ideas/concepts/designs to give me courage to build my own. I suggest you check out that instructible first just in case i miss anything out (the comments were especially helpful!) :)
I thought I'd tell you a little bit about myself as this is my first instructible.
Name :- William Roberts
Age :- 18
Bio:- I am a student currently studying Design and technology: graphics products, physics, maths and geology. I absolutely love DIY ideas and i am very appreciative of design influences. I love the great outdoors and i regularly participate in sports. I also love the occasional extreme sport (mountain boarding most notably). Live in the UK, you could probably guess that since i quote everything in £.
well now that introduction is out of the way i'll get on to the 'ible!
Step 1: Parts and Tools
On this build i wanted to keep the costs as low as possible but without sacrificing quality. To get it as cheap as possible this meant shopping around on the internet (Ebay especially!). Due to keeping costs down i did buy some stuff from China so this greatly increased waiting time in order to build. so, on with the parts list!
