How do I give my speakers more power?
I recently took apart an old boom box and salvaged 4 working speakers out of it. Then, I thought it would be fun to mount them in my workshop so I could plug in my ipod and listen to music while I work. I've tested them out and they all worked when I connected the leads to wires from an old pair of headphones. The only problem is there not very loud, so I would like to give them some more power but I'm not sure how to do that. Two of them say 8ohm 3w, on the back and the other 2 say 8ohm 5w, and then I have another random speaker that says 2w, 8ohm, 4w max. So, how much power can those speakers handle (in volts and amps) and how do I hook them up? Can I just connect them in series with a wall wart and my ipod or do I need to build some sort of amp?
