Galactifan, Mardikrewe has quite the sound systems... here are the details I'm posting up for him.

Mardikrewe's sound system.
Installed components:
1. 1st generation Nano Ipod.
2. 4 Altec Lansing 360 sound speakers (On sale at my Walmart for 10.00).
3. Battery back up (11 hours, ......... tested good for more).
4. Wireless remote control (works when it want to?).
Yes, it does weigh a bit. Speakers are connected with spliters bought at Radio Shack for 3 dollars.
Might be considered by some ......... overkill?

Wireless remote ............. bought off Ebay ......... 7 dollars.
The speakers themselves are powered by their own (3) AAA batteries so the Ipod does not drain so fast. I have actually used the system for 6 straight hours and still going.
STUPID LOUD! I think everything ran just over $100 to do as everything was on sale or from Ebay.
Guaranteed to turn heads from the noise level and once they see you .............. well, for some reason they continue to stare. hehe.
Actual sound track purchased from ChrisD (forum member) and another guy from Ebay (eye warble only).
Total all together with tracks ........ right at $150 (not counting the 12 batteries .... I already had a lot of rechargables). Same price as Kropserkel but I am 4 times louder with 6 different tracks I can play.......did I say loud?
