Hi!
I have one of those famous (actually I dont know if they're famous around the world, but here they are :D) Logitech 5.1 soundsystems for my TV (http://www.logitech.com/assets/15653/15653.png). They have the electronics (including amplification) in the subwoofer, and a cinch connector to every speaker-module. Unfortunately, the wire is too short for the rear speakers, so I buyed an extension wire. The problem is, that the rear speakers are now too quiet. I thought about aplifying the signal again where the extension wire connects to the speaker-wire, but I have no idea where to look for a project like this. Could this be a headphone amplifier? Or what could I do? Probably for the main task no Arduino is needed, but I'm sure you can help me anyway
Thanks!
