Hi all...Firstly I would like to apologise for the extremely n00bish question I'm about to post...But I'm planning to upgrade my car's sound system and I need some info on amps. (actually I don't have a clue about ICE!:shocked: ) What's the difference between 2channel and 4channel amps? Monoblock? Magnet? I heard that you need one amp to power to mid-speakers and another one to power up the sub-woofer. But which one is for which? How many watts is sufficient to power the mids and sub? Which is better to get a woofer or a sub-woofer? Is there a difference between the two? Heh,actually I have a load of questions to ask but I guess this will do for now... Thanks in advance!
