Im a novice when it comes to car audio, but I am trying to learn. So now I want to know what it means to either go passive or active? I see it relating mostly to the front stage set up's using comps and tweeters. But im not sure what it means, and what the differences are. I am upgrading my system to what im hoping is a decent SQ set up, and I wanted to know the differences between passive and active (my HU can go active) so that I can talk to my audio installer about it, to see which he was going to do. My set up is
Active means your speakers are being driven at specific frequency ramges by electronic means. For instance. You have 6 channels of amplification and 6 speakers total. 2 channels bridged at 20-120hz drive your subs. 2 channels stereo at 120-1500hz drive your mid bass speakers. 2 channels stereo at 1500-7khz drives your tweets. All this frequency adjustment is done either on your deck, or through your amps crossover network, with no passive crossovers installed.
Passive is the opposite. The frequencies are set wider and you fine tune the front stage with passive crossovers.
These are all hypothetical numbers but should give you a clear idea of how it works.
