Here's an explanation of the speaker setups, in a nutshell
All headunits have RCA Pre-outs. These are the outputs which run to your speakers that make them PLAY SOUND! Most headunits have 4 RCA Pre-outs which means you can run four seperate speakers. However as for some of the more special headunits, i THINK they can come with more pre-outs (i THINK..).
As for speakers, you get all the different types -the tweeters, the woofers (most speakers are these), or the splits (which are speakers with two or more separate speakers - mostly the woofer/tweeter set-up). Most speakers are simple and come as one piece; BUT, for some types of splits, the tweeters can be mounted separately. This is still essentially "one speaker" because the high/low frequencies are split up into the different speakers (tweeter/woofer respectively) for better sound efficiency.
To wire up speakers in a car, most people use one line per speaker. The pre-outs are almost always used in 4-ohm mode, which is just normal and is NOT worth explaining
. Some headunits come with more options such as a 2-ohm mode. With 2-ohms, you can run "double the power", and therefore hook up two speakers to one line, but you have to "halve" the speaker ohmage, from 4-ohms to 8-ohms, so all the ohmage stuff matches up (the higher the ohms the lower the 'power' - ...it's complicated stuff..). It works well, especially for people like me who want a temporary fix to 6 speakers, a sub, and only one four-channel amp
SO. If you personally would like to play 6 speakers at once, and if you include the tweeters used in the dash as separate speakers, then yes it is possible to wire these up with a normal headunit (and it's recommended! I did it too - cheaper, and better sound - better than more speakers, because the high frequency sounds that come from speakers are more directional [and should be put higher - e.g dash, door cards]).
If however you want 6 SEPARATE sets of speakers, then you will need either a headunit with 6 pre-outs, or an amp. And naturally I would suggest the amp because you can plug more speakers into the amp and then it sounds awesome!
Hope this helps Water_Boy! Sorry if it's confusing..i've been reading about all this for ages as I'm really into car sound. My cuz and I are about to make a fiberglass mould for my sub just like Louis did! Yay for sound!
