thinking of uprading the car sound slowly, and was thinking of puting all the speakers threw an amp. It has 9 speakers should i be buying 2 4 channel amps or what ?. if i start puting stuff in parallel its not good ye ? also want to put a sub in to but not sure how many amps i should be putting in. in my previous car i just had an amp for 4 speakers and a mono amp for the sub pretty basic. Also i will need a line out convertor , does this mean i need to create a singnal for each input on the amp or do i only have to tap into one source.
Sorry if i made it sound abit confusing
and yes i will be upgrading the speakers
9 speakers why is there an uneven number? (not good with VE audio)
but why dont you just run your rears off the head unit and the front speakers off the amp and your sub(s) and run them off an amp? so therefore your only having two amps? and if your head unit has 2 rca ports you will be cheering.

OP -
If your not going for a multi media setup and planning on running 5.1 audio, then i advise to disconnect the centre speaker from the current setup. Not only is it a a poor quality speaker, but it will ruin your sound stage, particulary as you begin to upgrade further components.
So once the centre is disconnected, despite the over all speaker count, you still only have 4 speakers.
So you have a few options with regards to amplifiers and powering a subwoofer, i'll list the most basic which should pretty much cover what you have in mind.
Option 1 -
Using a 4 channel amp, you can either, run the front speakers from 2 channels, and bridge the remaining 2 channels to drive a subwoofer, and power the rear speakers of the factory head unit's in built amplifier.
Option 2-
Using a mono block amplifier to power a subwoofer, and continue to power your speakers with the factory head unit.
So it's up to you which way you would prefer to go about it. If you begin with a 4 ch amp, you can always add a mono block further down the track if you would like additional power, and seperate amplification for the subwoofer. Alternatively you may be happy with the outcome, or choose to do either in the reverse order.
Once you have a low level signal, you can split the signal to provide inputs for additional amplifiers.
