I have been told that I need a pre-out if I want to upgrade later with an amp/sub etc further on.
So been looking for a new headunit with pre-outs.
How many do I need?
I plan on upgrading the component speakers (certainly the front door ones at least) and getting a 12" sub eventually for the boot. I have gotten myself a little confused regarding amp channels and headunit pre-outs.
Please could someone clarify this up a bit for me (in lamans terms..I am new to all this )
What a difference I have come across so it must mean something! Some have 2v all the way up to 5v.
Is one better than the other?
Do certain voltaes limit which amps/speakers you can use later on?
I have a budget of £150 max (I have been...told) and for that money - while not a lot to you ICE fanatics I am sure - there are a whole bunch of technical stats flying about, none of which I understand properly!!
