at the moment i have a Kicker 654i running 2 sets of Mb Quart 6.5" components in the front doors with a Vibe VP4 running at 1 ohm to give my 4 DBAudio subs 300RMS each. like you say tho you only do it if you can afford it. its also best to go in stages like gets the components first and run them from the head unit, then maybe get a 4 chan amp and use 2 for the components. you can always get a sub for the other 2 spare channels later. saves paying out all in one go
