Hi guys, I'm just new to this forum and relatively new to car audio so I thought I'd post up a few questions I have regarding my audio setup.
I currently have in the mail 2 (x2) SR104DVC subs, one pair of MM 6 x 9's for the parcel shelf & a pair of soundstream xts 4" speakers for the front. I am also looking at buying a pair of tweeters to help filter out the highs from the mids.
Question one; how many watt amp will I need to power my 2 front and rear speakers if my total rms value adds up to 420?
Question two; how many watt monoblock should I be looking at to power my 2 10" subs if they equal 1400 rms in total?
Question three (possibly a silly one)would it be a good idea to upgrade my alternator and/or battery considering all the power that will be running through the car? The only reason I ask is because it's only a '92 corolla (1.6lt 4cyl) so it doesn't really have a heck of a lot of power to start with.
Anyway, any advice, tips, helpful hints would be much appreciated!
