I HAVE A B.M.W 4''6INCH SPEAKERS IN THE FRONT AND BACK..
MY QUESTION IS WHAT IF I WANT 10''INCH SUBWOLFERS IN MY TRUNK IS IT COMPATABLE OR DO I HAVE TO HAVE JUST THE CORRECT SPEAKER SIZE FOR MY CAR..CAUSE I NEVER REALLY KNEW FOR SURE..
Don't really understand the question but don't worry about what you can and can't stuff in the trunk.
If you're gonna get woofers, you don't have to worry about it cuz they come with their own box.
Well you can buy them individually but you'll still need the box or boxes.
Go to an audio car shop over any commercial store.
They have more variety and will customize the box(s) to fit your trunk.
I would go with 12" woofers over 10" any day.
You're going to need an amp too so make sure you have dual rca jacks on your deck to control both your inside speakers and subs independantly.
I would recommend gettin Kicker "solo baric" it's what I have.
All I got is a 500 watt amp and it rocks the shit out my speakers.
But you can go all out and get yourself a 1000 watt amp.
Get professional sound equipment!
I can't stress that enough.
I blew out 8 sorry ass speakers one time.
Bose and infinity, which were mids and tweets.
So I got me a hold of some Soundstream component speakers and they've lasted me over 3 years.
