Need expert answers about sound!!!!

Hey,
I work at a Toyota dealership as a sales consultant, and I recently bought a 2006 Tacoma Pre-Runner SR5 double cab(full 4 doors). I would like to add a few things to it, and I wanted some advice.

1) what's the best type of sub-woofers to put in there since there's not much room in the back, and how and where would I install them.

2) would it be possible to put 12" woofers or would I have to go with
10's?

3) about how much roughly would that cost with the box, amp, and 2
woofers?

4) about how much would it cost to tint the windows...say about
30-40% tint?

5) can I add a converter of some type to the stock radio and still hook
a amp to it and would you recommend this?

6) what's the best type of pipes to install for a nice rumble, not too loud,
but still enough to hear a good roar at around 3500 RPM?

7) where can I get some aftermarket sound that sounds good but is not
too expensive?

8) i saw some posts about how to "smoke" or "black out" the headlight lenses...would you agree that is a good idea to try to do that or no?


I think that's about all I have for now. I know it's alot, but if someone could help me, I would really appreciate it. I am GM and Chrysler certified as a technician, but I don't know too much about Toyotas.

A lot of DC owners have shallow mounts behind the rear seat. I'm sure someone will post a pic soon. I think usually 10" subs.








And somebody else will help with the other topics.

 

Answers above in bold.

 

BTW, I have pics of my install in my gallery.
