HD3's are cheaper than any of your options from DD. Audioque is the sister company of DD so your getting same build quality.
Congradulations on thinking the louder the car the larger your penis will grow. If your trying to get up to 140's and like 150's you might as well get "competition" grade woofers.

(2) AQ HD312's

or

(1) DD 9515

and

(1) DD Z1

Upgraded alternator and battery.

You would still have well enough for your front stage and box.

9512 and a Z1....

I'd do the type R's. Your paying for way more than you need with the DD's. Your trying to hit 140s' on music in a daily driver, type R's will do that just fine for a bit cheaper than the DD's.
