Hey guys,
So new to this site, but I've had the F-150 for a while and I'm finally ready to upgrade the sound a little.
I want to get the Atrend Dual 10" enclosure
Two Polk Audio DB1040DVC Dual 4 ohm 10" db Series Subwoofers
And then on the amp I'm a little lost I don't know brands or anything really and the dual voice coils has me a little confused as to what power rating I need. Any suggestions? Also if you have a better speaker in mind that's in the same price class let me know as well.
Thanks!

 

POLK shows these as 'marine certified'.
Are these meant for boating?
Have you checked into the Atrend boxes, their volume, and compared with the recommneded volume for these subs?
These boxes are inexpensive. They may be only held together with screws & some glue.
Maybe build your own?
Plenty of box calculators out there with designs, and "how to's".

The box is going under the rear seats, correct?
Have you checked the depth of these subs... will they fit in the box?
Rockford Fosgate has some shallow subs, 2 and 4 ohm dual voice coils available.
That gives some flexibility with amp/subs and wiring.
My 2 cents, If you buy the POLKS, I'd go with an authorized dealer.

Good luck.
