I have a 15in fi q that I love but i want more bass. Im running 1500 rms and i dont want to change my amp just my subs. Im looking at the sundown sa 12. I would be getting a pair and making another custom ported box.

Ya or Nay?

I think the two SA-12's would have more output.

Could you post the specs of the box for your Q and your planned box?

I think you would be better with 2 sa 12's also.

I dont remember the exact specs but 4 cubic inch box with a 4 inch aero port, tuned to about 33 hz. The new box i would have to plan out im still deciding if I want to upgrade or not and deciding if I got the money lol.

for the pair of 12"s

its a downgrade.

I wouldn't do that box, port is to small. But I think the 2 12"s would be better.

Well haha I did that box and it is to small but its what I had available unfortunatly. But I think ill get those sundowns and build a nicer vented box and maybe a better am down the line.

Thanks for your input! Keep it comin you might change my mind.

the 2 SA-12s should give you a nice gain in output over the single 15" Q in the right enclosure

*With the right enclosure* the two SA-12's should give you a better output.

A single 4" port for the 15" ? Looks small.

Re build your box for the SA12"s.

Definitely think 2 sa's would have more output

agree, the two would have more output if you have the proper enclosure

two sa-12's would give you more output and sound good at the same time if you build the box right.

The first question that should have been asked, was 'What enclosure is the Q in right now?'

Rebuilding is always cheaper then buying new equipment.

X2 and, what do you not like about it that makes you want to change.

My first preference would be the one I can have the optimal box for. If your Q isn't already in one then I would suggest getting it there first.
