Hey guys my current system is one 12" Q with a 1200 watt Hifonics and am looking to upgrade. I'm looking for sq but with some more dbs. I'm thinking of either two 15" Q's or two 15" Alpine SWR. My question is which one of these two would push out the most dbs but sound the best?

 

I would go with the Q, however dbs and sound best is not only driver related, the enclosure plays a huge part.

 

I was leaning towards the Q's as well but it could be bias due to me already owning one. The issue of boxes it would be nice to hear from someone who really knows about them bc I have no idea. I want both an enclosed and ported.

 

DEPENDS on a lot of factors including enclosure, power ect

 

Exactly !


OP, with regards to boxes I can help you with that.

 

Well with the enclosures I drive a 1994 civic so not much space. Yet, I'm looking for an all around good sound, so I guess an box that can give me good top and low range. Since I'm getting two 15's being loud shouldn't be a problem. I will most likely be powering them with AQ 2200 or 3500 or Hifonics BRZ2400.1D. i would go 3500 AQ bc I would get fully loaded Q's which i believe adds wattage to the already existing 1500 watts.

 

If you give me the max dimension Height, depth and width you have to work with I can figure out your box size and let you know how and if it will fit, also dont forget you will need electrical upgrades if you dont have any.

Some amps to consider depending on your budget:
Sundown Audio SAZ-3500D
Crescendo Audio BC3500D

 

My trunk is approximately 45 inches wide, 20 inches high and depth is 31 inches. I would like both ported and an enclosed box. Those amps are a little out of my price range. My range would be like $250-500.

 

also can consider these..

Crescendo Audio BC2000D $ 380

or AQ2200D Amplifier $ 430

Working on your sub/box recommendation, will update as soon as can...

 

Yea I was looking at AQ2200D but I really want to power these subs and fear that the AQ2200D wouldn't fulfill the Q's full potential. So, I may spring for the CRESCENDO AUDIO BC3500D, yet am worried about over powering them.
