here's the deal. i have a FI Q 18 in about 5 cubes sealed in my scion tc. running off of a Cadence Dakota 2400 maxx...1200 rms @ 1 ohm amp. Today we metered it and I got about 138.9 dbs...which isnt horrible but definitely isnt good. I want to get to around 150dbs. Someone suggest a bass enhancer and go ported. I am pretty sure the ports will help but I am not sure about the bass enhancer. Could it be my amp? The sub is fully loaded (all available options) so SOMEONE HELP ME GET THIS THING LOUDER!!!

did you build the box yourself or someone build it for you? and did you meter this on music?

How did you meter it? Term lab? Audiocontrol? Where did you meter it? Outlaw? The dash?

i highly doubt youre gonna break 145 with that sub and power, even ported.

 

150 is huge, nateberrier had a BL 18 on 2k in a hatch, did 143 with the car sealed at the dash

More power is not how you go about getting 11dB more. Drivers won't even yield that much displacement.

 

139 -what you got off about 1000W

142 2,000W

145 4,000W

148 8,000W

151 16,000W

 

You need to do w hat everyone else does - make a ported box tuned to 50Hz and forget using this for music.

If this is for daily music, and not mainly competition, I'd construct a ported enclosure and tune appropriately.

Agreed. Though I'd rather have a completely flat in-car response at even less, too. :D

build a box, tune to about 33 and youll be happy. if u use aero ports you can adjust tuning and raise it for comps

I was going with aero ports because i had aero ports on my cvrs before. but what about simply porting the box I already have?

if you do that the ports should prolly be external so you dont make the box any smaller. im not sure what the Q's like as far as space, but 5cubes should be in the range for it

ok one more question. i have the sub facing upward toward the glass...so should I face the ports in the same direction or towards the rear?

      Haven't been here in a bit, and figured I'd drop a few random shots of some of the latest subs we've been building/re-building here at the shop.
       
      Full pictorials with step-by-step build pics are at our forum, if you want to see them all. I'll just post finished pics in this post.
       
      Don't mean to spam the place up.... just know how we all love to see random subwoofer pron!
       
       
      If you have any questios, please ask. If not, enjoy the pics.
