Help!!! Scion TC FI Q 18

[Why So Cereal?]

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?

[Why So Cereal?]

Someone built it.for me. and yes music. Couldn't make it on her own- ice cube

[ge_off_me]

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

[Why So Cereal?]

it was metered on the dash...with a audiobox....or soundbox? something like that. nothing fancy just a little guide

[Bumpin' Goalie]

138.9 @ what?

Yes, you could try ported.

[BlactimusCrime]

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

[Why So Cereal?]

i dont know what frequency because it was off music.
Blactimus: i was thinking that too. but i still want to get as high as I can. so any more suggestions...besides ports (which im pretty much set on)

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.

[Why So Cereal?]

see thats the thing...its also my daily driver and i want to use it for music too...but also want to be able to do pretty good in small competitions too...or is my current setup already good enough for that?

[Bumpin' Goalie]

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

GTFO
tuning high is for fegs.
id rather have a groundpounder doing 142@ 35 than a fart box doing 150@55

[Why So Cereal?]

daily music and the occasion comp

[Why So Cereal?]

yea i agree...i def dont want to tune that high!

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