db drag today
#26
I've been told my 2 10's are probably in the 145 to mid 150 range, but no official numbers yet. Maybe later on this year I'll take it through the lanes
And in most spl drag events I know of they either force you to wear ear protection or force you to stay outside the vehicle while it's cranked up.

the subs can probably do the number in the right application... but can the 8? take ur back seats out totally and fire the subs into the car, with the correctly tuned vented enclosure, batt and amp power u will maybe get a 150. i personally would'nt use a 8 4 spl applications this extreme.

they're 8's made by elemental design. he ended up blowing a bunch of those subs. he took it all out now and is working on another setup, but i havn't seen it yet.
You'd be surprised how hard it is to increase db up that high. to put it into perspective, there was a truck there with 15 15's pushing 162.

At that level it is difficult. the focus is so neatly done, nice! reminds me of my 1987 nissan with a wall housing 4 12'' pioneer tsw306c 1000w woofers running 2 powerbase d5000 amps in tandem @ 18v but in a vented enclosure pushing a 154,5 official best. why doesnt ur friend do away with 4 subs and go vented? he'll climb 2 - 3 db's at least... is he running std voltage or higher battery set up looks more than sufficient? ur car steakyboy, r u firing the subs into the cab or back?

I have a single 15 firing straight up. Look at the first post, I think there's a pic of it
-Steakboy
EDIT: Ooops, it's not, so here it is:
The box is the spec size for soundstream. the amp gets plenty of power and doesn't even get hot. The only reason why I get lowish numbers is simply the amount of air getting into the cabin. I'm going through a very small opening because of the box size.

The amp is a soundstream PCA1500D. max power is 1500Watts. the battery cable is 2 GA I think. it is a monoblock amp. The sub is a Soundstream Tarantula T4-15. 1000 watts RMS, 2500 Burst. The box itself is 4.25 cu/ft with 3" X 3" Ports. I like to drive with the passthrough out usually, and it's definately out when doing a comp. I'm pulling off the stock battery with no or very little dimming.

dude the setup is nice...but if you want to win spl you should take out the back seat make a baffle board across where the seats were. and put three of them subs facing directly into the cabin. if you want to win spl....or unless your trying to win a specific class of spl. 136 for 1 15inch sub isnt bad. but if you want to make heart skip beats its gonna take a bit more. and a setup in the trunk isnt gonna cut it.
plus do you even have capacitors?? upgraded altenator?? everything dynomated?? and i mean everything....firewall, doors, roof, ...did you strap down the trunk lid?? you may not think your drainig power just because your lights dont dim that much but you may be down around 10 volts...and if your amp is rated 1500@ 14.4 volts it may only be pushin 1000 if that.

Like I said before, I'm gunna be changing it up. I'm gunna leave the cabin of the car as stock as possible (no removal of seats).
As it is, the setup is nice for 2 reasons.
1) it looks amazing and is very eye catching.
2) it sounds very clean for every day use, and can get decently loud.
the setup sux for 2 reasons.
1) it wont win class comps.
2) i have no trunk.
All of your advise is great and appreciated. I will take all of it under consideration when I redesign my system with 2 reference 10's.

i think your using your sub effieciently for the volume your getting. but if you want to win spl??? i mean those guys build there cars around there speakers. the 8 s to nice for that. if you get those references compete for sound quality.

I agree. U either want spl or sq. this is my way of getting the best of both. The sub u got being dual 1 ohm is not the ideal configuration cos if it's a dual 1 ohm if u parallel it will basically b a dead short, which will keep ur amp going in to protection or even blow. so u series it being 2 ohm if u running a monoblock u using half it's power being a 1 ohm stable amp probably why ur lights do'nt dim much. If using a 2 or 4 ch amp, bridged the amp will also do as said cos the amp sees 1 ohm. The best advice to get bass into your 8 with out removing seats and still having a good looker is if u do change ur set up... get two 10''s or 12''s and build a enclosure as close to the sub as possible horizontally and vertically just make it pretty deep to get ur required volume. positioned behind the seats facing the back of the trunk with a sub on the far left and far right with a opening in the centre the size of the opening where the clip out panel is. doing this u'll b creating a loading effect in the trunk and the bass will build up and reflect through the opening and into the cab. now ur probably blocking a good portion of the opening. tried and tested, works great and the frequency coverage is good. keep me posted when u get ur new subs.
