No way, if he wants OUTPUT over punch he wants ported. Bandpass boxes are a JOKE for output and sound quality.

Personally I only run SEALED speakers...Currently I have a single 12inch sub on 1100 watts RMS in a 0.8 box and it gets LOUD..not super loud but I'm guessing mid-high 130s.

You stick a quarter on the middle of the trunk and usually it will get launched off the first "bump".

Bonnevilles do suck for output though compared to most other cars.

Sound deadening and a ported box will do wonders. I'd invest at least $80 or $100 at the minimum into some E-dead, thats the equivlant to $300 dynamat and its the same product.

edead is $1 a sq foot for 45mil which will give you 100 sq feet for $100, enough to do the trunk several layers thick.

Default sealed box

I just entered my first SPL comp over the weekend.

I have 2 Punch 12"* in a sealed box, and they bump well enough to get me 3rd.

Off topic, but a question...
I have some more work to do and tune my car. I am trying to find out, online, what the bonnie tuned freq. is when they designed and built the car.

I seem to hit best at 47 Htz..so I am assuming its around that.

Any ideas?

i agree that sealed boxes are the best bang for the buck.. i was running a rockford 801s amp with dual 12'* audiobahn and i got very good sound...

im out of the stereo world though, to much weight

on a 2002 termpro I could hit 136db with my single 12" sub on 1100rms. this was with a 1.0 cu box AFTER displacement (I had it inversly mounted) My pb of 136 was with that sealed box and at around 43-44hz

we put that same sub with the same amp in a 1.4CF (after displacment) box and tuned the box to 32hz and I was pushing 139db.

significantly louder in a ported application, every speaker is different but as a general rule of thumb a properly ported enclosure will own any sealed enclosure as far as output is concerned.

obviously if you look at these T/* params.....my sub clearly likes ported boxes better from the FS/BL and QTS numbers. It also clearly likes LOW freqency ports when using ported, a high frequency ported enclosure would probably be about as loud as sealed on a meter and sound much worse.

T / * Parameters
Qts : 0.41
Qes : 0.45
Qms : 4.71
Vas : 47.27
Sd : 0.0465 m^2
XMag : 29.5 mm
XSus : 26.0 mm
XMax : 26.0 mm
MMd : 216 g
Fs : 27.3 Hz
Bl : 17.49

Ported over sealed will net you around ~ 3dB from what i remember correctly. Bandpass are generally louder then ported, but only over a very limited frequency range (hence the bandpass designation). A good bandpass box will have decent freq distribution on it'* own, and then EQ'* will take care of the rest. There'* no real reason to use on though IMO.

Actually when you get into really high numbers you have to go back to sealed, because ports slow down the woofers, and cause too much distortion.

The bonneville is hard to get a lot of noise out of however. But driving around blasting bass just so someone else can hear it outside of your car is kinda silly IMO. If you want to be heard, get a 15 or two, put them in a ported box, and let'r rip. You have to be playing the right stuff too. Getting below 30hz is important... I'm not talking about specs either, i'm talking about real world play-ability.

A 4th order bandp[*** will be around 6db louder in the passband. It will be a very boomy box with limited frequency response, and almost always detrimental to sound quality. A properly designed ported sub will usually get you an extra 3db over sealed. At higher power, a ported sub will still be louder. The port acts as a second speaker as you get closer to the tuning frequency hence increasing output. If you drop below the tuning frequency at high power there is a very good chance that your sub will over excurt and probably get damaged.
