Subwoofer Box for four lanzar 15"
what r u trying to do ?shake the car apart?Only kidding that a good questin 4 15: woofers in 1 enclosure>?what kind of enclosure ?how much space r we working with ? i use to be a installer , i also built costume boxes.I need to knoew how much space u have is it a car van,pick-up?I think an iso baric enclosure woukld be your best bet, it would take up the laest space. What frequency are you going to be runnig to your subs? what do you want? punchy bass,over the big tom drops?
what amp r you running or should i say amps?
you'll get the highest spl in a sealed enclosure,but i dont think thats what your looking for.you want heavy vibrating soud,am i correct? a band pass box will give that to you in a close space.bass sounds better and louder the further away you get../.give me more info then ill give you a layout.but 4 now this might help or solve your problem
they have all the wiring and p[hyschics and designs of boxes. rating please.
I have a fifteen inch lanzar max pro p145d and
I would go with a sealed because ur trunk is small and sealed would be the smaller box. I recommend 2.0-2.75 cubic ft sealed. for vented would be 3.25-3.50 after woofer displacement. Also I would recommend a reverse wedge meaning the woofer would go on the back side of the box not the angel side because u can slide the box in further saving u a little more room. I'm doing that same box now for the same sub but in a Nissan 2001 sentra. My box when done will be 2.78 cu.ft. After displacement. Sealed. 720 watt rms power acoustick 2ohm stable mono block to get longer life out of my sub.
I HAVE TWO 15
that mainly depends on the type of music you will be listening to. If you need clean, punchy bass, use a sealed box. For more growl, and louder bass, use a tube ported or slot ported box. I would not recommend a bandpass box for 15"s but they do make them. I have 2 kenwood 12"s in seperate slot ported boxes with a SPL 1500 watt amp, making about 149Db in a 93 Eclipse. Let me know if this helps :)
most generic pre-gabs tend to be 1.75cu ft, however to be properly tuned, you need the T/S parameters and/or tuning frequency.
Look around on the net, you may get lucky. Lanzar does not have it as a download on their page. Maybe a call to their customer service would net you the information!

I wrote it in my solution to the original question.
You are shooting for a 4 ohm load.
so a single 4 ohm driver, a dual 2 ohm driver, or (2) dual 4 ohm drivers will do the trick.
Bridge the amplifier @ 4 ohms to get the most power.
I suggest we go for 2 ohm to preserve the amp and not heat things up so bad.
Your Subs are Dual Voice Coil(DVC) and 2 ohms each coil. I am going to tell you the wiring to insure you get balanced response from both Subs. We will wire the Subs Voice coils in Parallel to make them 1 ohm each. Then we will wire the Amp to the subs in series to make the total load on the amp 2 ohms. When you have series to both subs each sub gets the same current.
Example of my coding :SUB1VC1+ = Subwoofer 1 Voice Coil 1 Postive terminal.
SUB1VC1+ to SUB1VC2+
SUB1VC1 - to SUB1VC2-
SUB2VC1 + to SUB2VC2 +
SUB2VC1 - to SUB2VC2 -
AMP + to SUB1VC1 +
SUB1VC1 - to SUB2VC1 +
SUB2VC1 - to AMP -
This should give you a good repsonse.
Adjust your Bass Gain down very low at first. Also cut you LPF to about 60 hz. Crank up the volume on a bass test Audio track, Adjust the Bass Gain up unitl you get distortion. The turn it back a little. This is proper setting for your Gain.
