will this work 1 18" fl btl

[jtizzle1000 4]

Hello all been reading this forum for a while no w not new car audio but new to ported boxes trying to put one 18" fi btl fl into a scion tc with out taking up back seat. The measurments I have are 40"w 16"h 21"d I would like to tune to 31-32 hurtz. Iwas wondering if this would be enough airspace and if someone could help me with the deminsions I would greatly appreciate it. Oh and also going to power this with an saz3000 sundown if thats any help. And Thanx in advance

impossible.

I own a scion tc and that cannot be done efficiently.

And, the dimensions you gave is not big enough.

Double baffle + sub displacement alone is 5.75 cuft. The port will take up over 1 cube and after bracing displacement, would onyl be large enough for a SINGLE 15", not 18"

Now, if u tell me you want to run a 15 instead... then i can help ya.

Honestly though, 2 12s for daily will be louder for ya than a single 15.

I used to run 2 12s ran off of 2 2200ds in the hatch and metered a 148.0 flat on a tlab at 42hz.

If this is for comp, i would NOT use 2 12s but rather a single 15 so u can have more useable port area.

Well then i would go for 1 15" btl or go @ 12" bl which do you think would be better for a daily set up and drop low and hard inside the car . Thank for clarifying shizzon just wondering if it was possible was hoping you would chime since i already knew u had a scion if u could help me with a box design i would appreciate it. thanks again!!!!!!!!!!!!!!

Sorry iment 2 12"bl

[shizzzon 461]

well, like i said before, 2 12s would be louder than a single 15.

So, 2 12" BLs would rival a single 15" BTL with 3000w.

I have box design charts that show spl levels on a frequency range between 20hz-52hz, typical range for a sub.

I'll tell u what, i'll post all the documents, you choose which design u like the best based on output!

Whatever design you choose will answer your actual available dimensions as they will change depending on design.

Pay attention to the layouts because each document is recorded with windows and doors shut, then windows and doors open.

Also, test box that was used shows a peak of around 33-34hz.

The car was tested in an environment with $550 worth of Damplifier Pro installed in the vehicle. None on the doors. 2 layers on the cabin floor and 3 layers everywhere else in the rear.

Everything shut-

Everything open-

Pick a design that looks pleasing to you.

Pay no attention to the actual Db numbers produced. The test was done on a 100w amplifier. Just pay attention to the frequencies that are loud, stay the loudest, most consistent throughout the range and so on.

I think i like the sub up,port passenger side 3" from hatch door tuned to about 30hz what do u think

[jtizzle1000 4]

sorry i ment 33hz what do u think

[shizzzon 461]

what size battery you gonna use?

I'm gonna have to draw a design for ya so u can have proper air flow

The battery, when looking into the hatch will be on the right side, on the side of the box.

The port will be facing to the rear on the passenger side and will use the entire back of the car at oly 3" back as a loading area.

Fair warning- VERY excessive vibrations are likely to occur with this design.

If you have a spoiler on the car... reinforce it, disassemble the hatch door panels and deaden the hell out of it... over and over and over.

So, tell me what batt u usin so i can see how much u will have left.

ALSO - where is your amp gonna be mounted?

DO NOT mount it in the loading area, it will more than likely get damaged...

You may be able to get away with mounting it on the box on the side in between the front of the box and the back seat.

Make sure you reinforce the mounting legs with something that can absorb vibrations. I use luxury liner pro from www.secondskinaudio.com

I sell a pack of 4 1.5 x 1.5" squares for $8 mailed USPS if u need some.

[jtizzle1000 4]

The battery i'm going to be using is the kinetik hc2400 probably 2 one in the back and one up front probably a little smaller up front and a 250 amp alternator from dc power because I'm also using the saz 100.4 for my mids and highs.And the back is already done with second skin like 4layers i did if i remeber correctly. As far as the amps haven't figured that part out I hade thouht of where u said but not sure yet.

[shizzzon 461]

hey, go to Kinetik's website, if u dont already have one of these batts, and get the dimensions for it and then look to see if it can fit in the right side area of the car.

I would look on mine but all my panels had to be removed for my equipment to fit.

The battery is going there regardless so see exactly where and how it will fit in the right hand side then post back the remaining dimensions that you have available.

The Height and Depth should remain the same, the width is the only thing that may change.

[jtizzle1000 4]

The battery is 13x6.7x8.5 and all my panels are ripped out to the spare tire all plastics in the hatch area only thing you see is deadner

[shizzzon 461]

that's my kinda install,

i guess i'll check my car tomorrow and see if i can get the dimensions.

[jtizzle1000 4]

Thanks for the help again shizzon I relly appreciate it..
