  1. Heya, I am getting ready to put a sub in my wifes 2014 Kia Sorrento. It has the upgraded infinity sound system but I need a little more oomph. I have a few different subs to choose from. I have 1 Sundown x8v3, 1 Sundown SA10 v2 and 4 Sundown SD4 12-2. I am leaning towards the x8 or sa10 But am not opposed to one of the 12s. I just think I want to build a bandpass box so as to protect it. I am going to be taking the 3rd row seat out and think there is plenty of room to mount a box and amp under there.  I will be using one of my old school amps either a mtx 225 ho or maybe one of my crossfire 30hc's. I also have a Audio Control LC2 with bass knob so I can turn it down when we don't want to bump. What do you think is the best option for my application? I would like it to be stealth as well as protected from groceries, strollers, etc. 

    Thanks for any advice from a fellow Eastern Washingtonian. 


  2. The secret? Having no space limitations. Obviously, space limitations are almost always present. It often becomes a balancing act trying to come up with a design that has the least amount of compromises as possible. Unfortunately I have no easy solutions for you. If you PM me with your specific situation I may be able to give you some suggestions.
  3. BOX DIMENSION HELP...  Hey how are you... I’ve been looking at your feeds off and on for a day or two and entered as a member today.  You definitely seem to be the go to person. I own a 2009 Dodge Charger I’m using an Orion 1500.d1z amp ... I’m powering two sundown SA-12D4  subs that I’m running mono at 1/2 Ohm

    one of the replies you responded to was to the exact subs I’m using 

    however my box height max is 14” max width is 30” and at that height and width my box total length is probably right short of 30” more like 28” I haven’t sized  the opening for more then 28” in length in order to have it slide in easily. Lol The dimension to get me to approx 32hz . And would it be better to do two separate chambers on a box that is side vented or an open box for the two subs with one vent are there advantages to a single or double chambered box I’ve briefly tried a couple free app software (which don’t all seem to be equal but free I guess is the clincher)  I’m getting slightly different answers could you please help with some accurate dimensions with a non flared side port ? thanks so much 

    Your time and response is greatly appreciated perry smith


  4. Heya, I notice you live in eastern wa and know how to design a box. I live in Leavenworth and could use some advice. I have plenty of experience with the actual construction but designing a 4th order is new to me. Any advice or help will be greatly appreciated. I will be using my old school system from the 90s. The subs are 2 orion dvc 12 inch 2ntense. They will be powered by a ppi pc 2100 and an audio control 2xs crossover. 


    here is a link to their specs



    Here is a link to my first post about the install


  5. I’ve got 1500 watts, I have a Grand Prix 2004. Just trying to get the most spl from a trunk.  

  6. Hello, I have bee reading around and doing research on building a box for one of my 12’s for my mustang. But when I use your port area calculator it tells me that I need about 46 sq inches. I can’t figure out how to do this with aeroports. The enclosure is going to be firing into the cab. The front baffle that’s gonna fire into the cab has to be angled. So, it would be easier to use aero ports. 2.0 cubes on 1600 rms at 32. I want the box to be firing into the cab and I want to seal the trunk out. Would you have any suggestions. 32 w 14.5 h 5.5 longer on bottom compare to top ex. 10 top and 15.5 bottom. The box can be any depth. I can fit box in from inside if need to be. Sorry for the long question. 

  7. Hey i noticed on your fb page one of your box designs has pap woofers. do you have any knowledge of his product or personal experience?

  9. I'm sure most people here have come across the "12-16 sq in of port area per cube" guideline for slot ports and the "9-12 sq in per cube" for aeros. The problem with both of these is they only consider box volume. Both input power and tuning frequency, along with box volume, have a great effect on how much port area you need. This is why myself and many others recommend NOT using those rules of thumb. Online you can find several websites (such as carstereo.com) that have port area calculators using the formulas developed by Dickason or Small. These have a similar problem of ignoring input power and these formulas aren't really relevant for our modern, high Xmax subs. The best solution is to use box simulation software (WinISD, BassBoxPro, etc) to determine how much port area you need based on the specifics of your system. However this is time consuming and not everyone has access to that software or has the desire to learn how to use it well. I wanted to come up with something is quick and easy to use, and should hopefully give a lot better results than the rules of thumb or the obsolete formulas. Here it is, to make this easy I'm using Google Docs: https://docs.google.com/spreadsheets/d/1mwBK02mF-8BF3mxqqB8WG0H0GUbTmgQfpJODlo_0moQ/edit?usp=sharing This is what it looks like: This will probably always be a work in progress, but so far I think it should work pretty well. I encourage everyone to use it and give me your feedback! ETA: Much thanks to SMD member aaricchavez!!! He has revised my spreadsheet to make it look much better and be easier to use!
