  1. If I’m understanding you correctly, the tuning will probably come out lower than you intend. If you could post a picture of your design that would help.
  2. What is means is that the manufacturer lied about how much power its amp produces. It it puts out 1000 watts at 1 ohm you will be lucky. Its not physically possible for it to put out anywhere near 2000 watts on a 100 amp fuse.
  3. That layout should work fine, just be sure to reverse the polarity on the inverted subs so they are in phase with the others. As far as which direction your port faces, it somewhat depends on what vehicle you have, but usually pointed back or up is best.
  4. If your bracing is really good you don't absolutely need it. But it would be a good idea of you can make it fit. It lets you flush mount the subs too, which looks nice IMHO.
  5. Yeah, are you planning having a double baffle? You will want bracing as well.
  6. Yes, its needs to be the same, or greater. Also, the effective length of your port is going to include going around the corner at the bottom like this:
  7. What's your net volume per sub? Just from a quick glance everything looks good to me.
  8. The red area is going to count as port volume. Quick question for you, what is the length of measurement A and measurement B in your design?
  9. Replaygain is like an improved version of MP3gain, at least that's my understanding. Replaygain is calculated on both a per track level and per album. The per-album level is nice because sometimes producers intend some songs on an album to be quieter than others, so replaygain preserves that. The technology works very well, its applying the replaygain in the first place that's the hard part. It doesn't actually change the audio of the track, it just adds a tag so the audio player knows the proper amount of gain adjustment to make. I use Foobar2000 media player with a plugin to apply replaygain to my music files. I'm an iPhone user so I then use another piece of software (MP3Tag) to convert the replaygain into Apple's native SoundCheck. SoundCheck works just like replaygain in that it assigns a gain adjustment value to each track. The algorithm for replaygain works better so that's why I start with it and then copy its calculated value over into the SoundCheck format. From there my phone does all the rest. Admittedly, it's kind of a convoluted process, but you only have to do it to your music once and the results are worth it to me.
  10. As long as the port is properly implemented, there really is no performance difference between a slot port or an aero port.
  11. Changing the net volume of a box changes how it sounds. That may be good or bad depending on what your goals are. There isn't one "right" or "best" box spec.
  12. Your understanding of the problem is completely correct. One thing to keep in mind is that having that much overlap only matters when you are playing with your headunit set at its max volume level before clipping. If you aren’t playing at war volume all the time you are probably fine. If you DO play at war volume all the time, I would suggest caution and advise you to do some things differently. What I do for my own music is I pretty much only play music off my phone and all my songs have been gain adjusted using replaygain. Replaygain sets everything to about -5 dB max so I can then set my amps with -5 dB of overlap and I have no clipping.
  13. You need more space. The dimensions you gave aren’t going to provide enough net volume for two 15”s.
