  1. the AMM1 is measuring live, so if there is no load there's no measurement. if you have a resistor pack you could use the AMM1 to help set gains. resistors with a high wattage rating become very expensive very quickly. i'd just fork over the money for a DD1 or DD1+. now if you can get a measurement without a load, that's beyond me of how you could make that happen without a resistor of some sort.
  2. to answer your question, you're going to need to plot the sub and enclosure design in something like BBP6 or Term-Pro.
  3. do a 4" aero port, tune lower like 28-30hz. you'll have a wide playing range and get low.
  4. no real issue, may melt some of the jacket near the solder joint b/c the gauge of the wire.
  5. no matter what information actually get put out there, people will still buy CCA wire. 2 main reasons, 1 is money and 2 is ignorance (whether it be willing or unwilling). too many people use the excuse of "i'm not good at math" as a reason to be stupid when it comes to anything that has a number. same applies here. companies that make CCA wire are more at fault than the consumers. they advertise fluff numbers to push product.
  6. is the radio cutting power or just the amps? if you unplug the RCAs from the back of the radio, same issue? what phone are you using for BT?
  7. mount it to a piece of ABS plastic then make an arm out of the ABS that'll go under a seat bolt.
  8. quit drawing and shaping by hand. I can't draw to save my life. give me something that holds it's shape and I can draw pretty good. get something that has shapes you want and use them as a guide. making templates or beauty panels is all about combining shapes and making them flow together. try the template below as a starting point. https://www.michaels.com/artists-loft-house-plan-template/10316186.html#q=template&start=8
  9. the 501 has time alignment and speaker location level adjustment. use them and see where you're at.
  10. a wire that has 12v only when the vehicle is running
  11. https://www.sony.com/electronics/in-car-receivers-players/mex-xb120bt/specifications
  12. even if your amp did create a dirty signal at .5 ohms compared to 1 ohm, you can't get rid of that. that's an amp issue. the DD1 is helping you get the gain matched to the signal output from your source with overlap if desired.
  13. considering all things equal, I'd go with more cone area especially in this case. while you're considering depth, I tend to lean toward large subs. I just find that larger subs tend to have a more appealing sound when it comes to low end extension. is their a reason you're not considering 12s?
  14. Audiocontrol's Three.2 and Four.1 have a parametric sweep of 40-80.
