  1. Try different RCA's and without the PAC, I'd try that first and see how it effects it
  2. If it's the power in your sig that could be 4 sundown x18's making tornados out of it's windows lol
  3. I feel like the only con in the bass amp portion, would be price. Your at a higher ohm load, so higher efficiency to make the power, meaning less eat is created. Higher dampening factor compared to 1 ohm.
  4. Installing a big 3 is not a permanent project. If you torture your gear in this car and it blows, well then you need to spend even more when you get a new car. Best to take care of the gear you have so that you don't have to replace it later on.
  5. That is what I was looking for. Thanks guys. Half of me wanted to just go buy a design from someone reputable, the other half wanted to build 25 boxes, all being nearly identical just 1 variable difference to test for myself what does what and come to a final design myself.
  6. No I am not asking if 45's will do anything. I stated, "If there is a portion however that is larger, how would that effect playback?". I know having a portion of the port that is thinner will choke the port, but how will the inverse effect playpack, port noise, and other aspects of playback.
  7. So I recently built a box for my 2 X-18's. It was a really rush build to just have something since I blew my old subs and something to just break them in. This is the first time building such a large port in a box, last several boxes all used aero's too. But with all of that, when it came to the port, there was a huge difference in width from the center of the bend and the actual width. I made a 45 to compensate the difference but it still made me curious. I know having a point through the port where the width is smaller than the planned width will choke it. If there is a portion however that is larger, how would that effect playback? Here are some pics to explain what I am talking about. This is the width of the port by plan and on paper. This is the width of the bend
  8. How many runs from front to back did you have, and inbetween batts? I have a 280a US alt right now, 1 run of pos/neg to back and a single xp3000 currently on a scv4000 and I can easily drop to 10-11v. Seeing so many mixed answers here lmao
  9. I can't seem to find anything about it. Would be cool to test but it would be an expensive type of test. One thing that makes it hard was well is many amps do not display any amount of efficiency, and if they do it's for 4 ohms. But I am curious if you have a system running 1000w at 4 ohms of resistance, compared to 1000w at a 1 ohm resistance. Would the amps be efficient enough to need such a smaller electrical that the price increase for the bigger amps justify it? I also have another question when it comes to incorporating efficiency ratings to your calculations for laying out your system. If you happen to know an efficiency, where does that come into play when equating? Before you see how much amperage pull, or after? When using power = amp * voltage when you only have power and voltage, looking for amperage.
  10. I freaked out when I saw this earlier. I hope that all the user map settings maps will be brought back too. Income defense, tower defense, dbz sagas.
  11. What amp are you going to be running? You sure it is stable to run that high of a input voltage?
  12. I ordered one through sonic and was refunded a month later saying they had no expectancy of when they will be getting more.
  13. When I do this, I calculate at 3 different voltages. I calculate at 14v, the best voltage to have and were you always want to be. 13v or 12.5v, which is usually were people end up, to make sure that if that is were you rest while slamming you will be fine. Then last at 11v, so that way if for some reason you drop that low, you know if you will possibly risk any damage or not.
  14. Well alright, exactly the opposite of my thinking. That does make sense though. Well, I will build the current design I have and make those changes going low, instead of high come 2nd design.
  15. Really? What makes you say that? I am going to build a box tuned to 32hz first, then depending on how I feel it sounds make adjustments from there. Was expecting I would raise the tuning, not lower it.
