Mr DeeBeez Posted October 7, 2014 Report Share Posted October 7, 2014 I posted this in my build log, but thought i would get a better response if i made a thread about it. I just put in my new box with 2 hdc3 10's. they are powered by a rockford fosgate p1000-1bd amp. (i know they are very underpowered. have bigger amp to put in once i get time) when i started playing them, it looks like they are out of phase. also, i get a lot of port noise. can anyone help me figure out why? also, the box was designed by joe x, so i dont think the box is the reason for the port noise here is a video of it Fi Team 18's (4) Crossfire 16k Crossfire 400.4 & 800.4 Pioneer AVH-X491bhs 140ah cmax CES 320's (2) Link to comment Share on other sites More sharing options...
tacomaguy1 Posted October 7, 2014 Report Share Posted October 7, 2014 Take leads going to amp from subs Touch to batt + and - Subs should move same direction. If not out of phase Team Flex Issues Link to comment Share on other sites More sharing options...
Mr DeeBeez Posted October 7, 2014 Author Report Share Posted October 7, 2014 i only have the battery under the hood right now. i cant reach wire from my trunk to my battery and still see the subs :/ Fi Team 18's (4) Crossfire 16k Crossfire 400.4 & 800.4 Pioneer AVH-X491bhs 140ah cmax CES 320's (2) Link to comment Share on other sites More sharing options...
Kranny Posted October 7, 2014 Report Share Posted October 7, 2014 Take leads going to amp from subs Touch to batt + and - Subs should move same direction. If not out of phase also dont hold the sub speaker wires on the batt + and - for more than a brief second. subs moving out = in phase subs sucking in = out of phase.

Kyblack76 Posted October 7, 2014 Report Share Posted October 7, 2014 Ill bet a million its just the camera/video doing it. that said, like timmy said, use a 9v bat, and pop test them. But, ill be your fine. the camera is playing trics on your eyes....

Mr DeeBeez Posted October 7, 2014 Author Report Share Posted October 7, 2014 its not just on camera. in person it does seem like one is moving more than the other, and they arent moving at the same time. ill try the pop test. also, if subs are out of phase, would that create port noise?

tacomaguy1 Posted October 7, 2014 Report Share Posted October 7, 2014 It'll cause a significant decrease in output Team Flex Issues Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted October 7, 2014 Report Share Posted October 7, 2014 I wouldn't think you would get port noise if the subs were out of phase, since they would be canceling each other out. Like others said, I bet your subs are in phase, but do a pop test with a 9v battery to know for sure. Did you round over the edges inside and around your port? Sharp edges will give you port noise.

Mr DeeBeez Posted October 7, 2014 Author Report Share Posted October 7, 2014 did the pop test. they are not out of phase. and triticum, no i did not. i have an angled piece of wood in the corner of the port, but did not round off anything. will port noise affect output? or can you hear it other than when your trunk is open?
