AA98hoe Posted July 6, 2013 Report Share Posted July 6, 2013 how can polarity be a problem if 1 sub is in and each sub has its own chamber? unless I misread On dvc subs you can have one coil in phase the other out of phase an it will heat that sub up quicker than shit with hardly any output ..

Guest Posted July 6, 2013 Report Share Posted July 6, 2013 I have 2 zx2500's but the birth sheets are more then 200 watts apart and Ill be pushing them each to their limits really more than 200 watts? so what? tune the amps with an oscope/dd1. find which amp has the lower AC voltage output, then lower the gain on the one that has the higher AC voltage output til they match. done. edit: now knock that center partition out and put bracing. shared airspace > separated.

Zak Massey Posted July 6, 2013 Author Report Share Posted July 6, 2013 I'm fairly new to the car audio world, I had just heard that if the amps ran different powers then you should have the subs in seperate chambers, so I guess ill be knocking out that bit and open up the airspace some.

SnowDrifter Posted July 6, 2013 Report Share Posted July 6, 2013 Do the pop test with a battery. Both subs should move out.

Zak Massey Posted July 6, 2013 Author Report Share Posted July 6, 2013 Okay guys, my polarities are all correct.

Jessica Posted July 6, 2013 Report Share Posted July 6, 2013 If you are runnning an amp with to each sub then you need to gain match. Simply unhook the subs, put a DMM set to ac volts to the speaker terminals and adjust the one with the higher voltage down to match the lower one. I don't know if the zx2500 is strappable or not, but that is also an option. Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

SnowDrifter Posted July 6, 2013 Report Share Posted July 6, 2013 Measure your box and post the various dimensions here. sometimes it happens that what you build might have ended up being different than the real results ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
CleanSierra Posted July 6, 2013 Report Share Posted July 6, 2013 What IS your voltage like at the amps? Id test that with a DMM. Also, you need to have those gains set properly on that amp. Get in touch with someone with a DD1 or O-scope. Then if you do the shared chamber box, you need to gain match the amps. Im not the one you want to try to troll. Just a fyi for you.
