Help! Installation problem!

[BumpInDaTrunk 10+ year member]

I have an 09 mazda 6 and i just installed front and rear alpine type-r speakers.

the front are component and the rear are coaxial, which makes 6 speakers. the back speakers and the front woofers work perfect, but the tweeters in the front have a very noticeable volume difference. the left sides volume is considerably lower then the right. I went back over my installation and I can't find any problems or differences. It is not the tweeters, because I tried a different pair.

Ive figure it could be one of three things...

1. My install.

2. Mazdas stock stereo and/or not having an amp installed yet.

3. Faulty speakers or crossover.

Anyone have any idea what could cause this? I plan to get an alpine pdx-4.100 installed tomorrow and call alpine to ask for troubleshooting help, but any ideas would be much appreciated. It is very frustrating to have this problem after all the hard work.

what would that do?

huh? im not sure i understand.

If the tweeters are 'aimed' at different places, then they would appear to have a noticable different volume.

oh, i thought thats what you meant. i actually held both side to my ears at the same time. it def not aiming :-/ i hear an absolute volume difference.

did the components have a crossover? also does it have +3 db? it could also be out of phase

 

[BumpInDaTrunk 10+ year member]

yea they do. The db gain on both crossovers is set at 0 so it cant be that. idk what the phase is or how to change it on the stock stereo. the installation place i brought it to thinks its mazda's stereo, but it was just an idea.

Out of phase meaning one tweet is hooked up + to + and - to - from the HU but the other is + to - and - to +. Worth checkin'.

Updates?

 

[prcwitt 10+ year member]

if you are using aftermarket components with their own crossover then the factory radio should not have anything to do with it the front mid range woofers and tweeters use the same input then gets separated through the crossover

ill have to look into the phase thing that could be it. I got an amp installed and it helped, but the problem is still there.
