hertz rear speakers

[miguel 32]

Hi All
I have the alpine halo 9 fitted in my van with with the T6.1 Alpine door speakers and tweeters however i have two hertz rear speakers installed but the output volume is very low compared to the front speakers has anyone else noticed this and if so did you ever resolve it?

I only have the OEM head unit and added rear spekers, so not sure on the Alpine head unit but can't you adjust the front/rear volume via the fade controls like the OEM headunit?

I did try that I just thought the rears would match the front speakers without having to adjust them.

Check to see if the frequency on the rears has been set high. On the alpine I found resetting the unit to factory setting and start again fine tuning it, there is lots of adjustment on the Alpine unit.
