I’m confused

subs volume uneven

I replaced the amp inside of one of my black 18 sub's & when I play them side to side the one with the new part in it is not as loud as the other unit. What do i need to do?

  • Hi Leslie,

    Thanks for posting. 

    I'm afraid I don't have any information on how to service the speaker. I would recommend getting in touch with one of our authorized service centers for assistance with this. 

    Warranty and non-warranty claims are not handled here on the forum but I can point you in the right direction. Here are a couple of options that you could choose from:
    • Submit a Warranty or Service inquiry with our Technical Support team by logging onto the Alto Pro Audio Support Page.  Select Warranty or Service Inquiry from the drop down menu.


    I hope this helps!  Let me know if you have any additional questions.
