I have been using a borrowed Kicker KX400.1 amplifier on my 10" Audiobahn 1000N fully sealed subwoofer and it sounds amazing so I finally got enough to get my own amplifier and got a Boss PH1500M Phantom and it sounds like garbage comparatively. I'm not getting the same level of power or range in frequencies that I used to by a large margin.
Is the new amplifier just not as good? Or is there a break-in period for this amp? Or am I just setting the levels on it wrong? I'm relatively new to the DIY car audio field and would love some feedback. Thanks
