How’s I going y’all? I need some help. Last week I finally got my blown subwoofer (alpine swt4-10) replaced. When to the audio shop got it installed back into the box and it no longer hits like how it used to before blowing. I have 2 subwoofers and 1 Jl audio jx500/1D amp. They are ran in series if I remember correctly. I would take it back but my work schedule lately has been rough to plan around. Hopefully y’all can help me! Thank you for your time!
