Okay when I first installed the sub it wasn’t play at all then I went in to the box and figure out my problem, but my 800watt can’t even play the sub, and every time I get the normal d12 sub they blow in the first week at this point I don’t know what subs to get from yall to last a month+ I can’t fit 8s into my box because it’s a 2009-2014 box, do I just keep buying d12s and keep blowing up or what, im very upset about this I would like a refund of my set up or send me more then 1 12 at this point and u may ask is the amp tuned right, yes it’s tuned for 12s only, I’m so confused on what to do now so I got a sub in my truck that don’t play and I got 2 in my room that blown in one month.
