HO Alternator or Capacitor

ok so the local shop is going to get in a replacement sub in about a week, and i'll have them throw that in there.  now im about to go to school so i dont want to blow any more of these subs because i'll be an hour away.  They keep trying to sell me a frikin cap and i know thats not gonna work.  The shop turned the gains all the way up...do you think that is the problem?  I know thats not good, and they need to be set correctly.  If i took it to a professional and had them set the gains correctly do you think my subs would stop blowing?  or do you think its a voltage problem like the shop thinks?

Set your gains correctly.  A cap will not solve a voltage problem.Support the12volt.com

yeh thats what i thought.  i wish there was somethin i could do regarding this shop i've been working with.  they really don't know too much about what they're doing.  one thing i've been thinking about...what does a bad ground do to your system?  just wondering if that could play a part.  also, do you  think i should take it to best buy and let them do it or should i try it myself?

ok i will definitely do that. 

well things just keep getting worse in this ongoing saga of mine haha.  i just blew the only sub i had left, so now i have nothing.  they keep saying that it's probably bad voltage, and a cap would definitely help.  i just dont buy that though.  today they mentioned that it could be some distortion coming from having the factory head unit in there, and i think there might be something to that.  i also need a bigger alternator too cause the amp is going into protect mode after several minutes of play.  so, does anyone think that the factory head unit could be causing some or most of my problems.  if u need more history on the subject, check the first two pages.  i really need your help on this one fellas...i appreciate it

Did you get your gain set properly?Support the12volt.com

the shop turned them all the way up to begin with.  they didn't set them properly, and once they replace the subs im going to take it to best buy and have them set the gains, or i'll do it myself.

Then I hope that replacement sub is free since that shop destroyed it!

A shop around here destroyed one of my subs and they replaced it for free. I was happy.
