Hey everyone I'm new to this but I'm glad I registered...anyways I got 2 12" kickers in the trunk but I was thinking of adding a new one replacing the stock subwoofer, so basically I wanna put an 8" we're the stock one is placed, but anyone have any idea if this would sound good or would it just rattle too much...cause ill rather just put it in the trunk with a new box I was just trying to save some space..Any help would be grateful..

 

If two twelves aren't enough for you, adding an eight isn't going to help. Get a better box for the subs, more amp, or better subwoofers if you aren't satisfied.

 

Thanks ... I just came from the sound shop and they suggested a bigger box I was trying to save a lil space but I think I might just do that I'm also thinking of replacing the am to get more of a kick out of it..,

 

which kickers do u currently have?

 

I got 2 12 kickers cvr... If I get a bigger box I wanna just add another 12 cause they gonna b the same size as if I had 2...and getting the hifonics Brutus , the sound shop suggested 1700 watt for the 3,12s

 

no, forget adding a sub and more power

That won't help much.

What you need is a better box design

Which kicker cvr is it? post a pic
