Greetings currently own a z v.4 10. It is a 97 Tahoe being ran off of a saz 2500 v.2. It would be more cost effective to re-cone it to a 18". it would cost little over twice as much two add another z v.4 10, but just because it cost less doesn't mean it will sound better. basically I'm after more output. better low end extension. I had it in my cutlass and it sounded great but in the Tahoe I have a lot more cabin space. any suggestions between the two? thanks in advance for the input.

what are you currently tuned @?

And how much more space do you want to give up for a bigger box?

currently 34Hz, whatever space I need to give up for the proper sized enclosure.

I would recone to an 18". More cone area in a single 18" than two 10". Enclosure size would be much larger with the 18".

Will you be upgrading power?

Not going to be replacing amps at the moment.

Recone to an 18

18 for sure.

yeah I was leaning that way from the beginning... 18 it shall be . I can't even imagine the air it will move, that little 10 would make a small draft. lol
