adding more subs

Get a high output alt (200 amps +) new batter (Optima) and tear out the rest of your car. Build a wall, put all 8 of those 12"s and stand outside of the car with a remote, or inside with a vomit bag. Two of those BP1200.1's is ungodly... i'm lovin it."I don't play games. I play Nakamichi and that for real yo" - Probably some japanese kid said this in the early 80's trying to sell stereo out of his trunk lol.

lol ya my setup right now is uncomfortable so i just want it to be retarded loud. I just find it hard to believe that my 4 12's with 1200 watts can get louder then 8 12's with 2400 watts in a sealed enclosure. wouldnt i get 6 db out of the 8 12's and only around 3 if i ported the box with the 4 subs? Also would i need an extra battery of just replace my stock one with like a yellow top? im not gonna be playing it without my car on soo.

anybody?

Depends on where you port your box... There will be a peak (high Q) tuning point, where you could get as much as +12dB at one frequency... Do as DYohn suggested, download the FREE WinISD, figure it out, plug in the numbers, and build your box to do what you want it to do... Sheesh... Kids these days. They want everybody else to do for them... It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

What kind of car is this in, wan what kind of subs are you using?? 8 subs need a hell of alot of space, even 4 need a lot of space for that matter. Also have you considered getting four better subs (maybe 15s that handle between 600-1000W apiece) and running two off each amp.

ya i have a dodge dakota ext cab, i took out the back seats, im assure that i could fit 8 soo.Now are 15's gonna be louder as like in db wise or is it just gonna hit lower frequencies?

4 12's ported with 1200 watts or 8 12's sealed with 2400 watts. Which is going to hit harder?

Like was said before, it all depends on the ported box. You CAN make the 4 louder. Personally I'd do 8 ported.Nik
