this will be my first time using nightshades but i have used the amps for a while now... i currently run 2 1500 on a BTL 15... the amps are very efficient on my stock 140 amp alt, thats why i getting two more and running the shades as well.

the question is that if i get 5 dekas 1 upfront 4 back... how big of an alt to get to go with em... i will be running close to 1600 watts on highs with 8 selenium 8s and a few beyma or selenium tweets...

also for my box... should i go all four back w/ port back or four foward w/ port shooting to the side...(really wanna 4th order done but...) what will be louder for a trunk car older gm model 70s-80s? if done right... 150s on music should be possible right?

What ohm load are the nightshades?? We had a Jeep on my team that I built with 4--12's and 4--1500's.. We had the same Batt setup.. The amp's strapped at 1 ohm the amp's drew close to 900amp of current. I would get a 300amp alt. His sub's were up and port's back and could do 148.3's at the head and around 150's on the dash.. The 148.3 was with the car off and playing music..

the subs are dual 2's and i will be running each at 1 ohm... can you send pics of the set up?
