My new system

sound quality

not sound quality, sound pressure level, I've just made a mistake ... sorry ...

thought I copied sound pressure level, but it was sound quality :S

you could also go the route of the Diamond Audio TDX series subs Quad L Handyman services

Who is doing the install. You or professionals? For 25oo dollars and since you wanna do spl Id follow a simple rule of thumb. There is no replacement for Displacement. I am assuming you wanna keep your back seat so everything is gonna have to fit in behind. I know for a fact you can fit 4 10's behind the seat of the accent in a sealed box provided they are optimized for small enclosures. I think Eclipse can fit in some small enclosures and as far as exact model numbers go I think Forbidden can cover that with you. Once you know what kinda drivers you want then you will know what kinda amps you need. If you are gonna use your alpine deck and will probally use 2 or more amps to run the subs I would suggest getting a line driver. I know Phoenix Gold makes a good one thats about 150 bucks canadian, PLD1 I think is the model number. Thats gonna boost you voltage going from the deck to the amps. With the budget you have I have to major suggestons. 1st let professionals do the install unless you are absolutly sure in your abilities. Beginners probally shouldnt be learning on 2500 dollars worth of equipment. Second upgrade your altenator. Your not gonna be able to successfully compete without getting more ampreage at your disposal. Once I get some specs on drivers Ill make a couple suggestions for amps. It would help to know whats avalible in your area of the countrydouble-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

but I want a great sound when I'll be driving ... For the competitions I want to try, yes it is spl, but for the other days, I want a great sound in every aspect ...
