New Install - Db Target ?

[FiQ150db]

Install will consist of a 16cuft wall with 2 18" fully loaded bl's.

Now my question is with 1.5kw per sub what should be my Db target and what should it be with 2k per sub ?

Just wondering if its worthwhile getting a bigger amp ?

x2, you need to meter it and then decide on a DB target and whether or not you wanna switch something around.

well since your questions need more detail. im going out on a lim and gonna take a guess.

bassracing: might hold a 143-45 db's if your electrical is up to par.

db drags: could get up to the mid or high 40's

this is a ball park guess and i may be way off. type of car, tuning, electrical and install will determine your db's.

I know its pretty generic but would like to know if the extra 500wrms per sub would be worth it.

In detail

Car - Ford Fiesta mk5 Zetec S

Subs - Fi BL 18's Fully Loaded

Amps - 2 x Trutech Hammer H1's or 1 DDZ1 (not Z1a)

Wiring - 0awg Knukonceptz

Enclosure - 16cuft wall tuned to 32hz

Power supply - 3 Nsb90's and 250a HO alt from Highouputalternators.com

With 2 Re mx 12's and 1k per sub in a 6cuft boot install I got 145.2.

That help ?

Hard to say how much it would gain you.

In a similar setup a friend of mine went from 1.5kw per sub to 3kw per sub and gained...... 0.0dB! Heh.

Being a wall in a fairly small car a 150 isn't an impossible target, depends on tuning.

gotFi, you're kinda way off... although you say it's ballpark and there are a lot of things that affect it, it's not hard to do ~145dB off a single 12 on 1000wrms. With 2 18's if you can't manage 150 (or good 140's at some insane low frequency) then either your box sucks or something is wrong with your install.
