4 Audioque sdc2.5 15"s ** box help**

[Twiztidsetup]

Haven't decided on what amp to get yet but im thinking around 3000rms.

I want to get the most out of these subs . Need to know how big and what size port / hz I should tune to. It will be a temp vehical, S-10 extended cab. I have a 8cf box in there already and its only half way up to the seats so im pretty sure I can squeese atleast 12cf back there.

I want the lows but also a high spl reading , so what hz should I tune too?

Also the 4 subs will be facing my back with the port on the very top of the box since my seat takes over the left side too tight, most do for a better spl reading.

Let me know all your comments on this build they all help.

Thanks!

15's , says in the topic

[corona_jeff]

35 hz ... and an AQ 2200

don't those things need at the very least 4 cubic ft. per sub? would you have enough room after porting/bracing? I have also heard that they need to be tuned slightly high

"15-inch subs work in 3.0-4.5 net cuft." ...straight from the AQ site.

honestly bro, if you have to ask how big a box has to be and how big and long a port has to be for 4 15's, you're not even close to being ready for a system of that size

Not to brag but ive had 2 l5s ,2 l7s fully powered, made fiberglass custom enclosures for resale,4 kicker cvr's and 1 mtx 9500. Wired every single one of my friends cars there whole life including mine. I am new to the audioque and im actually going for a score this time and was wondering what boxes are doing the best on the termlab with these.

Btw im getting the Crescendo 3k and wiring it to .5ohm with 3 deka 9a31 batts.

I was explaining to the person above for saying that he thinks im not ready for a system that big. I was trying to get a box figure in my head for some good spl . You cant throw any 4 15s in the same box and have it sound the same. I needed experience on these. Laugh it up tough guy .

Measurements would help, then we can give ideas.

I'd tune from 35-38hz, that should give good spl and decent low notes.
