Hello,

I'm getting a new system, and I need some help please. All I need is a sub(s) an amp, and the wiring. I'm building the enclosure, and I already have a HU.

My budget is ~$600, and my goal is to have a system that pounds really hard I have a 2000 Crown Vic Police Interceptor, so trunk space isn't an issue.

At first I was considering 1 18", but I changed my mind because I don't want to fill my entire trunk w/ the enclosure

First, would 1 12", or 1 15" be enough for a Crown vic since it's a large car? I've heard mixed feelings on this.

If it is enough, I'm looking at the AQ HDC3 15" with either an MB Quart DSC2000.1D or AQ 1200D. The other setup I'm looking at is an Fi 15" BL with the same amp- either the AQ or the MB Quart. I'm also considering (possibly) stepping up the the Fi BTL 12". Would the BTL be worth waiting for until I save up the extra money?

How do these ideas sound? I don't have any bias' so I'm open to any ideas you might have

There's two things I'm confused about regarding subs and enclosures:

1. can a 12" sub hit the same lows as a 15 or 18? If so, how do I maximize the volume of these lows, because on my current system (2 kenwood 12's w/ alpine 500watt amp) the lowest note in Put On by Jeezy sounds really quiet and like the subs are being stressed a lot (idk if they are, bc I'm still a noob. but it sounds like it).

2. how do I "tune" an enclosure? I know this probably seems like a basic question, but I'm learning more and more everyday

Thanks

A 12" can hit the same lows given a correct enclosure, but it is generally a little easier for the larger subs to do so. What box are the Kenwoods in now?

Tuning of an enclosure is based on net volume of the enclosure, port area, and port length. There are various calculators on the web that will help you with the calculation.

They're in separate ported enclosures that I built: 21"W x 16"H x 12"D. idk if they're that great, but my subs sound fine, so I'm pretty happy lol. I'm just looking to step it up and get something new
