holy crap....this is a little more involved than i thought. I thought I knew more about mobile audio than I actually do. Looks like I've got some studying to do if I want to see this one through. I'm finally up to par on my low frequency knowledge but it's time to step it up on 70hz+. Active is probably the best way for me to go since I'm gonna be using a lot of audio control stuff. I've got factory nav/steering wheel controls etc that i'm gonna keep and i'm not using an aftermarket head unit. unfortunately all the audiocontrol stuff i've been told that I'll need will run me over 1K....

that's a good idea....i think i may try that I was just kidding...20Hz is the threshold of hearing & that's at about 70dB so I wouldn't want that system anyways

that's a good idea....i think i may try that

Ok...that's understandable. So how is going active different/better than just using passive x-overs/component speakers?

I'm trying to learn more about setting up my mids/highs & I've been reading a lot of threads about "going active." I think I've got the gist of what it is and how to do it (kind of) but I'm trying to figure out what the benefit is. Is going active and using the HPF & LPF on the amp better than just using the passive x-over that comes with ur components? The only thing I can think of is maybe it's cheaper to buy a midrange and a set of tweets than buying a nice component set....Somebody wanna help me understand this a lil' better?

On that note, the amp is either gonna be Memphis MCD-M1500 or Kicker ZX1500.1. Both amps usually bench around 1700 or so (@14.4). Would that be enough for two 15" Q's?

Is a true 1500 watts too much for a single Fi Q 18" to handle with the BP option? I was trying to decide between going this route, or going with a dual 15" setup with a 2500watt amp...I'm leaning towards the 18 since it'll be cheaper and more electrically friendly. (vehicle is a dodge magnum)

For both options the box will be around 7.5 cubes after port & displacement. for the 15's tuning will be 32ish Hz and 28 Hz for the 18. For both options the amp will be Exile 2400.1. For 15's 2400 watts @ 1 ohm. For 18, 1600 watts at 2 ohms. For overall musicality/output, which would you rather have? .....oh yea, vehicle is a Dodge Magnum.

Why is the recommended tuning frequency for the Q 18 so low?
