Alright my friend wants to be crazy loud, so hes thinking of going with a btl. but he has a 2004 jetta and doesnt have enough space to go ported. do you guys think that with 1700 watts rms going sealed would be fine? or are btls not recommended sealed?

WHY WOULD YOU DO THAT?!?!?!

Do a 12BTL ported, or a 15Q sealed.

yeah thats waht i was trying to explain to him, and is getting a 3rd magnet worth it? or have people been just buying the bare minimum and it still bumps as loud as an mt

and would giving a FI q be safe to put 1700 watts to if you watch the gains?

do you think my friend would have to upgrade his stock speakers if he were to go with the 15" q or the 12" btl

The BTL's work in astonishingly small ported enclosures due to their low Qts/Qes, low Vas, and low Mms. How much room does he really have? I really would not recommend using a BTL in a sealed enclosure; optimal performance will definitely be found in a bass reflex enclosure.

Any driver can be fine if you watch the gains. There is not really a need to put 1700W on a Q series driver, but I'm sure you will be fine as long as you are careful. Music is so dynamic that it is hard to define when you are using too large of an amplifier, but again, you can adjust the gains

accordingly.

Would he have to? Well, no one has to, but I would highly recommend it. I personally find midbass more appealing than subbass, so that would be my biggest concern, but it depends upon his musical tastes.
