Answer 1

Ehhh, 150 dB's is very enclosure dependent, to get that high up you need to find a box that will peak at about 50-55 Hz. tuning that high will only be loud to the microphone, not to your ears. If you want loud to your ears you need to tune to about 30-35 Hz. In a trunk car with a box tuned to 32 Hz. with subs and port facing the trunk you till peak at about 40 Hz. that is right in the middle, its a good mix. And DD's are very amazing woofers, but with only 4K RMS you won't break 150dB's with that box. Good luck!

Answer 2

Trust me, I believe you can get "atleast" 150 easily, and yes that will work, and you will really wake up "not the "neighborhood", but the "CITY"...lol, no joke.

I know!!!...

Hope I helped.

Answer 3
