im thinkin i want to run 2 or 3 audioque hdc3 18" subs. was playing with the idea of tuning 2 of the subs to one frquency and one of the subs to another frequency, if theory is right i would have continuously loud bass on a wide range of tones. never seen this done, would be something different. if i go with 2 subs they'll be tuned to the same freq. im just thinkin out loud here idk if this would even be possible to have the recommended air space. anyways my train of thought is if im gonna go to the trouble of doin a blow threw im gonna build something unique. cant say ive ever heard of a 67-72 with an 18" much less two or three.
