I kind of axed the triple IDQ setup when some one on the cardomain. said that 2 rl-p 12's which would have about the same output as a idmax would only be marginally louder than a Ascendant Audio Avalanche 15 since the cone area of 2 12's 1 15 is only about 30% larger so and the ava has more excursion so it would be safe to say that it would be louder than the idq's and easier that wallet. only problem with the box i designed (23" deep) the enclsosure would ony be 2" from the trunk latch so i might have to point it forward and seal of the trunk of the enclosure. but to the point i was wondering what would i need to cut the sheetmetal in the passthrough (basically make the hole 2-3" taller and square off where it curves in at on the top) in a b14. i took the plastic stuff of and looked at it and saw where the metal is doubled up at in one point and how it's bent and i don't quite think tin snips are going to cut it.
