Hi I thought maybe next week to start a new conversion.. because I have just sold my 1000 Watt bandpass adapted to the skisack to a colleague and will also redesign the suitcase room due to a complete conversion. maybe the following idea would also be the solution for all limo riders without skisack. because everyone has the problem that the bass does not come into the inside room. how about you simply use the sheet strips running under the hat rack to strengthen the s cutting sheet behind the back bench flexed out and replaced by approx. 5-10 solid 10 metal aspiration, which then welds in instead of the wide but thin metal strips. solid would be as before, or even more if one would strive for the still diagonally. but one has created such a huge air channel to the suitcase room and if one now 1-2 suitably adjusted Bassreflex Woofer approx. 1-2 cm under this new hat rack, it presses with certainty from the rear quite neatly. as new optical. blind would probably be a 10mm frame made of welded metal ideal that could then be customized with various coverings. would look like before and the problem would finally be solved.. please post pro & contra
