Andy Mac this is possibly another one for you... What is the max mounting depth for the front speakers in an A3 8L? I ideally want, the greatest RMS speaker i can find, allthough quality is the deciding factor here (as im sure it is with anyone that enjoys good clear precise music). As an example i have found these possibilties... Magnat Xcess 102 Principle - 2 way coax system Power Handling RMS/max. - 60 / 110 Watts Impedance - 4 Ohms Frequency response - 42 - 32000 Hz Crossover Frequencies - 3800 Hz Sound pressure level - 90 dB DIN-Diameter - 100 mm Outer diameter - 139 mm with grille Cutting out - 94 mm Mounting depth - 48 mm Infinity Kappa 42.7i Diameter: 4" (10cm) Power Handling, RMS: 50 watts Power Handling, Peak: 150 watts Sensitivity (2.83V/1m): 93dB Frequency Response: 75Hz 25kHz Nominal Impedance: 2 Ohms Mounting Depth: 46mm Cut-Out Diameter: 88mm Thoughts & suggestions please. Cheers.
