I have the usual complaint for S/A5 sportback owners. Audi pointed the subwoofer at the floor in the boot... Under the spare wheel... Under the carpet.... Under a boot protector... Under a carpet that sits in the boot protector... Under the shopping that goes on top of it all. I'm would like to fit one I can hear in the recess on the right hand side in the boot. Am I better with a normal size 8inch or a 10inch shallow subwoofer? I would like to budget £250 for sub and amp, can anybody recommend a sub and amp that go together for this? I think the amp has to have high low to take a feed from the original subwoofer. Would also like the amp to sit in the wheel well as don't want to lose space in the boot. Will heat be a problem. Any help is appreciated as the, ohm, coil, peak RMS figures have done my head in for the past week.
