2015 F15 X5 speaker and ambine light

[johnlee1993]

Hiya guys, i just pick up a 2015 F15 X5 this weekend and noticed that the interior x5 ambient light is not bright enough(already on its max setting in idrive and on the dash , i wonder is there a way to increase the brightness? like replacing the Led module or something ?

and is there anyone can point me the right direction of having an extra subwoofer installed in the trunk ? like how do we tap the new amp into the existing wiring ? cheers

regards
