715 gives alot of output so yes u may mess up ur moonroof
a while back i sold a dd 500 10" [350rms] & box for a customer's xtrail , it caused a bottle water on d dash , side mirrors & RV mirror to shake , imho it was enough for most ppl for daily use .... but if ur going with something more thna 3 times RMS & double cone area of that 510 well ur going to be bass crazy happy but ur xtrail will suffer
u can always come into my store for demos & to discuss some options ........
