Worthwhile? I was happy with the soundsystem in my old Dmax but these NNBS Bose systems dont seem to have as much beat as it did. Id jsut like slightl better highs and a little more beat. Ive read where some people have replaced the factory bose sub with an 8".

CC05, I agree for sure, it would be better to add some real sound systems stuff but Ive got factory navigation and rear dvd. It would require a lot of money to make all that stuff still function with aftermarket goodies. Im also not an audiophile either, just want a slightly better sounding system. WOrse comes to worse Ill just be happy with what Ive got.
