[LatinBimmer]

One question for the speaker genius here:

I have the standar hifi ...if I buy the top hifi or high-end (B&O) speakers, are they p&p? I know I "must" add the amp also, but I won't do that...so, maybe upgrading only those speakers do the improvement enough?

Ps: I'd like to replace center console 4" speaker and rear doors speakers...while My focal speakers for front doors are still in customs since July 24 here ��
