Should I upgrade the stock speakers with Alpines?
I read on the forum here some Alpine SPS-410 is a great speaker and changing out the speakers in 4 doors would improve sound quality (I got the standard sound package).
I called some car audio shops for installation of these speakers (got them the speakers from Internet), and one of the places said it won't make a difference and if I want better sound I should also put a better amp.
He said either keep it stock or change it all.
Is he trying to sell me stuff or give me good advice?
