Dear memberz in ICE-forum

I wanna know more how to define good sound. I have changed my car speaker today and i only find it's lounder plus a bit more clarity.

I am  NOW using a AIWA HU, JVC speakers 6X9 or 3X9 ar..hahah   , and one component set AUDIO-something worth RM 300 ( Tweeter, Crossover, @ Front speaker ) please forgive me i am newborn in ICEworld.

What i want is CLARITY of vocals when i hear live concerts or solo performance, not the sharp irritating sound..( which left my ears feeling uneasy today, after i turn up the volume ). And some solid BASS when i play R&B songs.. very rare in hard-metal or feng-tau songs either.

I plan to get another AMP and SUB/Woofer next month as recommended by the salesperson. He charge me RM 500 oh.  He said no need expensive amp, coz AMP is AMP loh. Ishh.. ..    Will it help? I don't wanna buy something not equivalent to my expected result. Plz Plz save me from slaughtering.. .. LOLz
