Hi, I am just a newbie in terms of car audio.

Can you please give some recommendations if I just want to upgrade speakers? (Toyota Hilux Vigo Champ 2011)

I wish sound clarity and just decent bass, so I don't think I need subwoofer. Amplifiers also not in my planning.

Actually, I should take a component or coaxial speaker? And I prefer the brand from Infinity and JBL.

Thanks...
