Hello... thinking to improve my car audio... i had done deadening 4 my door2 layer silver pad(2mm) i was trying to improve sound reduction outside but seem to have effect on my speaker.. seem to add clarity to it.. x

so wonder if i go change 4(+2 tweeter) factory speaker to a pioneer speaker 6 inch all 4 door. Pioneer AMP 600w

OR just buy Woofer+Amp put under seat and end of the story..

budget RM500 to 750
