thanks!
after study for a while, with limited budget, how about I buy a good quality amp and sub woofer first, upgrade speaker later? is it a good way to do? (save money then do the big task later)
do you have any suggestion for good small amp with 5 or 6 ch (i want put it under front seat) and small sub (also put under front seat)? how about JL HD600/4? or Alpine?
sorry for change the question 180 degree
