Please guide me,
i am going to replace my baleno stock speakers.
but not going to cut the rear board etc.
so will be installing 6.5" in rear and same in front doors.
my headunit is LG-LAC5900N, which has 53Wx4 outputs.

it is suitable to install Pioneer TS-A1684 in rear board, and front doors both ?
or suggest me any other speakers.
and will they work fine without amplifier, or i have to install a 4-ch amp ?
Thanks n Regards,
