Hi fellow tsikot member, I want your opinion regarding the following items for Audio System Update for an 08 Nissan Navara:

Pioneer AVH-2750BT
MB Quart FSA 216 Seps
MB Quart Nano Nan116 Coax

currently debating whether or not to put an amplifier or not - if so what amp model do you recommend as per the chosen setup above..

As per subwoofer- also thinking about it..

Working budget is 25-30k

Thanks in advance guys!
