Tapos sir, another newbie question, yung AMF4100s po ba o kahit anung 4 channel amp ay pwedeng i-bridge yung 3 channel o lahat ng channel? Sorry, wala pong idea. Naiisip ko lang po kasi eh kung kulang yung power ng 2 channel na nakabridge sa sub eh susubukan ko pong i-bridge yung 3 channel para sa sub tas isang channel na lang magsshare yung mid at tweeter ko since mga stock lang naman po sila. Salamat po ulit.

Take it from me, there's no such thing as future-proofing in budget head units. Today's feature list may include Bluetooth and USB connectivity but expect head units a decade from now to have features such as Apple AirPlay built-in or digital radio (if ever magkaroon tayo). But as long as nothing breaks down, expect them to still work if ever tinambak mo sa bodega tapos binalikan mo after a few years of storage.

What bridging means is that you combine the output of two channels to provide the effect of a mono amplifier. In other words, you can only bridge two channels - bawal tatlong channels into one. For 4-channel amplifiers, most of them are stable to run double bridged naman. In other words, from 4x100.. you can bridge 2-2 and get 2x200W. This "flexibility" is one of the reasons why I like 4-channel amplifiers over 2-channel and mono amplifiers.

Yun usual diagram dyan is that:
Channel 1 - Right Speakers (tweeter + midbass + passive crossover connecting both drivers)
Channel 2 - Left Speakers (tweeter + midbass + passive crossover connecting both drivers)
Channels 3&4 - Subwoofer (bridged)

Post lang if you have more questions
