Thanks for that positive reply sir. Indeed capacitor needs to be grounded based on my research.

Some questions pa po.

1.) how do i connect my subwoofers to the amp? because i'm confused on the term "bridging" kasi yan yung mostly na sinasabi sa akin. do i need this kind of connection or should i just connect it to their respective channels kasi medyo di malinaw sa akin on how to connect these.

2.) Is capacitor only needed on the sub amp or is it alright to connect them to the whole system? (excluding the HU of course)

3.) Do i really need a capacitor for this setup or it'll just run fine without a capacitor?

4.) Comparing with the capacitor and no-capacitor setup, How fast will the battery drain?

5.) Do i need to charge/shock the capacitor before using it?
