guys,

i changed my amp yesterday to a 1600w 4-chan amp coz my old one not working ade..

the problem is, now whenever i accelerate, there's a slight humming sound (like the sound of someone whistling). whenever i accelerate harder, the sound also follows the pitch of my engine.

before i changed the amp, this did not happen... how do i solve this? hope any of u can advice me on this..thanks..

sorry but what's a suspressor?

yeah, my friend recommended to put grounding wires.. so this should solve the problem la?

spot on.. did the rewiring and the sound disappeared! cheers
