Drk_red_Mk5 Posted September 26, 2005 Share Posted September 26, 2005 have you got the right rated fuse in there?or it could be (unlikely tho) youve got a few stray wire strands going somewhere they souldnt be going? hope that helps Link to comment Share on other sites More sharing options...
stuball Posted September 26, 2005 Share Posted September 26, 2005 Have you checked the wiring in the subs themselves. They move out AND THEN the fuse blows or they move out AS the fuse blows? Link to comment Share on other sites More sharing options...
Drk_red_Mk5 Posted September 26, 2005 Share Posted September 26, 2005 Ps. ehst gauge is the power and earth cable? use 4 guage, its the thickest and least resistance. the higher guage, the thinner the wire wil be, so more resistance. more resistance means less current. so as the amp tries dragging more current thru the wire an fuse 'pop'!

RobMk6 Posted September 30, 2005 Share Posted September 30, 2005 check that the power lead is not earthing out anywhere before it gets to the amp, and which fuse is blowing? in the amp or in the power lead? Link to comment Share on other sites More sharing options...
