oh i bought that thing at walmart for like 5 bucks it helps if you needa take you battery out or sumtin

 

oh yeah thanks guys i tried it with the ground wire and that did the trick now i know the both my 2 ch amp (for my sub) and my 4 ch amp (for speakers) both work so whenever i decide to put in my sub i can do my speakers too

 

glad 2 help, also what are the brands on amps you are running?

 

theyre actually hand me down amps but theyre not bad i dont think great for a kid with no job (ME)
but the 2 ch amp is a pioneer gm-x820 760 max watts (i actually think i need more power but i think itll do fine) to power my 12" earthquake magma (also a hand me down) and my 4 ch amp is a rockford fosgate punh 200a 4

so yeah i think im pretty satisfied with those awesome couldnt-be-better-hand-me-downs alls i needa do now is buy the stuff to install everything and build myself a box (which i still do not know how to do in order to utilize the passive radiator disc that comes with the earthquake
