A:Answer. I took both brown wires and ground them to a ground lead wire from the amp. This is what I done with mines. Just make sure the wire is solid ground wire and you should be fine.
A:AnswerYou don’t have to unless the loc is powered. With this, you just need left and right speaker to tie into. You can ground it if you want, but you do not need too.
A:AnswerNeed to know more about your setup to help diagnose the issue.
What vehicle?
What head unit?
What amp and sub setup?
Wiring setup?
And any other details or symptoms you can think of.
High off you have the the LOC wired incorrectly to a set of high output only wires is my guess.
A:AnswerDid it on my eagle vision . you should just grab from one rear speaker if its for your lows . ifnur speaker has two entry points for cables make sure u grab the low output is not an output converter just rca converter note.
