start up issue

[waterman412]

alright, whenever i start my car it tries cranking but wont start, and the lights kinda flicker. if i give it gas and hold it around 2500 for a couple seconds its fine and runs fine till i shut off.i JUST replaced the battery like a week ago. this problem didnt start till after i took my system out. i dont want them in there anymore, ### im tryin to sell it , but i want my car to start to.
thanks

Probably a bad ground. I assume you messed with the battery cables whilst removing the system. Just pull the cables off the battery and clean them up with a battery brush. See if that helps.

just did that.right when i read what you left me. it helped alittle but it still stalls out when i start it.

you think it may be an unrelated issue?
