I just put in a new 12" kicker sub with amp on it. I hooked everything up. The ground wire is hooked. I hooked everything I needed I think. Im running it to the battery for power and I hooked it up the the back speakers with the one wire. I turn on the music and you can hear the sub, but barely. The amp light is on and everything. It is just not hitting. Please help me out.

 

on your head unit is your sub turned on, because on mine i have an option to play music with it on or off, also make sure your bass is turned up and not on -6 or something

 

maybe you have an amp that's not powerful enough...

 

but the amp came with the subs screwed on it. plus it has been in another car before

 

it sounds like your problem is that you're trying to get the audio signal from the back speakers. You need to get a head unit that specifically has an RCA port for your sub. You can also try raising the "gain" on your sub to see if it helps at all, but I would suggest just hooking it up to radio instead of the rear speaker. Also, do you have a remote wire running from the head unit to the amp? That would also keep the sub from working.

 

^ahhh stole that one from me... yeah.. are you pulling your sub from your beack speakers or actually using the rca's?

 

hahaha sorry buddy... Thats really the only thing that stuck out to me

 

dont worry... good q though would explain the lower volume specially if the head unit handles the subs separately

 

actually it was just a bad connection. sub works great now just the way it is hooked up

 

sounds like someone is gonna need a rewire if they hit a bump too hard. [8D]
