What kind of LLC are you using?

 

i forgot what kind it is but the rca adapter has the ground wires, the gain controls and the ouput wires.sorry if this is not clear ...it's a speaker to rca adapter

 

Aerostar, I liked your crappy diagram! J/K

Doesn't that wiring setup drop your impedence way down, effectively reducing the amp output alot?

Or, are you using after market amp as well to compensate?

 

yeah i have a aftermarket amp to push hthe 12's

 

You need to route the LLC off of the speakers in the back, not off of the subwoofer wires.

 

sorry for not knowing about these thing.can you clarify this for me???

 

Nooo you definitely dont. I ran mine off the subwoofer wires for a few months with no problems. And yea, you definitely need an aftermarket amp...thats why you get the LLC in the first place. You can run em off the rear speakers if you want, but if you took out the stock sub, you might as well use the wires that were running to that

 

i took the stock sub off and used those wires that were on the stock sub and connected them to the RCA adapter but nothing works..?

 

Is it wired like it is on my diagram?

 

i tried it but nothing works.....do you think i have the remote wire hooked up right? b/c i had a friend that hoooked up the rem. wire to the radio fuse. btw do i have to mess with the original factory amp???

 

Doesnt your amp have a light on it? If the light is on, then that means the remote turn on wire, the power and the ground are all hooked up (however, the power and the ground may be hooked up poorly, which you'll find out when the sub actually hits).

 

yeah the amp power is on....then it boils down to hooking up the rca wires to the old fact. sub wires...i think the old amp blew or something. maybe thats why it isn't on

 

maybe your stock amp is messed up. if you tap in after the factory amp, then maybe thats your problem. you also are tapped in to something that is amplified (your factory amp) witch is running into your other amp(your aftermarket). from what i know that is not a good idea. eventually somthing will give

 

yeah i think so too.....i'm getting frustrated...i'm gonna go ahead and get a cd deck then
