hey i got an apline type x sub in my car and it was loud as hell with my stock bose head unit. i changed to an alpine head unit and drew rca wires from the amp to the back of the head unit and now it has weak power. if i use the old rca wire they drew from the stock sub its loud again. any ideas wat the problem is?

 

reset the gains on your amp.

 

but when i use the old rca wires the original ones from the stock sub the subs hit hard but when i use the ones that go to the back of the radio they dont hit hard at all.

 

Read post #2 again.

 

I understand, the amp is just seeing different levels of input from the RCA's between the original wires and your new head unit. You just need to reset the gains to match the new input signal from the HU.

 

oo ok. i thought that it might have been the rca imputs on the HU. ima try that tomorrow

 

Very nicely put AscendantMax .

 

......

 

i tried playing with the gain and nothing. it is still very low. do u think it might be the radios inputs?

 

You mean the radios OUTputs

2005 Alpine..teh ghey preouts.

 

i know. i plug in the rca wire and its weak. do u think its the outputs?

 

settings within the head unit perhaps? how did you set the gains?

 

What kind of amp is it. If you have a an alpine amp switch the input from high level/voltage to low level/voltage
