Wiring speaker signal to amp

[Raph27]

Hello , first post here after search the forum for a while.

The car is 2005 x5 business cd non-dsp.

I'm trying to add 2 subs, i wire the amp following the guide in the main page, everything is good except the speaker siganl for the amp, since the amp has low level inputs I'll need Line ouput converter, my question is: Can I tap the speaker lines that comes from the radio to the factory amplifier, wire it to the rca cable to connect to the new amp? this way i won't need the Loc, is this correct?

Thanks.

You got it, assuming your amplifier can handle a 5V signal

If your amp can handle 5V inputs you are all set, otherwise you still need the LOC.

Thanks for the reply,

I forgot to ask, where are the speaker lines that go from the headunit to the amp? and colors for right + - etc.

thankss..

You need the wires that go from the radio unit to the amp, and honestly, since I drive an E39, I don't know where your is located.

Sorry!
