2002 Tl Bose Stereo
 

HEY, i just bought my 2002 tl type s and i wanted to install an amp (rockford bd1000) and 2 12s(haven't bought them yet) without changing the HU, i know i have to buy an LOC but what i want to know is how do u install in, my car has an stock amp so do i tap the wires before the stck amp or after also do i tap the wires in the stock subwoofer or speakers, PLease HELP, really confused

hook it up after the amp.

Hook it up to the subwoofers or speakers

If you have a sub control on the factory deck than hook it up to the subs but if you don't than it doesn't really matter.

can i just cut the end of the rca and hook it up to the sub signal befor going to the stock amp and the rca in my aftermarket amp
