hello guys
i am not sure if this thread belongs to this section.. anyways


i have 2 questions

1. i recently bought a single din Clarion NZ409 and it has
preamp RCA outputs. what i want to kow is that if i connect 2(front right n left) of those RCA cables to Blitzsafe which is going to be connected to AUX in, or w/e is in the back of HU, can it still make the sounds?

2. does 14pin harness have every wires to run a navigation? or is it better to find other wires to tap off?

thank you in advance!
