i paid a shop to install my alpine f300. The installation went well but the way it was install was just like most shop, using a LOC and running rca to the back. I have no problem with it but i'm reading that everyone agrees the correct way would be just soldering the rca directly to the factory harness and bypassing the amp. Leaving the center channel connected so you won't loose a BT and navi voice function.

i'm don't know much about amp or installation but i have learn alot reading this forum and how our (and amp installation) works.

my question is...

if i remove the LOC, can i use those wires (+ / -) to connect the rca to the amp or i have to tap a different harness.

if that's the case can anyone link me to the amp diagram harness or are they still the same color cables for +/= Rf/Lf/RR/LR thank you.

 

Cant use those. Those are stock amp outputs.

 

Yea, those wires come out of the factory amp, don't put RCA's to those.
Here' the thread with the wiring color codes

i really want to amp my tweeter. I replace them with a high end 4ohm 100rms tweeter, they fitted in the oem location and using their crossover.

my question is, can i wire them with the front speakers (which would make the load 8ohm) and run with my amp.

now my second question is, since my amp is 4 channel (50w per channel) can i bridge them to 2 channel making it 150w x 2. i understand that to be able to get stereo sound i might have to bridge the FL/RL FR/RR giving them 150w x 2. would this work, would i loose my stereo and sound like crap or is this a good idea to get some xtra juice.
