Help Replacing HU
Replace HU with Alpine CD HU
Upgrade stock speakers keeping the same sizes (for now)
Keep stock amp
I’ve heard the stock HU is just a cassette player with pres out and the controls for the tuner and amp. The tuner and amp is behind the passanger seat? Or, is just the amp back there?
Concerns and questions:
Can I simply tap into the stock cassette preamp line out going to the stock amp?
Can I connect the Alpine antenna and power for antenna at the dash?
So at the dash I need:
Power
Ground
Ignition
Pres out going to amp
Antenna
Power antenna
The entire preamp for the existing stock system must be in the HU right? So there must be one master preamp line going to the amp?
Thanks so much for your help
