98 Porsche Boxster after market radio install

[Arjae986]

Hello everyone.

Í am installing a double din radio replacing a single din which no longer works. Here's my problem I have all the power and ground connected and all the speaker connectors together. I'm getting sounds from the speakers like the beeping sound coming from the unit. I'm just not getting any music coming out. What an I missing here. PLEASE HELP

What year is your Boxster and what stock Porsche radio model number was in your car? Trying to determine if you had a Bose (fiber optic) or non-Bose audio system

Did you use a wiring harness such as this one?

The RCA plugs would got to the amp -- no amp - then buy the basic harness.

I do hear beep sounds from the head unit going through speakers wouldn't that mean that amp is already connected. Also what is the blue/red and blue/brown wires for.
