JBL - Celebrity150 Single DIN Receiver - Black

Thank you for your inquiry. Yes, our JBL Celebrity 150 will fit your 1997 Toyota Avalon, however you will need a dash mounting kit to fill the gap and a Toyota-specific wiring harness adapter for a clean installation. Take note that if your Avalon has the premium factory JBL sound system, it won't be compatible with aftermarket stereos. So during installation, you will just need to either bypass that old amplifier entirely or use a specialized integration harness to connect the new receiver to it. You may visit your local Toyota service center for further assistance.
