JBL Amp on a 2004 Sequoia

[atomicspin]

I'm moving from a stock six speaker JBL to...something. However, I was told that I "may or may not" need an extra piece that turns on the stock amp. Right now, the stock stereo sends a signal to the amp, thus turning it on. I was told that they won't know if I need it until they do the installation. Does anyone have any experience with this? Is there a way to know if I need it before they do the installation?

Just for notes, the system does have a secondary DVD player for the entertainment system in back.

Thanks in advance for any help.

Are you just replacing the HU or a full system REDO? If you are just moving to a new HU, then yes you will need this extra part, and I am pretty sure it is the expensive one in those vehicles. You can look it up on metraonline.com.

Thanks for responding.

Yeah, just replacing the HU. Is the piece called an "Amp Harness?"

Well the good news is that your vehicle is Pre DATA-BUS JBL systems, so you can get the $20 harness and be fine. Make sure you get a HU that has RCA preouts for front and rear, and not just a sub one. The bad knews is that I didn't see anything that will retain your factory rear seat entertainment (RSE), I would look on vehicle specific forums to see if anyone has solved this issue. It is possible but it requires some engineering I bet.
