new owner query

[zsvino]

Hey guys!

New owner of the A90 3.0 Premium(bought it used @ 5k miles) here. So we purchased the A90 about last month and just had the chance to inspect the car yesterday. I found these cables and was wondering if you guys could help me figure out what these are and if they're supposed to be connected to something or not.

The RJ45 cable is coming out of the center console/storage area. I'm not sure what this one is meant for.

Forgive me for not knowing what these are, we are fairly new to the fun-car scene.

Congrats on your purchase. Those cable appears to be for an amplifier. Previous owner may have had sub/amp installed and removed it before selling.

Red is a power wire, blue is signal, brown is ground, rca is to get signal from speakers, and RJ45 is probably for amplifier controller to turn up or down bass.

Is it safe to assume that the OEM JBL subs are still installed in the car?

Thank you for the info!!

are you sure that's RJ 45? looks like RJ 11 which is usually used for telephone in '80s.

it is also used for V1 radar detector for power as well. either way, not standard OEM part.

AFAIK JBL subs only come with JBL equipped audio system. Does your car have JBL audio? It should say JBL on speaker grill.

That is true. I just took notice of it and just assumed that it's an RJ45. LOL.

Yea, it does. I'm just kind of worried if the JBL subs are not there anymore. Thanks for your help!!
