[BertzSS]

I have a '23 SS convertible that I am trying to add an Alpine S-A60M mono-block amp with high level inputs and a subwoofer. There is not a factory amp in my trunk. I've read a lot of the threads here and got some contradictory info, but it sounds like the best way to get the audio signal to the amp is to use a t-harness breakout adapter and connect to the radio module in front of the glove box.

I thought that non-Bose meant no amp at all, so I originally bought this t-harness: https://www.amazon.com/dp/B0B6MY22GP...fed_asin_title but once I got access to the module in front of the glove box, it was evident that this was the wrong adapter and as far as I can tell, there's nothing in my car to connect this to. Now I realize that there is another factory amp that this was intended for. (Correct me if that wrong.)

So now, it seems like maybe I need this one LPHGM71 or LPHGM72 but I can't seem to find confirmation on which one or if these will work on a 2023.

I'm hoping that someone can provide some guidance about the proper t-harness or if there's another way to access the front speaker wires. I'd rather not have to go into the doors to get to the wires.

Also, is it better to connect the amp to the front speakers? I've read that the rear ones don't get as good of an output as the front, but I've also read that the rear speakers are just low end and don't perform well, but get the same quality sounds as the front ones. At this point, I'm thinking the rear ones might be easier to access.

Thanks in advance!

I have a 2023 1SS non-bose (8" screen) with the amplifier next to the glove box.

I used this adapter to access signals:








Be sure to check the actual pin connections, mine was incorrectly pinned with two wires swapped and they weren't trivial wires (High speed CANBUS and rear speaker).

The front speakers are the best signal to intercept. The rear signal is weaker with less bass output.
