I just didn't have time to really troubleshoot it last night.

My sub amp has a feature to turn on when it sees an audio signal, and if I set it to that, the amp doesn't turn on, so I can only assume there's no signal coming out of the head unit.

I can apparently play a test tone and check for AC voltage on the RCAs when I get back too.

Sounds like it's an issue with the RCA outs but out of curiosity, is there a sub volume control? Is it way low?

Yeah, there's a sub gain setting. I bumped that up and still nothing.

Try the rear outputs and see if you got bass.

propav8r · 06-09-2022, 08:15 AM

The firmware update fixed the sub output issue, time to button up the rest of the interior.

Well the ordeal is finally done. The new carpet came from stockinteriors.com. It's a little baggy in places, mostly around the shifter hump where it goes down on the left and right, but it's not too bad. It'll probably form a bit better with some time and heat.

I'm so, so happy with the stereo. It sounds really good to me. Probably not like audiophile quality, but it's far and away the best stereo I've had in this car, ever, and better than any other 240 I've heard. Having a high pass filter on the amp for the door speakers is a game changer.

Excellent

nice job Jared

Did you need a black plastic cover for the interior rear view mirror? I noticed in the IG pic that it wasn't black, and now I see what's going on under there....some sort of something covering over what I assume was not a black mirror trim cover?

I'm pretty sure I have a black one from a Turbo if you want it.

Ah thanks, I covered it in the same printed burlap that I did the sunroof panel in. I’ll probably just leave it as is, thanks though.

Looks like I've inadvertently been presented with a solution for my steering issues thanks to the Buchkas, so that's neat.

Unfortunately my rear door speakers are already dead. They were Alpines that I put in circa 2011 that seemed okay, but had been used for an awfully long time. I also briefly mixed up what a high pass and low pass filter did for the rear channel, and I think I damaged them then. Oh well, putting in a pair of Kenwoods this evening that handle more RMS power anyway. No huge loss there.

If the weather's decent this weekend, I may just go ahead and throw on the QSRCs I've had on the shelf for months, and maybe re-plumb my brake system if I can find the parts I need locally.

The brakes on this car have always been suuuuuper rear-biased, to the point that the rear gets real squirrely under hard braking, and I can't hold the car still if I'm doing a burnout.

I think I'm just going to re-plumb the whole thing and get rid of the Volvo junction block. Just drop off the master port for the front brakes to a T, and split left and right, and a line from the master port for the rear to a proportioning valve, and then back to a T on the rear axle. Running off the factory junction block and having two rear lines to the back through the factory bias valves just seems pointless.
