Hello,
I have a 2019 April SR+
Version F here. Did the install on my own.
they messed up my shipping, forgot about me or something. It took 3 weeks to receive my order.
Here to report that everything works out of the box. No issues with Fade and Balance like some people
are reporting. I didn't tinker with the dsp. but the trebel was really sharp and hurts my ears.
some install notes:
Careful with the DC/OFF/ACC switch on the DSP.. make sure it stays on DC.
I guess I accidently flipped it, and the sub wasn't working.
My driver side tweeter plug already had something plugged in. I was expecting an empty plug.
I had to unplug it. The passenger side was empty as expected.
I did not disconnect the 12V+ battery when installing the kit.
be careful when undoing the 12V+ battery nut if you are using a wrench that is not insulated.
Do not touch the chassis while undoing the nut. =)
the nav lady and the chimes seem louder than usual. Joe Mode helps.
the kit came with rear speakers, I didn't not use them. My car already had rear speakers.
I plugged them in and it worked.
I notice some strange things, when you get in the car, it takes around 5 seconds for the rear to come on.
it seems like the front speakers are connected to the stock amp, and the rear is connected to the DSP.
when the subwoofer powers off, you hear a big thump.
on one drive, the rear was cutting out. not sure how this is possible if i'm directly connected to battery.
My SOC was around 13%. I will monitor this.
overall, i'm very satisfied with the upgrade.
