Great unit. I havent used all the Alexa features yet.. Im sure i will eventually though.

One thing to think about is that Pioneer has used the same wiring harness on all of the single din head units for at least 10 years. If you go buy a new Pioneer you can swap it for your old one in a matter of minutes just plugging in the new stereo to your current harness. If it doesn’t fix it, you could return the new stereo with no damage done.

I am still using a 2007 year harness with a 2020 Pioneer stereo

yea i had an alpine at first but i gave it to a friend so i bought a pioneer and it was doing good but it ended up not lasting a long time so i bought this pioneer i have now and the same harness and its been working for about 4 years now

Ive had no issues with 4v Kenwood HUs. You can find one fairly decently priced.. maybe even a 5v hu. i just picked up a nice older Alpine 9585 off DIYMA. I like running the older Eclipse HUs also some 5 and 8v but not as many features asnthe new units provide, but pretty simplistic to run and operate.JVC was bought out by Kenwood a coiple years back and are basicly the same units/models as Kenwoods Same Co. You can find a really good updated HU for $150 for a single din

why is having a high volt number better for the stereos? i didnt think it mattered much

Cleaner signal and less distortion

That would be a real hassle and a long run of wire. at the HU to a solid grounding point would be a bit easier I would think??Prob that PICO FUSE on that HU

not really,take a 12-14 ga wire connect it to the ground wire from the hu and just run it back to where the amp is grounded to the frame of the vehicle,not hard at all, beats the heck out chasing down hit and miss multiple ground points which could cause ground loops.

Pioneers were notorious for having bad grounds on the RCA outputs. I had the same issue so I took some speaker wire and ran a figure 8 around all the 3 sets of RCA's behind the head unit, and applied soldering to hold its shape, then I grounded the wire to one of the head unit screws on the metal and..it worked! At that moment, I was running PPI PC450 and a Rockford 800A2 so I knew the amps were good.

I never heard of this technique. I am running an old Pioneer Appradio with the whine issue which was never resolved. What I settled for was using one set of RCAs for both amps, which worked. But I now want to try this for the sake of science! I even tried ferrite rings to no avail.
