I have a 2023 Toyota GR Corolla. Terrible factory sound system. I put in new rear speakers and a small amp behind the head unit to no avail.
Never been to HD Audio, but the reviews were good. Erick and Seth are nice, friendly. They had not worked on the GR, but I was willing to let them take a stab at my car with a larger amp and a digital processor to split the signal to the rears better. Put down $100.
Parts came in, and problems started. Turns out the GR Corolla channels everything thru it's amp (under pass. front seat) including auto functions. At some point they got all sorts of dash warnings and my power steering went out. They brought in an auto electrician, he could not find the problem.
At this point Erick suggested I'd have to take the car to the dealership to correct the problem. And since I had aftermarket work done, the question was if they (I) had voided the warranty. So I took it in and didn't tell them the whole truth. I felt uncomfortable lying, but I also didn't want to get soaked for some huge electrical problem cost.
Turns out they had to disconnect all the LIN modules (local network) from the CAN line (controller network) to reboot everything. Pain in the..., but nothing fried. Just $450 labor (which was surprisingly much lower than I anticipated).
So now, everything is back almost, now, I have no control over the rear speakers, and HD Audio still does not know what they did to put things on the fritz, or how to proceed. So at this point I decided I didn't want the car to get zapped again, and I would live with the crappy audio.
As for the $100 down payment, and the $450 out of pocket to the dealer... of which I didn't do anything wrong... nothing from HD Audio. Talked to Seth, he copied the bill, said he would pass it onto Erick. Called Erick 2x, no response.
So I'm not upset that the guys couldn't upgrade my audio, no even upset that they glitched the car, but come on guys, write it up as a loss and help me out with the bill. YOU guys were the ones who fritzed it. I know it was unintentional, but to stick me with the bill and then ghost me? That's b.s. Erick.
Not good business. So here you go, bad review, and continued bad word of mouth. Mike O' read more
