More than a year ago, I installed MINI’s high end factory stereo DPSM system in GPMINI – it sounded very good but lacked the punch of good subwoofers (which I subsequently solved!)
A few weeks back, I noticed a slight background noise from the speakers, when music was silent – it sounded a little like the clicks & burbles of failing electronics.
This past week when I drove GPMINI again, my heart nearly stopped when the speakers suddenly started “exploding”, cracking with such a loud force that I felt the breeze on my legs! A scary deafening thudding noise!
I was pretty sure that the DPSM amplifier had failed – but to confirm it, I removed the Alpine head unit and temporarily re-connected the original … after a couple of minutes, the same explosive noises occurred (apparently the amp fails as it warms up).
With Josh’s help, I was able to confirm that the amp turns it’s “error” light on every time the speakers crack – it’s as if it realizes it just failed, and shuts itself down for a few seconds.
I bought the DPSM kit from MINI of Peabody and called them – it turns out happily that the kit has a two year warranty, so once I took the car in for them to confirm my diagnosis, they were able to order and install a replacement amplifier.
This morning I headed down and got the keys, then spent half an hour re-installing my Alpine head unit and putting the dash back together (including re-installing the glove box) … then a nice 100 mile drive to check that everything is once again working perfectly, which it is 🙂
Many thanks, Scott and everyone at MINI of Peabody, for getting my car back together so quickly!

ARE YOU SURE YOU’RE NOT WILL FROM UNIQUE AUTO?
There must be some thump’n and a bump’n going on inside that MINI!
Bump’n on Sunset would be a good tune for you in that car. It’s by Wes Montgomery.
I’ve had the same thing for a while now. thought it was a loose wire but haven’t gotten around to looking into it. Guess now I know what the issue is. Now to see how to get a replacement amp.
