Hello,
Previously i changed my speakers to Alpine ones and got little bit better sound to my car. Still i was not very happy. Today i went and bought Match PP 41DSP plug & play amplifier.

Amplifier is marketed to be plug & play. I bought Toyota version and it came with Toyota wiring harness. Amplifier get everything it needs from the wiring harness, separate power cable is not needed (at least 20A fuse to standard car audio system is required).
Match PP 41DSP is quite small
On the back side is different Toyota version list. Each number is different configuration on the DSP what can be changed with two buttons.
Let the tear down begin, i had some help from Toyota-Tech.
Audio unit was held with four 10mm screws.
Match wiring harness goes between these two connectors and stock audio unit.
There was perfect slot behind the glove box. top of air filter for Match. With little soft padding i was able to secure it to the place without fear of rattling noise or it moving around.
With these pros and cons its good to note that i have changed my stock Speakers to Alpine SXE-17CS 6.5 kits previously and DSP program is done for stock Speakers. I found some installation notes from some BMW install saying that you can easily change stock ones to little better with this one without fear that DSP is then way off.
I could image that stock Speakers could benefit this maybe more than these Alpines.
Pros:
+ much clearer stereo "feel"
+ sound is more level from whole range from low to high
+ deeper low end
+ super easy plug & play install
+ rear Speakers sounds better
Cons:
- DSP levels cannot be programmed, you need to buy PP 62DPS for that
- stock Audio unit seems to cut bass low when volume is tuned way up, DSP wont compensate that
- 4 x 35W 4ohm RMS is not gonne blow your mind
