No problem, hope it helps. I forgot to mention the use of a crossover in the front to add the sqwaukers in if all the speakers get upgraded. Also, the screen does come with an pretty decent equalizer setting menu with all the frequency gauges, you can set the time alignment for all the speakers. Almost like having a DSP. I aimed for a target curve on the equalizer and my next small project is tuning in the time alignment in. Good luck!2nd Gen, thanks for all the information that you've posted for me. I have a query in with the AliExpress seller about the impedence of the stereo and what not. Have to see if I have the time and energy to put this together. Again, thanks a lot for the information!
