Default Re: Help with boom box modification

I personally do not think that you can modify this way you are talking about

I personally think you can modify it by putting a DTDP switch but the external speakers need to be the same ohm value and the same configuration that they are in now because you might fry the amp board doing what you have in mind

These are my thoughts on what you have in mind now what you have in mind might work but for how long is the real question

I have seen some of these amplifier boards just stop working for no reason at all I have on seen a few that will just keep working no matter what you do with them and I have had both experience with them

Now if you want more running time then put in higher capacity battery pack and good quality batteries this would be an upgrade that I would do have done in the past I have a small boom box that I did this too and runs almost three times longer than the battery that was in it
9 PC LCD Monitor
6 LCD Flat Screen TV
30 Desk Top Switching Power Supply
10 Battery Charger Switching Power Supply for Power Tool
