ok Yes I used Search... I found one that cnotch it with a sawzall.. Does any one have any pictures. Im think of drilling 2 side by side 2inch holes with holesaw bits.. Just want boat a little silent thinder louder.

no I ment the slient Thunder Box ... Thanks for the Audio Refresh 101.. Been over 10 years since I had a system LOL

Original SR1 Silent Thunder or Fastech box?

Not sure about Fastech, but Sawzall is the way to go. Depending on which boat you have, you'll see it's not that easy to reach the baffles with a hole saw. I think I used an extra long blade on the Sawzall. I also had the luxury of removing the tips.

I removed the tips and used a dremel it won`t take long.

agree remove tips, I used a long wood bit for holes followed by sawzall with long blade
