Options for stock speaker mounting in 1994 Ski Nautique

[imtsez]

Hi all,

I'm looking to upgrade the stock speakers in my 1994 Ski Nautique. I would like to keep the original mesh speaker covers in place. I've included a picture below to show what I'm talking about.

Does anyone have any recommendations for speakers to achieve this? I'm looking to keep it below $100 a speaker if at all possible.

Thanks,
