Do you have a speaker in the middle of the dash? Do any models of the Tacoma come with a speaker in the middle of the dash, like the 4Runner with JBL sound?
If so, use a factory Toyota speaker grill, and place the speaker in the dash. I did this to my 4Runner. The dash is made the same, with & without the fancy sound system. There is a section that gets cut out, for the JBL speaker. I cut out that section, mounted a small speaker, and snapped in the factory grill. It sounds great.
You could use the factory speaker too, if you can get it for a fair price.
