what size are the toyota 4runner 1998 stock speakers front and rear?

Answer 1

The front door speakers are 7" round speakers. You can replace them with after-market 6 1/2" or 6 3/4" speakers but you may need to purchase or fabricate an adapter plate.

The rear door speakers are a 4" three-hole design. After-market 4" speakers can be used, but again, you may need to build an adapter.

Answer 2

Go to www.crutchfield.com and enter your vehicle info.
It'll then list everything that fits your car, including speaker size.

Good Luck!
