Mustang Speakers 87-93

[98 Camaro]

Hey All,

I'm doing some interior modifications this winter.

I was thinking about upgrading my stock speakers in my 91 Fox.

Fronts = 3.5"
Rear = 6" x 8"

I have no idea what is good or bad.

I'm budget minded, but don't want to buy junk.

Any opinion on what brands to stay away from or focus on.

Thanks!
