New Speakers to Replace Furrion

[saltyturtle]

Does anyone have a recommendation for higher quality speakers that will fit in the hole that the Furrion DV3200 speakers are in? The opening is approximately 8" x 4 1/2". The Furrion speakers are pretty poor. They came in my 2017 Alpine 3401RS. I haven't had any luck finding better ones that will fit. Thanks.
