I used Kicker for Amp and Kicker for door and bulkhead speakers
all were a great fit but it needed time because I removed all the existing, all wires too, and replaced with new
The rear subs are now also front facing (crazy huge difference)
Much better sound as front facing.
If there was more room in the roadster I would have like to add a few more speakers but
no room and this year only 2,000 miles driven. It’s now back in the garage ready for winter
I bought a Mini Coupe as a daily driver. That little car came equipped with 10 speakers. Crazy amazing sound for a factory setup
