RA28 speaker boxs

[stormbird]

What size speaker fits into an un modified back seat speaker box of an RA28

[Omegaman]

i used 4 inch and 6" with spacers on the front.
I didnt cut any of the box, just the 4 screws on each.
Its a good idea to get some deadener and stick it on the inside of the car behind the speaker. it does help with sound quality.

So a 4" speaker will screw straight in no mods?

well, when i say no mods, i mean i drilled through the speaker part on the box. so all you see is the 4 screws from the outside.
