Polk Audio DB57
Just bought two pairs off of Craigslist.
Installed two in the front doors no Problem.
But when i went to put them in the rear panels, they were too deep.
It's really no big deal because i have Two Kicker KS69's in boxes behind my seats anyways.
But the speakers sound REALLY good so far. I haven't got to turn them too loud yet because im breaking them in. They sound better than my 6 1/2" Infiniti Reference componets i had in there before.
But soon enough i will have the extra pair on here for sale.
Let me know if your interested.
