2010 Forester Premium
The adapter that comes with the speakers places the speaker close enough to the grill that it's not an issue IMO.Resurrecting this thread from the dead but thought it better than starting a new one.
For you folks with the db651 speakers installed - what did you do about the gap between the adapter ring and the door frame? I've only replaced the rears (dynamatted the doors while I was at it), and as I'm sure you've noticed the spacer/adapter ring doesn't mount flush.
I find that I have hardly any bass coming from the rear speakers, definitely lacking compared to the factory speakers I still have up front. Needless to say I'm a bit disappointed (the mids and highs are nice and clear though!) and just trying to sort out whether that gap is the problem, or whether something else is going on?
Oh, this is in a 2011 Foz and with the factory HU.
If you only replaced the rears, the power requirements between the stockers and the Polks is significant. The stockers will have more output at all frequencies, not just the bass. When you replace all 4, you won't have a bass loss...
