Anyone know what size speakers are the 2009 base 370? I want to replace the dash and door and also install some in the false speaker set ups behind each seat.

m&m

In my 370 2014 the door speaker specs are 6.5 in. with 3 in. depth. Not sure about the '09 and not sure about the rear speakers but I'm assuming they're at least 6.5 also.

I found these 3-ways on Amazon for dirt cheap and will push them with an alpine 445u.

The pioneer 6.5 RMS is 50 watts. Any decent head unit will push them but the alpine 445u will push 45watts RMS by 4 channels so those inexpensive 6.5 pioneers should sound very good with that power.

However, the alpine 445u is only plug and play if your head unit has at least a 15amp fuse. Other wise you have to route it's power wire through the fire wall to the battery with an inline 15amp fuse.

I think the dash speakers are only tweeters so you wouldn't even need them with a 3-way speaker. You can just leave them and then add rear speakers if you only have the 4 channels on your head unit.
