its kind of like square subs. they get louder because of more surface area but at the end of the day the sound quality suffers. its why you don't see high end companies throwing out 6x9 components but there are 6.5s in the thousands of dollars range.
plus compared to those rockfords i doubt there is more surface area since they don't use a tower in the middle like the 6x9s he linked.
I get little to no audible sound from my back speakers anyway, so that why I always thought I should just leave the bass to the rear speakers and let the highs come through the front haha.
When I upgrade I might just take the 6.5s out of the deck completely and double the power to the fronts. That way I can get more air coming into the cab.
I think that a DD m1 and 3500 would blow up the rear deck speakers anyway so it wouldn't matter

was my reasoning as well (although not quite as expirenced im sure)
i just read the reviews for both and they said the 69's were rich bass/good sound and the 65's had nice mids/highs
Bro just buy the 6.5s for the rear like he said. They always do have better sound and I really like the way those Powers are designed.Quote (zell1luk @ Sep 12 2012 09:40pm)
Dynamat is veeerrry expensive and is probably not worth the cost at all for what you're doing.
You could grab a pair of universal baffles for your back speakers and maybe the fronts too. I'm sure that would help with bass reproduction a little.http://www.sonicelectronix.com/cat_i452_speaker-baffles.htmlThis post was edited by dr_deranged on Sep 12 2012 08:43pm
