I'm usually a home theater audio person, but was hoping to get a bit of clarification regarding some Polk car audio. Up until recently I was running the db691 6x 9 speakers and corresponding 4 x 6 speakers in my car using a pioneer 5100 receiver. That car is no longer functional, and I now have a new one. I still have the 6 x 9s and the receiver, and am looking to get a pair of 6.5s for the front of the new car. Would it be worth upgrading to the mm6501s? Or, would there be a huge sound quality difference that would throw the balance way off. I'd love to go mm all around, but after buying the new car my money situation isn't what I'd like. Would it be it a good idea to go with the mm series now and then upgrade the 6 x9s later to the mm series? I will say I was pretty happy with the db series while I had it, but then again I was happy with a home theater in a box at one time also until I heard better. Still no sub plans for the car, but knowing what my sub does to the home system, I'm strongly considering getting something like an 8 or 10 inch powered bazooka tube (for easy removal when tossing the random kayaking junk in the trunk).
Any information you have would be greatly appreciated. I'm just way out of my league as far as car audio goes.
