Hello to all! I'm a newb here as well and I'm planning to install the db675s in the front and MMC690 in the rear of my Camry. Can I get away with this? Or does the dB series have a different "voice" compared to the MMC Momo series speakers? Too bad Polk doesn't make a MMC6750 component set. Is there going to be a db6751 available soon? Also has anybody heard the difference between db675 and db6750 sound quality? Any recommendations? Hope to hear from you all!
