speakers. I need 2 sets of 5x7/6x8s for my Mercury Mountaineer. Trying not to spend a million $$$, but i want it to sound good. I do not plan on amping them, but you never know. These are some of the options i have been looking into, please give some input Alpine Type-R Boston S85 MB Quart DCD 157s Memphis M-Class Polk MOMOs Or should i just get some regular Polk DBs or some Alpine Type-S and get some other junk. Any opinons wanted. I do not plan on competing at all. I already have a OEM 8" sub, that i might replace with aftermarket. I was also thinking of goin Type-R in front & Type S in the rear or etc.
