I have been installing car audio systems since the early 90's. I ordered these speakers simply because they met the exact specs I needed for a Dodge Challenger sound system upgrade. Dodge sedans (from the factory amp cross-over settings) have mid-bass only in the 6x9 door speakers and they are also 2ohm OEM speakers. I needed a set of mid-bass 6x9 2ohm speaker's and these were the only ones that met that spec. So I took a chance and ordered them. I am nothing but very well pleased with them. They are plenty loud enough, and the bass is very tight....no vibration, no distortion even at almost peak volume levels. If you are in need a=of good woofer\mid-range bass 6 x 9 speakers....you can't go wrong with these!
