I took the interior of my door panel off today and noticed a female plug for tweeters to plug into therefore I am now considering purchasing a pair of 4 Ohm OEM Tweeters to connect parallel with the mid-range. I understand the 4 Ohm mid-range speaker in the doors are already connected in parallel with the 4 Ohm woofer under the seat. To prevent dropping the Impedance further (below 2 Ohms) I am considering replacing them with 8" Earthquakes to run off an separate amplifier.
What do you guys think??
