I wouldn’t waste money on two sets of 6.5 ..get one decent component set some components come with biampable passive crossovers so you can hook front and rear chs of your radio to the front speakersAt or under $100. I'm ordering new in a day or 2, just decided why not post here? I didn't want to buy used but I think everyone here would be trustable.
I'm running these through the HU until I can afford an amp.
