So I recently got 2 8" kicker subs and an amp for FREE! So Im planning on making a box in my trunk. However Ive run into a few problems. The 2 subs are different ohms. one is 2 ohm the other is 4 ohm. Is there any way to wire these to an amp to make them work together. If not which of the 2 subs is better and will an 8" sub be enough to make all this worth it. Also, my head unit only has 4 channels and they are already occupied by the speakers. My plan right now is to split the rear channels before the amps like a drew in the picture below. Ok and please don't say to sell the stuff and buy something better because my dads friend gave them to me for free and it would be rude of me to sell his stuff to buy something else. Thanks!
