I am looking to get a pair of 6.5's for my front doors and a pair of 6x9's for the rear (even though you guys don't really recommend it) and I am just looking for 2 sets of these speakers that I can just power through my HU that will still give me pretty good sound quality. I have Infinity Kappa's but no amp to power them. So, until then, I want to purchase some cheaper speakers that I can power through my HU. I was looking into JVC or Pioneer speakers just for the meantime. Anyone else recommend any good speakers that can just be hooked up through the HU and will give me good sound without an amp? (Basically wattage that the HU can support. Going to pick them up in a few days, need help. Thanks guys.
