I purchased these speakers after reading great reviews on SE. I installed these in my impala powered by a 2ch Eclipse amp(70RMSx2 @ 4ohms) and I, nor anyone else who I let hear these can come to realization that I only have one set of 6x9's! These speakers sound beyond incredible for the price! I wish I had room for more because I would order another set ASAP!! The BASS,MIDS, and HIGHS that these speakers produce is simply JAW DROPPING!! Everytime I start my car and turn the radio on I SMILE so hard because I still cant believe it!! You will not regret buying these ALPINE 6x9's!! Thanks Sonic Electronix, you are my HERO!
