I'm looking at replacing the door speakers in my 2002 blazer. It also has 4x6 in the dash , which the good people at crutchfield recommended I just leave. The doors have 6.5s them. I will be running an old verge 4x46 watt amp and an older rockford for the sub. The head unit is an old jvc cassette/cd changer unit. Any suggestions on decent door speakers? I was recommended polk db651s. I love my ht setup with polk monitors,just am not sure about polk car speakers.Looking to stay around 75-120$ per pair , but will go a little higher.Thanks in advance.
