um im tring to remember what sizes are in the blazers i have an 03 im not sure but isnt it
4 1/2"s in the dash and 5 1/4"s in the doors the rears im not sur eif im going to do because of the sub will kinda drown them out so a waste of money

am i right on those sizes?

 

ok, in the dash you have 4x6's and in the doors you have 6.5's. no way man, hook a seperate amp up to run your door and dash speakers, trust me, they won't drown them out [:

 

ya ive been looking for another amp for the coaxles but money si tight and im going a little by little lol this stuff was alot cheaper when i worked at an audio store haha

i looked on ebay for some amps prices way to low for my likeing i mean like scary low lol so to the audio shops i go

any suggestions for the 6 speakers? and the seperate amps for doors and dash is out boss lady will not go for that lol so i was thinking about the pr 100.4 its 70x4 at 2 ohms 50x4 at 4 ohms
this that should be ok for the dash and doors

 

well, i went with kicker ds650 for my door speakers, and kenwood 4x6's. they sound perfect to me, but i have a high pass crossover on all my door speakers an my tweeters so the only bass i hear is coming from my subs.

 

I am no audio pro BUUUUTTTTT I have a 05 Blazer and I have 1inch tweeters in the dash in a 4x6 plate (i Believe) I have a 2 channel amp running my 2 12inch and a 4 channel amp running my doors and rears my tweeters in the dash are being run off the deck and is plenty loud that the subs don't drown out anything. Again by no means am I any expert, just letting you know what I have.
