I have a coupe with the bose system...the door speakers are going out and im dropping in some infinity 6020cs speakers and tweeters...I am planning on replacing the bose amp but i dont know if i should get a 4 channel amp or a 5 channel amp? what do you guys suggest? and brand in particular?

i did a search but didnt come up with the answers that i wanted.

 

Hey bro, im kind of in the same boat as you are but im going to change all 6 speakers. From what i read, someone told me if i wanted to do a 4 channel amp i should wire 2 of my 6.5's to 1 channel and the other 2 6.5's to another channel and wire each 6x9 to the other 2 channels and turn up the frequency a little on the channels that you power the 6.5's. but then again a lot of people said not to do it so i dont know. im thinking of getting some high end 6x9 and getting a seperate 2 channel amp to power it. Good luck with everything bro. let me know how it goes as im also trying to do a complete system changeover on my G in about a week or two, still doing some research.

 

depends on what you want

5 chan amp means, front speakers(left right), rear speakers(left right), and a sub

4 chan = front (left right) rear (left right)

Name brand and build of amp means more than wattage of amp

in other words get a decent name brand amp that does ~100rms vs a cheap brand that does ~150rms

 

but dont we have six speakers? also will they all be wired at 2ohms?

 

yes you have 6 but the front two are powered via a single crossover

you run a single wire from the amp "left" to the left crossover
from the crossover you run a wire to the tweeter and a separate wire to the mid

a crossover basically "Y"s off from the amp



thats kinda hard to see but the furthest left is from your amp

the rest of the output go to their speakers

 

better example

this example is of a basic woofer and tweeter set up (2 way)

the first picsture I posted was a 3 way set up
