Infinity stereo problem

[99GSTszeikus]

Well last weekend i decided to change out my blow speakers in the back. I got some speakers from best buy, after i installed them there is no sound coming out of any of the speakers. I mean the head unit turns on and it shows radio stations and i can change the tracks on the cd's but there just isn't any sound that is coming out. I have no clue what it could be or how to fix it. Any help would be greatly appreciated, and yes i have tried to search but i didn't find anything like this.

Do you have the amp under the passenger seat? Are the speakers fed from it?

 

[99GSTszeikus]

yes i do have the amp under the seat, and the speaker wires fed to it.

And do you have the DIN cable feeding the amp from the radio head?

 

[99GSTszeikus]

what exactly is a DIN cable?

 

[sjgYFZ200]

Its the cable that goes from the head unit to the amp. Gives power and sound to the amp

 

[99GSTszeikus]

yes the cable is hooked up

Did you wire the rear speakers off the amp, or off the head unit?

 

[FireyIce01]

did the cable possibly come loose from the head unit or the amp? you made sure that the + went to the + and - to - on the speakers? is there some sort of mute on the head? does the amp have a good power and ground (is it powering up?)?

Those are the only things I can think of that would cause problems.... I'd take a multimeter and make sure there's power goign to the amp, and then make sure there's power coming out the speaker leads...

I wired the rear speakers right off of the original wires, i didn't mess with anything on the head unit or the amp. I guess the question i have is would getting an aftermarket headunit solve my problem, i honestly spend about 3 to 4 hours a day in my car commuting from home to school to work and back home i can't stand not being without music anymore.
