front speakers dont work
 

front speaks dont work and the back ones do, weird what can be wrong.

stock or aftermarket head unit?

aftermarket

you didn't bypass the front amp or power it up.

The wiring colors are in the FAQ for FC sticky thread at the top of this section. You may wish to read that before posting

well the thing is that they did work . until this one day i took out the speaker under the steering wheel cuz it poped then after that the front ones stop working

well when you took the speaker out, did you short the two wires together and then turn on the radio??? if so then you might have blown out the amp (either outboard or inboard depending on how your system is wired).

where is the amp in our cars...cuz i have not hooked one up yet

depends on the model, some have an amp built into the passengers speaker for the front speakers, some have it in the dash behind the dash speaker, and some have it in the radio and some have it under the radio.

Need to know the model and type of stock radio to know the location.

its a 90 gtu and didnt come with a stock raido wen i bought it

? icemark?
