Use 1 channel for fronts & the other channel for the rears.
According to http://www.installdr.com/Harnesses/GM-Wiring.pdf the connector for the rear speakers is separate from the front speakers. If the connector for the rear speakers is loose or disconnected, the rear speakers would not work while the front ones will. The amp in the head unit (dashboard radio) powers the front door speakers. The rear door speakers and roof (pillar) speakers in the rear are powered by a second amp under the drivers seat. Either this amp is bad or is not hooked up.
This depends on your amplifier's specifications. i would recommend looking in the amplifier's service manual to avoid disapointment or damage to your amplifier or speakers.
It could be a combination of wires and the amp, but I would start with the amp.
You can connect a sub and speakers to one amp, depending on how many channels your amp has. A 4 channel amp will be able to run one (or two) subs using two channels (one bridged* sub or two subs) and two speakers running one channel each. A 2 channel amp will run 2 speakers or one bridged sub. A 6 channel amp will run one bridged sub (or two subs), 2 front speakers and 2 rear speakers. In my opinion, you will get the most performance, depending on which amps you use, by using a monoblock amp for your sub and an amp with enough channels to run all of your speakers. # Bridged = putting together the power of two channels to run one sub or speaker. Note: not all amps are bridgeable.
No that would be a 2 channel amp. 1 speaker per channel. 2 speakers= 2 channels 4 speakers= 4 channels
Run your power, ground, and remote wires. Then connect your RCAs to the back of your CD player and your amp, then connect your speakers to the amp..-ShockerI don't think the factory stereo has rca plugs in the back. You can run wires off the rear speaker wires of the stereo and wire those to rca plugs which you hook to the amp. Then you will have the rears running to the amp (for sub install). If you planned on using a 4-channel amp for all of your speakers, you could run rca's from the front channel wires and from the rear channel wires. Since they're going to an amp it won't effect the ohm rating going to the stereo.I had to do this in my Fiero when I had an older CD-player that didn't have RCA plugs. A new stereo with sub outs and front and rear outs created much better sound.
All speakers will work with a typical four channel amp, though you may want to check the wattage before you pair it with some speakers.
depends on the wiring check out Subwoofer Wiring Diagrams
a channel refers to the speakers or subs. for example a 2 channel amp can power 2 subs or speakers. a 4 channel will power 4.
dont know -------------------------------- EDIT: 2 Channel if really what its sounds like, 2 channels which means you have a Left + Right basically. 4 Channels is for 4 channels which like in a car would be Front Left + Right and Rear Left + Right. Reminder!!! Check RMS NOT max Power!!! -TheRamMan-
A two channel amp, in simple terms, means that it amplifies two different inputs channels (left and right usually, or could be front/rear), and outputs them into two different channels. Other types of amps you may run across is a one channel amp, which again amplifies one signal or channel.
A 4 channel will work for your door speakers. But the idea setup would be a 5 channel 4 for your doors. Then have 1 channel for a sub.
