No that would be a 2 channel amp. 1 speaker per channel. 2 speakers= 2 channels 4 speakers= 4 channels
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.
A mono amp will not sound good with door speakers. There are to be used with subwoofers
Monoblock amp? No. Only 1 channel which is good for one speaker, or one sub. What you need is either a 2 channel amp or a bridgeable 4 channel amp, which would be overkill anyway. If the amp you have is 2 channel, it would be ideal.
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.
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.
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.
Use 1 channel for fronts & the other channel for the rears.
200 RMS 4 channel or 2 channel so u know add the rms of the speakers to find the amp rms needed
No. The radio or amp would be fused, but not the speakers.
Yup
there are amps behind the door speakers
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.
