go ask a mechanic idiot
It could be a 2 channel stereo amplifier.
A mono amplifier. You need two for stereo.
Yes you can bridge this amplifier to a 2 channel at 4 ohm per channel for 200 watts out of each channel.
To bridge a Carver GA-250 power amplifier, connect the positive terminal of the output from one channel (e.g., the left channel) to the positive terminal of your speaker. Then, connect the negative terminal of the output from the other channel (e.g., the right channel) directly to the speaker's negative terminal. Ensure the amplifier is set to "bridge" mode, if applicable, and check the speaker's impedance to ensure it matches the amplifier's bridged output specifications. Always consult the amplifier's manual for specific instructions and safety precautions.

For the most part yes. However an injector (assuming I know what you are reffering to) is typically used to insert a signal into an existing coax feed (EXAMPLE: when your VCR plays a movie on channel 3 when you can still watch channel 6). While an amplifier simply increases the power of a signal. Good Luck.
The Kicker 4-channel Car amp has the Kicker logo on it.
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.
Connecting speaker leads to both right outputs, A&B, will only play the right channel of the sound (in mono) when both pairs of speakers, A and B are turned on. This won't damage the amplifier or speakers, but you won't be listening in stereo.
90 watts X 4 channel output
Your 4 channel amplifier has neither a 4 ohms nor a 8 ohms output impedance. The output impedance will be smaller than 0.5 ohms. In audio we only use amplifier and loudpeaker bridging. Don't believe the myth of matching. Scroll down to related links and look at "Impedance bridging - Wikipedia".
One can purchase a 4 channel amplifier from any local music supply store as well as some local department stores. One can also purchase these from online retailers such as Amazon.
