Installing audio system to stock headunit? ...possible?

[chrisfun8806]

Hey there guys,
I'm new to these forums as I just got a 8th gen civic about a month back (Australian, VTi) , and is now interested in getting an audio system going. Thinking about amp, sub, and speakers. I won't be getting a headunit because it looks pretty much impossible so I was just wondering -

Will the civic headunit have sufficient power to run the audio system? I was thinking about getting this amp. Alpine MRV-F345



Its specifications are Alpine MRV-F345 4-channel car amplifier 75 watts RMS x 4 at Crutchfield.com

(4/3/2 channel power amplifier. 75W RMS x 4 [4Ohms@14.4V 0.08%THD] 300W RMS x 1)
Don't know what this means lol.

Thinking of bridging 2 channels for a sub and the other 2 for the front speakers.

Any help or advice is appreciated and Sorry if I sound a bit noob and this thread is in the wrong place >_<

Thanks!
Chris

as long as your stock Headunit have an RCA preout then that amp will work with it.
