Confirm Info 2012 EX Upgrade

[Ranger SVO]

I've done a bit of research, and I decided that I may want to upgrade my 2012 Civic EX sound system. Factory radio will be retained

From the reading that I've done, it seems that a majority of the problem is the factory Amp. I am considering replacing that amp with an Alpine MRV-V500 5-Channel Amplifier.

So this is what I've read so far.
1. The factory radio outputs a low level signal to the amp. In other words, I can simply solder on RCAs and plug into the amp

2. Unlike my 2013 Sonata, the 2012 Civic EX radio does not need a signal processor because the signal to the amp is reasonably flat.

Can this information be confirmed?

I don't have the hook up answers...... But it's more to it than amp's...... 1st the speakers have small magnets, so if you want better sound, you'll need amp & speakers that match each other in performance............ 2nd I've heard the rear speakers only have a small fitting cavity, so you're going to need more fitment info before you buy anything(IMHO).........
