2013 civic si hfp w/navi audio upgrade.

[KCGamble]

So I know almost 0 when it comes to the audio system in my vehicle. What I do know is that bass is so weak I would to upgrade something. I'm just not sure what exactly. If I upgrade the sub will I need new speakers and amp? Suggestions for audio upgrade in my vehicle?

Others can help you more but I'd follow the info discussed here -

You can also review my thread too. Yes, you need to replace the factory amp, replace the speakers, and replace the sub with one in a box in the trunk (or custom built box on the side of the trunk if you value trunk space). The free-air sub in the Civic, as you experienced, does absolutely nothing.

If I wanted to replace the door speakers and maybe rears with some Alpine Type S, would I still need to replace the amp?

If u go as far as replacing speakers, then definitely replace the amp

Damn, I hate these speakers and would love to just pop in some new ones, not make a whole project out of it.

 

[13blacksedan]

I doubt just speakers will make a difference

 

[13blacksedan]

I would wire up a sub, and if you don't think it is good enough, then replace everything...

Replacing the speakers won't provide better sound because the factory amp is what destroys the sound quality because of the awful built-in crossover equalization for all the channels. Honda takes the crown for having dogshit stereo systems. The premium sound is actually worse than the standard stereo because of the factory amp.
