I was quite impressed with the sound from my Octavia initially and for a standard car audio system it's not bad. However, it's summer time and time to crank it up. 

I read on a previous forum that replacing the door tweeter 6.2uF Capacitors with 2.2uF dramatically improved the top-end sound and eliminated a lot of sound distortion. I'm planning on doing this and putting dynamat insulation behind the door speakers. I've seen the YouTube videos on door card removal and it looks pretty simple. 

However, I'm also wanting to upgrade the Door Speakers Front and Rear. So I need some info:

 

The existing speakers are simple 2 way. I could go for 3 or even 4 way but with the car having component speakers (separate tweeters at the top of the doors) I figure it will be best to stick with 2 way (Decent Brand, RMS Power, Frequency Range, Appropriate Size and Impedance).

 

Also, I was considering buying component speakers and completely renewing the tweeters as well (I would prefer to do this supposed to simply changing the capacitors on the existing tweeters in order to ensure frequency matching with aftermarket door speaker). However, I read somewhere that the standard tweeters are glued in place and are not to be removed. 

 

Plus there are other considerations:

 

What physical size are the standard speakers? 

Regards the Amundsen Audio Output :

What is the rms power output?

What is the impedance? 

What is the frequency range?

 

Any help or advice would be most appreciated.

6.5" standard. The power can only be 14W RMS or so, and it's more than likely into 4 Ohms. I'm not a fan of messing with the caps. In fact, let's go do some math.... *if* the tweeter has 8 ohm impedance and the woofer 4, then swapping 6.6 for 2.2 will increase the frequency of the  HPF to around 9kHz, from 3500. That's more than strange and I don't see how it can affect distortion in a measureable manner. Yeah, OK, if the caps are better quality, maybe, but I don't see the point.

 

Use the provided crossovers with the speakers you buy. Eton do something approaching a plug and play set, Helix will too. I've heard good things about both ESX and Emphaser recently, too, but I don't know what I'm going to put in. I suspect it might be something more exotic (more than likely the ER18RNXs I have lying around if I can get them to fit nicely).

 

Threads you might like. 

and then there's Marko's thread over on TalkStuff which has a lot more detail. 

 

Personally, I think I'm up now for a complete DSP setup, misusing a Pi for source via a HifiBerry DAC and a MiniDSP C-DSP 6x8...
