Out of phase means you have the speaker wires crossed.   (-)'s are connected to (+)'s
Do it right the first time

So I tried inversing the polarity on the left door speaker and I didn't really notice any difference. After a little bit of listenning I noticed it's really note the amount of bass that is to low, its the quality of the bass. You see when I set the volume / bass higher the bass starts to sound ugly; I get a vibration in the bass sound, and not the clean heavy backfround sound it should have.
Could it be that the door speakers are not properly fixed / isolated ? I had them built in by a auto mechanic so I guess he should have done his job well ?
Or is this a HU problem and something thaht would be fixed with an amp ?
thanks
Paul

Honestly even when those speakers are performing at their best..they wont be very good. I'm not a big fan of pioneer either. I would suggest atleats getting rid of the Sony's. Yes they are generally considered a bad speaker. Heres a list that might be helpful to you or anyone else brand new to the car audio world. Its from another forum that I am on.
This is the infamous Good, Bad, and Ugly list.
These are some pretty generalized groupings and also very subjective. We've simply based our experiences with the products whether they are direct installs, personal property or extensive research. You should always physically listen to a product before purchase because you are the one who will determine whether or not an item "sounds good" or not.
This topic, while being controversial, is simply a generalized guide meant for beginners in the hobby. Many brands specialize in certain items, ie. better amplifiers than speakers, better mids than subs, etc... Also almost all manufacturers offer entry level products as well as high quality lines. As I stated before, this is a GENERALIZED guide. It is your responsiblity to research and audition every brand before you purchase anything. Good luck with your decisions.

Paul, get yourself a small 2 channel amp, even a pre owned one and some good front speakers. You will have a grin for a whole week  when you hear the difference.

Okay seems like I'm gonna go for the 2 maybe 4 channel amp solution. My question is, is it possible to have some decent bass with only a small amp (30W RMS) and some small speakers (I can only fit 17cm in my doors) ?
Thanks
