I want to rectifie something of my previous explanation , and why i changed to 1,5 Uf . The reason is , i have a 3-way speaker system with 3 woofers , and this already offers more Mid & bass , than a UNI speaker . In the explanation i recieved, they advise to lower the Uf capacity , if you have a more classic rock of power bass speakers system . So if you have a modern classic 3 way speaker systems of 1000 to 2500 euro , with a strong mid & bass , a 1,5 Uf Capacitor will balance better sound .
As i said , it 's only an advice , people are free to experience whatever they like and want.
If you have a Single-Speaker-unit loudspeaker , than a hihger Uf gives more body and bass , and is enriching the sound.
And i forgot to say , i changed also the Fuses , to Supreme Gold Silver Fuses . This give also again of 3%-5% more , but is less clear to hear on a 3way speakers kit. But it is direct more clear on a 1speaker unit .
