Hello, I’m not getting any further here. Recently I installed the above-standing LS in our Fiat 500. With aluminum butyl and insulation provided. First try was really disappointing and sounds worse than the factory tortoises. It lacks bass and depth and the HT only tremble. The Focal have 4 ohm. Unfortunately I couldn’t find out what the factory radio uconnect 5 is doing. One Fiat 500 has 4 ohm LS…the other 3ohm… Does anyone have a tip…?
