Hello first of all! So I have a problem with the basses. There is absolutely no pressure and as soon as I make a little louder the basses completely oversteer and it sounds as if they are full throttle, that’s right. The problem is with my rear speakers and with my subwoofer. I already have all possible settings on the radio and at the power levels tried but the problem is always the same. Below I list my components: Radio: Panasonic CQ-D FX572N (Mp3,CD,…) Output voltage 2.5V 6channel Front: 2 x Infinity reference 452i 105W Rear 2x Inifinity kappa 693.5i 330W to Magnat Bull Power 6000 Enstage with 600W Input voltage: 1-10V Subwoofer: Pioneer TS-W383F (Free air subwoofer with 600W, 38cm) to Magnat Bull Power 6000 Power amplifier with 600W (only 300W are connected to subwoofers because only 1 channel is connected) Power amplifier from the subwoofer is connected to the subwoofer out from the radio. The parts are all new purchased and were also nick grad bill ig, so I’m sure it won’t be the quality. I hope someone can help me here, thank you!
