Yesterday I with my friends built this system into the car.
Amplifier: Mac Fearless 1000 2200w
Powercap: hpc1000el 1.0 farad
Radio: Pioneer DEH-4500BT
Everything went wonderfully, but when we wanted to really turn it up we noticed on the one hand that everything didn't sound clean because we hadn't made any settings, neither on the amplifier nor on the radio, and on the other hand that the bass was suddenly gone. The radio can be turned up to volume 60 and that happened at just 40. Before I install a new high-quality fuse I want to ask what kind of ideas you have.
Best regards!
