Also should I use loudness setting?

also could a bad amp earth cause this low loudness? for example if it is only just enough earth for the amp to recognize it as being safe to power up but isnt a very strong connection?

also my car is a hatchback so it has no boot its just open to the roof, usually in a boot the sound echoes which makes it sound louder and better in my opinion...???

also my lpf is set to 80hz in subwoofer settings then my hpf for speakers are set to 100hz, does this mean 81-99hz will be missing?

Not likely, but if you're questioning your ground, just change it. It's usually way louder in a hatchback.

Yes, to a degree.

Just take it to a shop or have a friend who knows what they're doing take a look and tweak it.
