Your speakers need crossovers. It's not the job if the head unit to route the appropriate audio signals to each speaker. The OEM amp had built in crossovers.

Bs. Crossovers are designed only to separate out the tweeter and midrange/midbass signals. You should never pass subwoofer signals to your main speakers and you should not pass frequencies above that range to your subwoofer. Doing so causes distortion and a general lack of fidelity.

Hi ac_2007, hope you can understand there's time difference between us, but I'll respond you guys as soon as I can. No worry we'll try our best to help you. Actually I've asked our tech yesterday, they're just checking your issues mentioned carefully but need to take some time. Please kindly wait for a while with patience.

For the issues mentioned:
1) For your speaker issue, our tech confirmed it has nothing to do with our unit and the high-pass filter. Pls check if it's the problem of your speaker itself. About your friend's screen issue, they're checking, I will update you if there's any advice from our tech.
2) You can add an anti-glare film on the unit screen to prevent screen-glare.
3) I will PM you the software to fix the launch.exe error later.
4) The USB/SD interface is designed in this way, hope you can understand.

Sure we will take good care of your case, it's well known that we have steady customer support and 2 year warranty, will give you a proper solution finally, thanks!
