PUMPKIN CAR STEREO SUPPORT CENTER

Hey there,
I got my new pumpkin 10.1 inch radio from Amazon (order #304-2991605-1769931) yesterday and now I have a few problems with it and I hope someone can help me.
I installed the device like my old one was. It boots up and works so far, but only the 4 little speakers are working. The big ones in the doors are not working at all. I only have 8 pair of cable to connect to the device. This worked well with my old radio (aftermarket one too). But with the pumpkin not. Any idea what I can do? Second problem is the phone connection. Bluetooth is okay but sound and microphone is very quietly.
Third problem is the wifi. It takes very long to connect and the signal is very weak. The distance between my wifi router and the car is only 5 meters.
Thanks in advance for your help.

Hi, about the speakers issue, cause this unit is just an universal model which only have four couples speakers wires.
Could you please tell us what kind of your car? We will help you check if the adapter will make your big speaker will work.
About the microphone issue, could you please turn up both your phone and our unit volume to check? If you used the external mic, could you please use the internal mic to check?
About the wifi problem, could you please connect your hotspot from your smartphone to check? As you know, the wifi working have relation with the wifi signal distance and network smooth.
