Three speakers don't work in a 2004 Honda Accord what can it be from?

I have a 2004 Honda Accord and I have put a Pioneer FH-X700BT cd receiver in the car and recently I have noticed 3 of my speakers have gone dead all at the same time. I thought it was from the cd receiver so I bought a updated version and it turns out it wasn't that because I attached the receiver the the car and still the 3 speakers don't work. It is kinda strange that all 3 speakers don't work at the same time. Does anyone know why this happened and how we can fix it? It doesn't seem like it is the speakers because they never had a static sound to it or anything before stopping all together.

My 2005 honda accord hybrid trunk does not open?

My trunk of my 2005 Honda Accord Hybrid does not open. I tried the key, and the latch inside. It does not work. But I still hear the noise as if it would open. I tried having someone pull it open while I pulled the latch, that didn't work, did the same with the key. There's no way I can get in through the back seat to get to an " emergency latch".
How can I get my trunk open?

Does the Bluetooth music adapter work on the Honda Accord 2003?

I got a music adapter for my Honda Accord cause my car doesn't have an aux. Cable. This adapter is suppose to just get plugged in to the power outlet of your car or ( cigarette lighter thing ) and work no installing anything… When I plugged the adapter in it sinker perfectly with my phone but I couldn't switch my car radio to aux. The CD/Aux button was unresponsive. Every time I clicked it nothing happened… I put a CD in the car and it played it… Seems like it's just my aux that doesn't work.

2013 Honda Accord Coupe EX-L gas tank won't fill all the way?

Last time I got gas I was nearly on empty and when I ll filled up the pump clicked off at about 3/4 full. Weird. Went to a different gas station today, again on empty, and I was only able to pump 3 gallons! Anyone else have this issue? Should I take it to the dealer?
