I recently had a pioneer double din touch screen installed and the product seems good, but the sounds isn't even as good as the stock deck. it sounds like it's not using the sub woofer at all. Any suggestions?
By the way I had a shop "professionally"do this. they don't know what to do and I paid a lot of money. I would like to be able to enjoy my new deck

 

Check the receipt for what parts they used to install it.

That'll be a big help in determining what they did wrong.

It's possible they bypassed the factory amp and are powering only the four door speakers, or if they didn't use a PAC ROEM-NIS2 (or equivalent) then the balanced signal problem is screwing up your audio.

 

The receipt is itemized poorly. It doesn't have any model numbers on it. Not even for the deck that I bought. Im having so many problems that I would just like to get my money back. Before I brought it in, the stereo had bad reception, so he said that he put an in dash antenna in it, and it is 3X worse than it was before. I don't know how somebody that owns a shop could call me and say my car is done. Crazy... Thanks for all your help.

 

Wow, that's just jacked up.

You might have to get somebody experienced with dealing with shoddy service (parent?). Go in there with whatever receipts you have, a list of your expectations and a list of what isn't meeting them. Demand they perform the work as per what was originally agreed to, or refund the cost of labor.

 

Thanks. I ended up getting all of my money back except I had to keep the metra. They told me that they would call me when they're done and I told them that I would stay and watch. The guy doing it seemed pissed off when I said that. It was pretty funny. Thanks for the help.

 

Why not install it yourself? It's really not that difficult, and you'll learn something new.
