This is my audio upgrade for my truck and I think I may need some advice so feel free to comment. I seem to have the amps but not quite the sound I want. This may be due to how they "tuned" my amps or maybe its the settings in my head unit 143-BT (for now), or maybe its my front door speakers (610C), or my rear door speakers (610). I don't think its my subwoofer (currently a 10-in Image Dynamics 300 W in a custom enclosure. I spent the money and I want it to sound like the amount of money I've spent. SO FAR! Let me know what you think I should do.
