I want to purchase a car stereo online but need to know if the stereo is compatible with my car. Is there a website that I can go to, to find out this information? Thank you in advance.

I have two-1000watt amps, two-15 inch subwoofers and a multi-input equalizer that I'd like to keep for my home stereo system. How would I go about wiring all the components to work off of a AC input or how would I get a DC input working at home without it having to be a car battery? The wiring for a typical car installation I'm familiar with but how would I wire this for power without the car or the battery's current?

Hi all, thanks for reading my question! I have a subwoofer and amplifier from my older car and would like to install them for my new car (Toyota Highlander). The CD stereo is the original stock, and I have already taken it out of the dashboard and checked what optional outputs it has on the back. It actually did not have a subwoofer output. When I asked car audio staff at Best Buy, he said that we can use a splitter (I am not sure if it is correct) and get the cable hooked up from the speakers on the door. I know if I take my car to car audio shops, I can get it done fast. But I dnt want to leave my car for a few days because I need to drive it everyday. Have someone done this before ? Is there any website that instruct the installation or sell the splitter I have mentioned before ? Thank you, all!

I have Pioneer DUH-p4000ub car stereo and a couple of times, when I started the car, the radio was just dead. I brought it into the dealer, the fuses and power in the car were alright, but when they reset the radio by removing it, the stereo worked again. I imagine it's going into safety mode? Can this be because I'm using my car's (protege 2002) original speakers and that they are measuring 4.4 ohms instead of 4? Please help! Thanks!
