Answers:

Is a car automatically totaled out from a head on collision?

did you install it yourself? make sure you didn't wire everything as constantly powered and to only power when the radio is active.

Unexpected car spin out never has happened before. any idea what went wrong here? thanks?


did you run the stereo system without the car running? that will drain your battery fast.

1999 Honda Civic, has original spark plugs in it, good or bad and should I have them replaced, and why?


the problem is probably not the alternator, that just charges the battery. to save your battery, you should probably install a capacitor to supplement the subs and less drain on your battery.

How do I bring back the color on my cadillac's vinyl top?

id check and make sure your amp isnt still on when you shut off your car. if there is a light or something on your amp so you can tell. i had to have my factory amp replaced in my car by the dealer ship and i would park my car for the night go to start it in the mornings and it would be dead. it did this for like 1 wk then i took it back to the dealer ship and they had one of the wires wrong i think maybe the remote wire but im not sure so you might need to check and make sure your amp goes off when your radio goes off.
