i noticed after i got my components puut in, that when i drive over bumps my door rattles, and when i close them too, sigh... this car audio shop is really pissin me off! they did a crappy job and i paid them $280 for this [censored]... they took 5 hours to hook up my amp and components and i get back this horrible install... my amp and speaker wires werent even pronged at the end, they were just cut and you can see the strands of copper or whatever, and they connected to my amps just like that, wtf? they didnt even run the LOC from my headunit, they didnt take out my console to do that part right, instead they ran 2 seperate 2 channel locs in my trunk... i thought the cleanest signal was right behind the factory radio? sigh, im really mad, to top it off the wiring all messedup, not sure if they grounded one of my amps right, but my amp keeps reporting RCA floated ground, sigh.... im so damn angry&!!@*(!

 

I'd take your car back ASAP and get a manager to look at the mess. If my speakers were rattling I'd be furious with someone.
If things are moving around back there you may end up with a short-circuit, or damaged speakers.
Go back & yell at someone until they fix it!
