I hooked up a system in my truck had it for a year everything working fine.i listen to music really loud anyways i have my wires hiddin under my back seat well when someone layed the seat down it cut my rca wires in have so i find the problem replaced them with new ones and but in a new amp with bass nob but everytime i have the cd player at 0 and i turn the bass nob all the way up it starts making a thumping sound and everytime i shut off the truck it makes a thump why is it doing this ?

Either a bad wire or you blew the speaker.

Hi check all the wires. Sometimes with the vibration caused by sub woofer can disengage.
Re-plug all wires again and see if that cures the problem

Sounds like you have no signal going to the amp. Check th RCAs.

you know the more people i tell the less people know. A cd player in a car has the lifespan of about 4 to 5 years max and we in europe download everything to an iplayer then play our music thru the fm radio(saves space and anyway CDs are now obsolete)who listens to a radio when its all online.....and you can use your iphone for satnav/radio/iplayer.all in one....i even use mine to watch the world cup.....

Yes you are correct, if it isn't extraordinarily loud it is simply the rear projection of the TV. If the noise was really very loud, it might mean you should contact the manufacturer, but otherwise, everything should be fine.
Good luck!! EJ

wire from battery(normally red) to 12v+, really skinny wire(normally blue) to remote, black or silver wire from ground to grnd. No you dont need the converter as long as you have your rca from asftermarket cd player to your amp(preferred way). You might have also bridged your amp with your speaker wires which would cause your system to run on a different ohm which would cause the bass to get louder then overheat you amp which would turn it off.

The only thing i can think of is the amount of power surging into the speakers is too great and they are cutting of to avoid blowing out. I have a similar issue with my surround sound if i turn it up too loud.

sorry for the late reply. im using windows. im quite sure that there's no virus involved with the distortion of my sound. this is what happened.

1. im surfing the net while listening to music(full volume)
2.)then suddenly the sound gets a bit distorted(jumps,skips)
3.)then everything hangs up which forced me to reboot
4.)the windows loading screen became too long(like 5mins) before it takes me to the main desktop(start up programs loads like 48 years also).
5.)when i play music ,the sound is very much(like alien,"rrrrrrr")

i tried reinstalling the drivers but nothing was fixed. i've even tried Regcure.

i just formatted my notebook and voila its back to normal.
i dunno but i think playing loud music using laptop, or in my case notebook speakers would cause this problem. im using external speakers now and i've got no problems. i just hope that there would be a fix to this problem so that i wont have to reformat if the problem occurs again

I had to add the sure connect antenna on one vehicle and it solved it. Doesn't make sense since one car would run one receiver and had no sure connect but the one receiver needed it. Anyway-works for me fine now!

sounds like you have blown speaker swop them over and see if it works, if so you need repair shop
