Spedometer is jumping

[itsnotmydaddys]

i saw today on the highway in traffic that my spedometer was jumping. like when i accelerated it would jump up not smoothly at all, and also did it when deselerating. i though it was cause of my system, but seems too little of a system to do that. my old car had 4 12s and had no problem like this. then i turned off the system and it still did it when i wold go over bumps. what should i do, i might take my car into the lm dealer next week. is this covered under my 2 yr warranty. thanks in advance

Mine started doing the same thing after I got my system installed. I just ignored it, hopefully it's not anything too big to worry about.
