Mine are getting weak.

 

yes they are.. but how you go about replacing them is another story.. private message Washington DC Maxima aka Mod of Maxus Forum.. he had to replace his due to warrantee .. he can give you the steps he went through

 

yes, did you buy them from stillen? as long as you own the car, they are under waranty. did you send in the waranty cards?

 

Yes, I got them from $tillen. I'll have to look
to see if I'd sent in the warranty card though.
I assume that the procedure would be:
1-buy another set from $tillen.
2-install new set & remove old set.
3-send back the old set for refund.

 

Okay. Just called $tillen
and they said just buy a new
set and send back the old
set for refund after the installation.
No warranty card is necessary since
they have you on record from the
first purchase.
