YO TS...

imo i think its still ok la to spend a fortune(decent value for money product) on ur 10 year old car...and try to keep away from chap ayam..

when u buy a new car..d item still can b transfer for ur new ride...so instead of have a decent sound outcome later..why not now?..believe me..good sound system can bring enjoyment in ur driving..hehehe

but..in ur case..no soundprofing lah..it will be a waste bcause its untransferable..

fyi..im driving 14 year old car...
