[QUOTE="hal keiner, post: 795730, member: 66101"] I am planning my replacement of the OEM Pioneer 6-disk CD changer with an Alpine 9886 head unit on my 2002 ST. In reading several posts on the excellent forum, I see that a 7805 voltage transister/regulator is suggested to eliminate the "pop" in the factory subwoofer when the head unit is turned on (see link below). I plan to follow this advice. However, in further researching the use of the generic 7805 voltage transister in other applications, it is suggested to use a heat sink with the transister. My questions is this, is such a heat sink a good idea for this type installation? I already presume that it is not absolutely necessary, as it is not mentioned in the below linked thread. However, if it is a good idea for the long term life of the transister and/or subwoofer amp, then I would go ahead and install a heat sink with the transister. The replacement cost of the transister is not the issue but rather the trouble of replacing it if it were to fail often. Thanks in advance for any input on this. http://www.mysporttrac.com/shared/msgboard9e.asp?BOARDNAME=MSG&VIEW=1110014 [/QUOTE]
