Waaaay back in 2005 I posted on a car audio forum asking if anyone had the manual for an Alpine 3553 amplifier. I had the amp but no manual and couldn’t figure out the power ratings and whether it was stable at 2 ohms. Unfortunately Alpine themselves didn’t seem to have it in their manual database.
Some kind soul sent me what they had of the 3553 manual along with the 3552 and 3554 manuals, from this I managed to figure out the information I needed. Every month or so I now get an email or two from people who happen upon my post asking me if I’ve still got the manuals, just goes to show how, after all these years, the 3553 is still alive and kicking!
So, for anyone who’s after these manuals here are the files as I received them:
Note: By posting these here I am not claiming any right of ownership of the files, which of course belong to Alpine.
@Alpine: If there’s a problem with me hosting these files please let me know and I’ll duly remove them (and please add them to your manual Database so people can get to them!).
