I upgraded my alternator and put an optima battery in my car a few days ago and everything has been awesome (no lights dimming) until yesterday.

I was running some errands for about an hour and was on my way home and my stereo cut out, but the deck was still on. I opened my trunk and found two of the 4 tube fuses in the 4-fuse distribution block blown so I decided to replace all 4 with bigger tube fuses and the one under the hood just for good measure. After doing so, the deck still came on but there was no music comming through the speakers. I checked all the wiring in the trunk and everything is still hooked up nice and tight, the deck & amps turn on etc.. but no sound at all.

I am baffled as to what's going on and I am just wondering if anyone has any idea's as to why it may be doing this.. I have tomorrow off so I have time to mess around, and the earliest I'd be able to get my car into a shop is probably tuesday or wednesday so I figured I would ask everyone on here.

I havn't done anything to my stereo in a while so I havn't had any problems for a long time until I added the second battery and bigger alternator, but I"m not sure if that would have anything to do with it. This is what's in the car if it must be known

Maybe the subs are blown? Do all of the speakers run off amps? The subs/mids/highs? If so are all of them not working?

there are also fuses on the amps, be sure to check those.

I highly doubt the subs are blown.. all my speakers are running off amplifiers, yes the mids and high's too and none of them are working.. everything cut out all at once and yes the fuses on the amps look good too. hmmmm...

Step One - Put the proper sized fuses into the fuse holders. They blew for a reason.

Step two - use a multi meter to determine if you have power at the amp, fuse blocks, etc. Find out how far the power goes.

Step three, have a professional look at it and fix it right............................

Fuses blow for a reason, not to allow you to put bigger ones in..............

Yes sir! You have a good point. Is there any possible way that a bigger alternator/another battery added to the car could in any way cause something like this to happen?

I find it rather strange that I never had any problems until I upgraded those things. [img]graemlins/banghead.gif[/img]

If there was a colossal failure of the voltage regulator but then there would be a problem with much more of the electical system than just the amps. Something indeed has caused the amps to fail. The Rockford amps do not have internal fuses, thus the need for outboard ones. My guess, something dead shorted and back fed to the cd player taking out a vital circuit. Unplug all the rca cables. Find a discman and fire it into any one of the amps. If the speakers come alive, it is indeed a source or wiring issue from the source that is the root problem. If they are still dead, then whatever caused the failure has taken out 3 amps (WOW MAN). Unplug all rca cables and run a new temporary one over the seats. If you have a amp that you can borrow, do it to test the cd player and speakers with.

Sounds good, and you are right the rockfords don't have internal fuses, but the soundstream amp does and it is perfectly fine.

Awesome, so I just paid $30 to get my stereo fixed only to have the deck completely turn right off. I"m glad I took it to the "professionals."
