Re: LED is on, but no sound
If the LED is on then that pretty much means that your remote wire is functioning properly but that does not always mean that the amp has power
The 40amp fuse connects to the main power wire that is run from the battery to the amp and must be connected at the battery end NO MORE THAN 18 INCHES from the battery but the closer you can put it to the terminal the better since this fuse protects you car from extreme damage or fire that can occur if the amp power wire should happen to short out. TIPS: Power wire from battery to amp needs to be at least the same size or bigger than recommended for the amp (the longer the wire the thicker it should be) Always Run amp power wire through a rubber grommet to the engine compartment to avoid wire short that can be caused when car parts move and flex during driving Run power wire on separate side of car away from RCA cables to avoid noise in the system

try using an ipod or mp3 and hook it up directly to the amp input section-if its lit up and you get sound then youre not getting signal from your deck and youll have to track that problem down at the deck-if you still dont get any sound by connecting directly into the amp inputs then you may want to check all amp settings and be sure that your set up right and if it has external fuses make sure that they are all good and if it still wont give you any sound than take it in and get it checked out-hopefully its just not getting any signal cuz if its the amp then sorry to hear it-but good luck
If your alternator and battery are in good condition, you probably don't need a capacitor. At maximum output, the 801S will need to draw a little over 30 amps at 12.8V. The specifications call for 8-gauge power and ground wiring and a 40A primary fuse. The Vibe's electrical system should be able to handle it OK.
If the voltage is dropping to 8v, it sounds like there is a problem with either the B+ line or the ground connection. You should also check the voltage across the battery terminals to see if the voltage is dropping at the source.
The amp may be going into protect mode. Disconnect all speaker wires from the amplifier's terminals. Also disconnect the RCA cables from the amp. Does it still go into protect?
Insert a 20 amp fuse in the B+ line and try to power it up. If the fuse blows with no speakers connected to it, the amp probably has a blown channel.
Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?
I have a Digital Audio model-DA2200W, Was listening to my tunes loud as always....then the subs quit bumpin...checked the subs cuz i thought i blew em...theyre fine...The power on the amp is still on...green light and all..just no output..I opened it up to see if anything looked burnt looks fine...is it toast or can i fix it??
