So, I just got all the custom installation fabrication done and fit everything in and hooked everything up...

only problem is that when i hooked it up my truck wouldn't start so...

i got a jump and a charger and could barely start both
then i got it started and turned it off and tried to turn in on again and it wouldn't


took the fuse out of the inline fuse and then started it without charging it or anything

so my amp is taking to much power on start but not actually draining my battery,

What do i do? What can be done?

    May be a stupid question but you don't have the remote wire hooked to a constant 12v on those amps do you? If so, that means they would always be on and draining the battery. Check to make sure the amps turn off when you turn your truck off.

    no i have the remote wire hooked up to my head unit which turns off when the car turns off
    but, the issue isn't draining the battery its that its taking to much power from the starter to turn on the engine.
    would a capacitor fix this problem
    where is a great location to hook the power wire to the battery?

    What vehicle? You also need to give more details. When you try to start does it turn the engine over but very weak... do you hear the starter click... complete silence??

    I cannot see what you describe happening as being the fault of a correctly installed and correctly functioning amp. Disconnect all wires from the amp with the exception of the main power wire, which should go directly to the battery and be fused near the battery. Try to start the vehicle. If it does start then reconnect the remote power lead and try to start the vehicle again. If it starts continue reconnecting wires until the problem surfaces.

    If you are 100% sure your wiring is correct, try a different amp.

    I would try the steps I suggested. I forgot to mention the ground but ground the amp and hook up the power wire. Do not hook up the remote wire. See if it starts.

    I agree the amp should not cause this problem. The amp at idle is drawing basically nothing. If the starter is spinning but the engine is not starting its not a battery issue anyway. Let us know what you find out.

    If the starter sounds like a motor turning really fast and nothing is happening...broken tooth on the flywheel.

    Could the "Battery" just be in a **** state and can't do both at the same time. Have you had the charging system checked the battery checked?

    Check the voltage with a volt meter while starting if it drops below 11 volts its a **** battery but if nothing is catching like you said a tooth is chiped

    Even if a "Good" battery could just be in a low charge state, due to a "Heavy Listening" session. If you suck move power you better have a Nice battery and a Hell Amp output Alternator.

    He already stated that he can jump start the truck and it would start with the amp disconnected so it does not sound like a busted tooth.... also a spinning starter does not necessarily mean a busted tooth.

    It could be a bad battery but for a correctly wired, correctly working IDLE amp to prevent the truck from starting, the battery would have to be complete, total crap to begin with.

    Sounds to me like an incorrectly wired setup or he is inadvertingly leaving out some important details. Regardless the troubleshooting steps I suggested would narrow it down but that parts up to him.

    Or here's an idea: it wouldn't solve the mystery, but put a switch in-line on the main power line that goes to your amp. Wait for the truck to turnover, and then flip the switch.

    might want to put a solenoid or a high amp relay in there hooked to that switch

    Check the flea market for high amp car audio relays :D. I hear someone named BaggedLancer is selling 2.
