What else can it be?

[georgegto]

Yesterday i installed a subwoofer that has a build in amp...so it was something wrong with it and my battery was over by the night..Then i tried to startup the car and it just happens nothing, checked spark plugs, changed battery and still the same..The engine dont even make a sound that is trying to start when i turn the key.

Can someone tell me what else should i check?

UPDATE...So i made a self diagnose to my ECU 2day and i got code 11=crang angle sensor...

Is there something that i can do so i can fix it before buying an other one?BTW my engine is CA18DET

battery took a ****

battery changed, can it be the starter motor?

Check you wires. Maybe you hooked something up wrong. Check fuses. The list goes on. So just back track what you did for the install and make sure its right.

The unit should have inputs for constant power and turn on power, it sounds like you have the turn on constantly on.

He code a CAS code. You may have a bad ground. Check the main ground from the battery to the chassis and as many of the auxilary grounds in the engine bay that you can find

The only cables that i installed extra for the subwoofer was a power cable direct from the battery to the trunk, rca sound cables and a short ground cable...all that cables now are gone, i unistalled them again but the problem still the same, same 11 code from the ECU crank angle sensor.Can it really be that the problem?

Check the connections on the CAS. Disconnect it then reconnect it.

Also, try disconnecting the negative cable for like 30 seconds. This usually resets the codes in the ECU. See if it comes back
