Hello, ive recently put a second amplifier in my car and that has caused the battery to start dying, this caused the car to take longer to start up and eventually i trashed the amplifiers (one broke,. and my 2000 watt BOSS wont get out of protection mode) but ever since i put in the second amp my car has taken a long long time to start, i eventually replaced the battery and now it dies on cold starts in the morning, i get up at about 430 am and its cold enough where the vehicle wont stay running without feathering the gas, in the afternoon it just takes about 3 minutes of solid cranking and doesnt stall, ive replaced so much crap on this engine i just sunk 2000 dollars into suspension components please help!!!

side note, does anyone know sites more aimed towards car audio as well? i would like to get the amplifiers fixed as i have 3 subs but nothing is running them

 

what have you replaced on the engine, spark plugs, spark plug wires, 02 sensors, any of these been replaced?

 

Seem like you think its the amps, The only thing the amps could do is drop the voltage below spec, To test if this is the case. simple disconnect the amps and drive the car one day. The next day if everything works then your right. If its the same then something else is wrong. Cranking issues like this can be cause by low voltage and/or low fuel pressure, weak spark, a lazy/dirty IAC motor exhaust back pressure, cruddy intake/valves, computer or sensor issues and I am sure some things I am forgetting.

If your AMPs are installed right they should not cause a starting issues. There should be a power feed wire from your stereo to the AMP, the AMP should not power on unless the stereo is on. If you watch the stereo should shut off while the car is cranking, meaning the amp should not be drawing power while the car is cranking.

 

today i just replaced the plug wires which got rid of the misfire, earlier this summer i replaced plugs, last year around this time coil packs, earlier this year starter, yesterday fuel filter, and earlier this week battery (since then i have removed the subs whether or not it is effecting my engine starting i simply cant run that setup without a better alternator at the moment)

 

probly be a good idea to run some injector cleaner through it, or have them cleaned and flow tested at a injector shop.
