If i get into the throttle to hard it will fall on its face, i have changed the distributor cap, rotor, speak plugs and wires it has helped a little bit but still acts up, 2. i just put a 10 in sub powers by a 600w fosgate with a jensen VX4012 when the bass drops really good the voltage drops i tested the voltage at the battery, alternator and right at the sub, there is not drop at the battery or alternator but at the amp it will drop as low as 11v, 3. when i use my lights at night or turn signals i get a drop and my truck has a hard time staying running at night with the lights on. What can i do to prevent this big voltage drop.</p></blockquote><p></p>
