  1. Nothing. It would be no different than connecting the test light to either battery post. The light has so much internal resistance I'm not sure it would even allow the starter solenoid to engage, let alone energize the starter and power all the other electronics

    correct i did a test on this in lab one day ( studying electronic engineering ), where we had a simple series circuit with some resistors, with a steady 18 volts power supply. i used place an analog meter on one of the resistors to measure the resistance ( same as an analog test light in this sense very high internal resistance ), and had a digital meter measuring the current at the same time. the current was about 45 % less when i had the analog meter ( or in this case the light ) in the circuit

  2. don't doubt the quality of then sundown sa 12s, I personally thing they are the best 2.5 inch coil sized 12

    1 18 has more cone area, then 2 12s. so get that right first.

    cone area = pi x ( r x r )

    r= radius

    pi=3.14

    1 18 has about 254.47" of cone

    2 12s has about 226.19" of cone

    if your going for numbers 1 18 is proven to put out better numbers then 2 12s. taking into fact which subwoofers are used

    you will probably get better numbers with the ns 18 over 2 sa 12s with the right power

    however the 12s will be more musical, and require less room
