Vehicle is a 2002 f150 and I will be feeding 2 SA-12 1500 watts total. What, if any, electrical upgrades do I need?
Thanks man. Stupid question but how do I go about checking my voltage drop?depends on the amp you get. id do a minimum of the big three. see what your voltage drop is after that and change your battery under the hood to a AGM and add a HO alternator if necessary
Thanks man. Stupid question but how do I go about checking my voltage drop?
Where exactly do I connect the positive and negative from the DMM? sorry this is a dumb as hell question lol.using a multimeter, usually called a DMM. you can buy them for less than $20.
I don't like the cheap yellow walmart innova ones, terrible accuracy. I've been pretty happy with my $18 DMM/amperage clamp from harbor freight made by centech
Depends on the amp, if thats required by it then yes, if not you will need some 0/1 gauge....your 2002 F150 has either a 4.6 or a 5.4l motor and a pretty strong alt from the factory so depending on the amp for your subs, you might be able to just get away with the Big 3 upgrade as well as a new battery up front and be ok, depending on the condition of your current alternator.
Gotcha, thanks man. My f150 is actually a 4.2 liter. According to sonicelectronix, the maximum wire size for the amp is 8 gauge....lol wtfHook up the positive and negative leads of the DMM to the power and ground inputs of your amp, while its at full tilt so you can see how bad your voltage drop is.
