I am looking to add an amp to my setup of a uniden 980ssb and a wilson 1000 on my 2017 dodge ram 1500 with a 3.6l v6 and 160 amp alternator. These are my questions...how many amps can I safetly draw from this electrical system before I need to upgrage alternator or add batteries? Upon looking at amps I seem to have 3 options..RM Italy, X Force or Texas Star that I can get online. Upon review I see that Texas Star requires a crystal for frequencies? Where and how do I get one? I have 2 shops near me and 1 is a hack shop and the other won't even allow an amp in his building! Using a watt meter and turning down deadkey to 1 to 1 1/2 watts for an amp do I need to do more to radio? The last shop I used for years closed down.. I'm really leaning towards the midnight special 250 as I just want a little power to shoot skip but I know I will wish I bought bigger! Am I safe on amp draw to go to the midnight special 500 or 700? Sorry it's so long and thanks for your help.
