ok i have multimeter. i am powering my 2 12' alpine type-r's rated each at 300RMS with a BX1500D at 2ohms at 1000watts rated. its a little overated so 900watts. so u place the two rods on the corresponding + and - on the amp terminals. i i keep getting the reading i need but its only 1/4 up on the gain and i cant hardly hear any bass. when i turn the gain up i can here it. but the gain isnt setup properly. help needed. thx.
