I have one alpine type r 10d2 hooked up to an alpine mrx m100. This amp is 1000 rms and the sub is suppossed to be able to handle that. But i have the gain set to just above halfway an when i turn up the volume of the headunit to 36-37 (goes to 50) and itll just bottom out. Im pretty sure all the wires and all that are ran rightt. What could be causing this or is that really all the sub can take? And also i put this against a rockford p3 12 and the rockford just completely blew mine out of the water.. And everybody said the 10d2 could hang with a p3.. What is going on? What do i need to do?
