I just got 2 12" JL W1s with a pioneer cheap headunit and a JBL 700watt amp and there in a sealed box, was wanting to know how to tune the amp and also how loud i can go i really dont want to blow them and idk how long the break in on them is. thanks for the help

 

run the crossover low pass at 80hz. set the gain until it starts distorting and never try to add bass thru the HU
