I have a lanzar 1600 watt amp. I hooked it up in my car with 2 r10 alpine subs. it was working just fine and now my subs are not working. the fuses are all good and everything is connected right. The power light on the amp does not come on like it did. could the amp be blown or is it another prblem?
