OK, Here is the problem. I have a JL 1000/1 first edition. It is in a 2004 Yukon XL pushing 4 12W3V2 D4's. When Its hitting hard the amp does not cut all the way out but it reduces the power significantly. It doesn't do it all the time but it happens a lot. I have stock everything. 0 guage wire. I had a vold meter on the amp and the lowest voltage is 9 volts. The low voltage light never comes on. I need to know whats the best option to eliminate this reduction in volume. It is driving me absolutly insane. Thank you for your help
