what brand did you buy? i did some recent but had no issues with blowing fuses.... if i get a chance ill look at the harness's but may be difficult for me to see since i have a custom box on one side and amp on other which i may have to remove to look at the harness's in question if i remember right i think my harness's were a little different from left to right but i m not 100% sure but i recall them looking a little different...
