[QUOTE="DRBOOM, post: 8665775, member: 676005"] Hey mate, Thank you for posting your issue here. Unfortunately the pics don't give us a good impression of your sound system configuration. It seems like you are running different subwoofers and loading the amplifier with difference resistance?? What would be helpful in this case is that you list : [LIST][*]your current sound system components eg: [*]4 channel amp running pair of front component speakers; [*]2 monoblock amplifiers running a pair of 12 inch 4 ohm woofers, wired to 2 ohm load; [*]1 monoblock running a band pass 4 ohm subwoofer; [*]1 monoblock running another pair of 4 ohm subwoofer; [*]1 x power cap to run the subwoofer amps; [/LIST] This will give us a better impression on how its all wired up and make it easy for us to determine the cause. IMHO, most likely cause is low impedance causing the amp to go into protection. Secondly, educate yourself in using a multimeter, its your best friend in car audio installations and its pretty easy to use as well. From your pictures seems like you are chasing SPL scene, would be better to get two SPL 12's in a large ported box to achieve the same or more output then your current gear. Having 5 subwoofers is an unusual configuration not to mention amps / distribution blocks have to be check and secured to avoid any short circuits. Also using the same colour wires for grounding and power is not a good idea, but you can apply electrical tape to the ends to ensure correct installation. :rolleyes: [/QUOTE]
