So heres the deal,
I just installed a pair of infinity kappas with a boston audio 2ch amp. Everything is brand new out of the box. I have an aftermarket Kenwood HU, Kinetik HC2000 in my trunk. I have the battery in the trunk wired + to + with 250 amp fueses, Knu OFC 1/0 on either end of the power wire and - to - to the battery up front. Off the battery in the rear I have a distribution block with a 1/0 in and im using a 4 gauge out with a 150 amp fuse that leads into the amplifier. The amp is grounded with 4 gauge wire to the battery in the trunk. The remote wire is from the blue remote wire in the back of the HU.
The problem is when I just have my igniton on without the car started, the HU turns on, the red power light for the amp comes on, I get the inital pop sound, and works and sounds great, but as soon and I turn over the engine, the orange protect light comes on and nothing plays at all and no pop sounds from the speakers. The HU is still on and plays. What the hell is causing this? I have checked the speaker connections over again, the power and ground wire, the fuses and everything is all soild.
Also if your wondering why I have a an HC2000 for a little 2 channel is because the sub stage will be going in after this problem is fixed.
Any and all help is welcome. This is driving me crazy!
