I installed a pair of 12s and an amp in my LS430 using a line converter. I tapped the stock sub and ran the LLC off that. Problem is, the LLC starts getting super hot and starts to melt. Any idea what's going on here? My car audio place wants to tap behind the stock HU. I asked why they don't just tap right before the stock amp in the trunk and they gave me some BS answer. Anyone have the wiring diagram for the stock LS430 amp? Thanks
