They have been installed for about three months and no issues at all. They have stayed in place even with the roads i have to drive on so im more than happy with them.Would easily recommend.

Just as other posts say, these adapters won't fit side by side due to their size unless you turn one some. After all, you are trying to put two 0 gauge wires where two 4 gauge wires normally go. If it looks like the adapters will rub/touch I suggest using the plastic piece that comes inside one of the adapters to act as a barrier. Just split it down the middle to make a flat piece and sandwich it between the two adapters. The shaft of the adapter has a flat spot on one side so that the port's screw can have a more secure hold. Both the 0 gauge wire and the adapter fit perfectly.

These are nice. Just a heads up though. I was planning on running 0 gauge into a power distribution block with one 0 gauge input and two 4 gauge outputs and the pins on these are no long enough to go into the block and be grabbed by the screw. The pins are also quite large if you amp has a smaller gauge input. I am just going to use them for my grounds so I just ordered some Knukonceptz ofc 4 gauge for the power wires. Scoche efx anl fused block FYI.

Best reducer to make 0 gauge to 4 gauge. High build quality, though there is a chance that it might not be suitable for slots that are placed side by side since they are quite wide. But well suited my purpose to wire a jbl gto mono block amp

These fit and work perfect but if you’re positive and negative are very close on you’re amp they may be a little too close

Needed a couple of these to make life easier taking my amp out of the trunk when I have to move large items. Excellent quality and correct sizing.
