The speed of service and delivery fused at different Amps voltage to purchase appearance is always a great addition and skar audio is always a head of the game I love skar audio I have been running their RP series amps I have all of them except the 4500.1 I bought this for my 07 Wolfsburg jetta with a 15 dual 2ohm down to 1ohm with the RP 3500.1 and it slumps and hits so low the skar box foe my single 15evl series..is tuned to 30htz..n when it hits that level and lower man u know it ..o call it the 23htz (23hurter)..explosive always excellent quality and functionality thanks 😊

Cover too loose.

Size: 300A Fuse Holder

Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.
