## Questions & Answers

**Q: Is this ofc (oxygen free copper) cable?**
A: Free from Oxidation!means is Better than aluminum

**Q: The led doesn’t stay on is that a problem ? It reads when I first start the car but a minute later it shuts off, it is full I believe but no display**
A: They usually do that every now and then but it’s actually working. As long as the display never completely shuts off it should be good to bump

**Q: Does it come with speaker wire?**
A: Yes it does

**Q: If I have a Capacitor do I need a second battery**
A: No, the capacitor is connected in parallel with the battery close to the amp. The kit has very good  instructions,  fairly easy installation.  Hope this helps.

### ⭐⭐⭐⭐⭐ Good product.

### ⭐⭐⭐⭐⭐ It works and it's worth it

### ⭐⭐⭐⭐⭐ The kit you need for amp install!
*by P***Y on January 26, 2020*

Make sure you also order a power distributor to split the power line before wiring amp & cap. And maybe another ground as 3ft wasn't long enough for both amp and cap for my install. I was quoted hundreds of dollars to run a new power line from battery to amp, much of it was labor hours, but both places charged TWICE THE PRICE just for the amp wiring kit. NOT INCLUDING CAP! So glad I decided to run this myself, especially as my '09 Rav4 driver side firewall grommet already had a hole punched that fit the 4GA wire! Might be slightly more difficult if you need to drill new hole, but if you're AT ALL handy, you can YouTube & DIY easy enough. Definitely took a few hours to pop off all the interior side panels, the stereo head unit, and run the wires, but nothing too technical or mechanical or requiring specialized tools and totally worth the afternoon in the driveway/garage.
