P500-1bd

The following review is for P500X1BD, which is a part of the bundle you are viewing.

I put this amp in my daughters 2003 Mustang and paired it with a P3 12 inch sub in a ported box. The two work great together. Set-up was no problem on the amp. She has had no problem with it at all, but remember she also gave everything time to break-in. Birth sheet read 286 watts @ 4 ohms, 471 watts @ 2 ohms, and 745 watts @ 1 ohm. I wired the sub at a 2 ohm load by-the-way. So the amp is running at a comfortable ohm load. I would suggest anyone get the PLC 2 remote control for the amp. My daughter loves the remote, but so do I.

Excellent car audio power cable

The following review is for RFK4I, which is a part of the bundle you are viewing.

Excellent product. Easy to work with. I bought two sets so I could wire a four channel amp and have extra power wire to do a "big three" wire project under the hood. Highly recommended.

true

The following review is for RFK4I, which is a part of the bundle you are viewing.

I love this wire it's so much better than my old 4 gauge wire. I put it next to the 4 gauge i bought from a local audio store and the rockford wire was twice as big and way more flexible. Everything in this kit is amazing and it is def worth the price.

amp install kit

The following review is for RFK4I, which is a part of the bundle you are viewing.

very nice kit for the price paid. wire is extremely flexible for gauge. power wire is long enough to go from battery at the front of the engine bay, through the firewall, under dash, under the carpet, down transmission tunnel, under rear seats, into trunk and still have 2 feet to spare. this was done on a 93 chevy beretta, so bigger sedans and suvs may need more wire. i'm very pleased with this kit and would buy again

awesome amp

The following review is for P500X1BD, which is a part of the bundle you are viewing.

Everyone says Rockford isn't any good since the started manufacturing overseas, but the thing is, so did everyone else pretty much. I bought this amp to run one 2 0hm dvc ten because it was pretty close to ideal rms at 1 0hm..... just a little under. But the amp was actually about 300 watts more than the 500 it was suppised to be at 798 watts @ 1 ohm. The setup was super easy. Their clipping indicator light was spot on against an oscilloscope. Rockford makes good stuff and always has. This amp sounds great runs cool and makes a lot of power for its rating. How can you talk trash about that? It does more than it says and that says it all!

All i can say is wow. Unbelievable power delivery and a crisp clean signal with no distortion or signal loss issues. RF has always been amazing with their products and this kit just adds to that reputation.
