Description of R1000-1D:

If you want a good Kilowatt of power (1,000 Watts RMS), then you need this Rockford R1000-1D class "D" amplifier! Class A/B amplifiers just don’t do the job when you need this much power. What you need, is sturdy, class D, digital power supply that will give you unparalleled performance and will not drain the battery of your car. Rockford Fosgate’s R1000-1D Amps do just that. The R1000-1D  series 1000 watt Class – D Mono Amplifiers are designed to give you POWER (Power Output Without Excessive Regulation); that means that these amps will deliver to your demands, and react quickly to give you the most accurate sound reproduction possible.

The R1000-1D mono amplifier will give you 500 watts RMS x 1 at 4 ohms and the full 1,000 watts RMS @ 2 ohms. It comes with a high end MOSFET power supply and output stage for great sound and efficiency. The R1000-1D mono amplifier has LED indicators which show power and protect modes. The LED will turn green when the amplifier is turned on – this is the power mode. In Protect mode, the LED turns red indicating low impedance or a short circuit. In protect mode, the amp will shut down to avoid it from getting damaged.

This amp has a low-pass filter  allowing you to adjust the bass frequencies going to your subs.  This also has the famous Rockford Fosgate Punch Bass Boost; so you can customize and adjust the amplifiers bass output.

The Rockford Fosgate’s R1000-1D Amplifier is perfect for 1 to 6 subwoofers in a system.  Since this amplifier is built just for bass, you can be sure your subwoofers will perform at their best.

Description of XK4B1

The DB Link XK4B1 is a 4 gauge amp kit which works with any amp up to 1,200 watts RMS or more (depending on which brand name).  This amp kit is made with true real life RMS ratings, so you get the power you expect.  This kit truly can handle a lot of power.  Other brand names sell 4 gauge kits that have 40 amp fuse, but this one has a 60 amp fuse, so you can be sure it will handle the power of your amp.  The reason this has such a big fuse is because it supports competition grade amplifiers and this is part of the Xtreme series of kits made by DB Link.

It is not smart to go cheap on your wires, if you have a powerful amp.  It will draw extra current and take extra power from your battery, because the cheaper kits can't handle the amount of power the amp is trying to pump out.  This will also limit how loud the amp will go, and the sound will not sound as clean.  With cheaper wiring kits, you will get engine noise and more distortion.  DB Link has been making the best installation wires for many years.  These sell at installation shops for around $119.00; Get it here for way less!

These wires are really really thick and great quality!
