JL Audio 500/1 Car Amplifier

Is a very powerful amp and other brands can compete with it. This amp produces clean bass, with out distorting the sub's.

The original Slash amplifiers set new performance standards for automotive amplification and became the best-selling premium mobile amplifiers in history. The new Slash v2 amplifiers build on this legendary technology platform, enhancing it in a variety of key areas, like radically improved thermal performance, a beautiful new stackable chassis design and dozens of tweaks aimed at improving performance, flexibility and reliability. There is no magic and no guesswork here... just pure technology, refined to the last detail

This is a very high quality amplifier. I just installed two of them powering two Rockford T112D2 subs. The variable impedance tolerance is a really nice feature, though I feel that if it were to be set differently (such as 1000w rms @ 2ohms vs 500rms @ 4 ohms...) then this would be a much more useful amp. 3rd party ratings already place it around 600rms in a few tests. The distortion is low, but an MB Quart amp rated at the exact same specs is about 1/3 the price. I give it 5/5 for the quality, it of course does what it's supposed to and very well at that, but I feel like the price paid is really for the brand name. I'd say buy this if you feel the need to show off your amp all the time... but you can get equal specs and quality for less $$$ elsewhere. If you have the cash, you can't go wrong really with JL.

This is a small but very effective and accurate powerhouse, delivering power with no loss over time even with utter abuse, I had my first 500/1 problem free for 5 years, it pushed a 500 watt subwoofer until I decided to switch to a new car and upgrade to the cooler black version 2007 model.

This JL AMP is more powerfull then some of the amps my friend have that are rated for more power. A 3600 Watt M.A. Audio amp didn't even compare. and 1400 Watt sony Xplod was also no where near the Jl's output.

Great everything amplifier, JL comes very highly recomeneded.

I wanted an amp that I knew could handle the power, no matter what I wanted to run to it in listening range. I am running two JL W6v2s in a SUV (so no backseats between the trunk and cab). They are both powered to the point where it hurts my ears and the amp is about 50% gain. My amps are under the seats and after listening to the point where my Alpine MRP-F450 channel overheats into protect mode, the 500/1 is still cool to the touch. Sounds amazing, I had the subs hooked up to my old Jensen amp before buying this. Not only was the volume and power drastically improved, but the quality of sound was as well and even more than I could expect. I recommend this amp to anyone who can afford it. I've done A/B comparisons with my friends 1200w Insignia amp and can clearly hear the difference in the under $100 bargain amp with the real thing. I was worried about getting the 500/1 instead of the 1000/1, since the subs are rated well over 350w each, but when I turn the amp up any higher in rap I get a headache. I usually don't turn it as loud as could for rock, but I know the amp could handle it. Get this amp, do it.

I recently purchased a JL Audio 500/1 Amp to mate up with my JL 10 W7. I am very impressed with the output power as well as the versatility. One nice option is it's signal sensing turn on option as well as the standard 12V switched turn on. Although the 12V is recommended, I use the signal sensing turn on due to my use of a OEM head unit and one less wire to run.
One draw back to the signal sensing turn on is that there is quite a delay. I have to crank the volume to get it to turn on, but once it's on... it's ON!!
Also, to a novice car audio enthusiast, there may be a little difficulty setting the input voltage. If the manual is read, and followed properly this shouldn't be an issue.
Overall, I am very happy with the amp, and would deffinately recommend it. JL knows it's audio!
