User Reviews about JL Audio 500 1V2 Car Audio 1-Channel (Mono Block) Subwoofer Amplifier 500 Watts

Great Amp- tons of user controls: adjustable LFE and cutoff frequency with 12 or 24 dB/octave dropoff rate. Also really like the high pass filter that can knock of the sub-bass frequencies in the range of 10-25 Hz. Great, solid amp from a solid seller. Shipped fast and came in great condition with full warranty and serial info on box. Have pushed it hard for hours without fail- EXCELLENT match for any speaker in the w6 lineup, I've got it run to a single sealed 10w6v2 and it hits hard and deep, and responsive like I've never had in any sub. Yet to find a single genre it didn't sound very clean on. -- Affordable, Clean Power

I bought this amp and had it paired with the JL 12w6v2. I carefully considered this sub/amp combo since it was going to be a first system that I put into my car. This combination maybe a little too much for my 4 door sedan, but it was well worth the money spent. The amp itself remains relatively cool under conditions of hard use. If your looking for one of the best amps that your money can I would go for this one. However, if you don't need a lot of bass consider something else. You could probably get a package installed for this much. I hope this helps who ever reads it. -- JL Audio 500/1v2

shipped fast & came as described, works well with the kenwood 12" sub
