HD1200/1

JL Audio's most powerful HD amplifier employs our advanced Single-Cycle Control switching design and R.I.P.S. technology to deliver 1200 W of clean power into any impedance between 1.5 and 4 Ω, giving you the highest degree of flexibility in designing your subwoofer system. Tight power supply regulation keeps distortion down and maximizes your bass quality. From a pure sound quality perspective, we invite you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price.

While targeted primarily to subwoofer applications, the HD1200/1 is a wide-range amplifier and can also be used to drive high-performance mid-range speaker systems. This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.

sweetness

Bought this amp to run a 12w6v2, and wow, thats all I have to say. well worth the money, and if I want to add a second sub I always can. It will handle them both easy. A bit pricey, but im sure it will be the last sub amp i buy for a long time.

Bullet proof

I use one of these to power a 13w7 and it gives it every thing it can handle and more. The noise floor is non existent like the amp is silent completely until the music starts. And it barely gets warm even after hours of play on long trips and myself I have never had a shit down or anything. And all I have for electrical is stock 120amp alt 4 Gauge ran back to a 1000 watt capable secondary battery and 1/0 run from that bat to the amp and it’s so efficient I barely have any headlight flicker. I have been banging this amp for 6 years and could not be happier. I wonder how many so called better for cheaper amps have burned up in the 6 years I have had this amp. Yea it’s not cheap but if your serious about your audio like me and you plan to keep the stuff or actually want to get something back out of it if you do sell do yourself a favor and just save a little longer and get the good stuff the first time instead of doing like a lot of noobs and saying well this amp says 1500 Watts at 1ohm I will get that for half price, trust me you ain’t getting what you think. I dare you to compare this amp to any amp under 5k Watts that’s a unregulated amp and I bet this one in the car actually playing music is louder. I myself have a DC 2k and the HD 1200/1 is every bit as loud or louder on less electrical and less cone area on the sub.

Unreal SQ and SPL

bought two of these bad boys to power 2 12w7AE's in a custom built ported box. however i only hooked up 1 amp to 1 sub.. and being honest it was twice as loud as my previous setup of 1 rockford t2d412 powered by a pdxm12. i cant imagine hooking the other amp and sub it would make me deaf. the sound quality is superb, doesnt need much power it will stay at 1200rms even at 11v and barely get warm. i would recommend this amp to anyone and everyone i know. ive had several different brands over the years and this one is by far the best if you are looking for both SQ and SPL

Wicked Amps

Again, I did a lot of research on the amps to pair with my JL Audio C7’s. And these were by far the best. Very well made and with the intelligent power supply, They get nowhere near as hot. I have fans wired into my system which have yet to come on. The sound is amazing, and you hear every level of detail with no distortion. Paired with a my 13W7AE, this thing is a beast!!
