More Power from a Smaller Chassis

The monoblock JL Audio HD1200/1 HD series car amplifier delivers unreal power in a very small and convenient size. Often times smaller amplifiers will lack power or even quality, however with the new JL Audio HD amplifiers this will not be the case. The HD amplifiers are equipped with amazing technologies like Single Cycle Control, which tracks audio signal and compares it to the real PWM waveform and then corrects it accordingly each and every cycle. This helps to control distortion causing mechanisms improving the quality of the amplifier tremendously. HD amplifiers also feature the R.I.P.S. System, R.I.P.S. stands for "Regulated, Intelligent Power Supply" and ensures consistent power delivery over a wide range of battery voltages and load impedance's. This means you will received the same power output at 4 ohms all the way down to 1.5 ohms each and every single time. With dual mounting options for added versatility and advanced heatsinks with vertically oriented fins for extreme heat control, the JL Audio HD amplifiers are unmatched by other amplifiers in the same class.

Great amp make sure you upgrade your electrical alternator and battery uses a lot of power.

sweetness

The following review is for HD1200/1, which is a part of the bundle you are viewing.

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

The following review is for HD1200/1, which is a part of the bundle you are viewing.

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

The following review is for HD1200/1, which is a part of the bundle you are viewing.

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

The following review is for HD1200/1, which is a part of the bundle you are viewing.

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!!

Incredible Sound Quality and Punch

The following review is for XQW124, which is a part of the bundle you are viewing.

Got a pair in a 1.5CF per side, FoxAcoustics box, tuned to 35htz, and wired to 1 Ohm, delivering 1100 RMS on a massive D2400. The sound quality is second to none. Transitions are tight and very pleasant. I can feel the percussion and get plenty of SPL. Beat the REAudio S E X hands down. Amazed at the quality of the woofer, and what it delivers in such a small enclosure.

Install review

The following review is for XQW124, which is a part of the bundle you are viewing.

The construction of the sub looks solid and it has nice terminals(pre wired for 2ohm).
That being said it's really a 12.5 inch sub and may not fit in pre-made boxes such as the belva example I ordered with mine. I had to cut at into the side of the box walls to make the sub sit into the cutout.

Will update on how it sounds in the recommended sealed box ~1 cu. Ft. Once I have finished my install.
