jl 1200/1

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

No one does it like jl audio

I have run many systems over the years but none have compared to my current setup the staff at sonic have always led me in the rite direction this system rocks will blow you away crystal clear clean audio with all the bass one could ever want or need Once again thanks sonic

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!!

Great experience from beginning to end

All I can say is wow this sub is a beast this is a very very impressive subwoofer power hungry but if you have the juice to push these subs you are in for a treat. 4 weeks in and the sub is just hitting it's peak sounds great I have had kicker jl w3 has both beat. You cannot go wrong here I'm only feeding it 1000 watts and handles all with no problem no distortion no clapping just very low clean sound

UNEXPECTED

I wasn't expecting this to be so clean and smooth reminds me of a beefed up polk mm sub. Its very clean and smooth on higher end freq which I really enjoy. It's power hungry you need atleast 1500 rms clean unclipped to really open these up. I thought id get away with 1000rms since the subs efficency is so high at almost 94db but it needs more so if you buy this trust a stranger at give it bare minimum 1500 true clean rms not a cheap hifonics 1500rms get a cea certified quality amplifier thats efficient and enjoy this clean low loud monster. This is not just a spl sub.

Little Beast

This amp is worth the price. It produces strong, clear, and precise bass. It will not strain your battery or alternator, just be sure to run a quality 2-4 gauge power and ground. This amp will outperform any 1200 watt amp on Earth, as it should for the price!

We will see

Have one 1200/1 supplying a 13w7. That amp fried. Sonic replaced it no questions asked. This was prior to the Garmin buyout and warranty reduction. Just ordered my second 13w7 and 1200/1. It’s 12/13/25. Amp showed up with a Nov 3, 2023 build date. New stock over 2 years old. Hopefully it’s actually new and not a referb!?
