Notes from JL Audio:

*If you connect a load higher than 4Ω nominal, power will drop by half with every doubling of impedance above 4Ω stereo. If you connect a load lower than 1.5Ω nominal, the amplifier protection circuitry activates a "safe" mode which reduces amplifier power to protect the circuitry from failure (the LED status indicator on the control panel will light up amber to indicate that this has happened). See page 14 for details.
**We do not recommend the use of “copperclad aluminum wire” or "CCA" wire because this wire is significantly less conductive than pure copper wire. Only use pure copper power wire, such as JL Audio’s Premium Power Wire. Tinned copper wire (silver color) is acceptable as the tin-plating is only a very minor component of the wire.
**The HD1200/1's "+12 VDC" and "Ground" connections are designed to accept 4 AWG power wire. 2 AWG or 1/0 AWG pure copper wire is recommended for any power wire run longer than 72 inches (180 cm). This larger wire should be reduced to 4 AWG using a distribution block within 36 wire inches (90 cm) of the amplifier's "+12 VDC" connector. For runs shorter than 72 inches, 4 AWG pure copper power wire is acceptable

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!!
