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 HD750/1'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

Pretty freakin awesome!

The following review is for HD750/1, which is a part of the bundle you are viewing.

Bought this along with the JL Audio 12w7ae and had a custom enclosure built. This was installed in a 2012 Scion tC. Very clean sound and it hits super hard! Best setup I've ever owned. Sonic Electronics was super fast getting the sub and amp to me and at a much better price than anyone else! Highly recommend this setup. Even if you don't get JL, I would still recommend buying from Sonic!

I'm pushing a 12W6 with my 750/1 and I couldn't be happier. I should've purchased JL products a long time ago.

JL HD750/1 mono amp

The following review is for HD750/1, which is a part of the bundle you are viewing.

I have this amp connected to a JL 12w7 prowedge sealed box. it hits pretty good. I wish I would have saved a couple hundred more and baught the 1000/1v2. bottom line is this: if you have limited space and want a great amp then this is the way to go. If you have the room and want one of the best amps made, then buy the JL 1000/1v2 amp. it's an old school analog amp built to give real power. The HD series are digital and dont seem to have the umpff like the 1000/1v2 slash series. It matters what kind of sub you have too. I'm upgrading to a ported 12w7 HO box and the 1000/1v2 amp just cause i know it will sound better. Overall i'm happy, but you know how it is.

Awesome Amp

The following review is for HD750/1, which is a part of the bundle you are viewing.

This amp sounds so much cleaner than other avg quality amps. Very small, barely gets warm. I have it powering 2 JL 12w3 subs in a Sonic brand sealed box. Sounds very nice and clean. Great experience with Sonic on all purchases. Quick shipping, awesome customer service when needed. Keep up the great work Sonic!

Expensive, but great performance.

The following review is for HD750/1, which is a part of the bundle you are viewing.

Over all great product not sure if it's worth the price tag, but the performance is excellent and I guess that's hard to put a price on.

Clean Power

The following review is for HD750/1, which is a part of the bundle you are viewing.

Powering two 12TW3-D8’s in a JL Stealthbox under the backseat of a 2018 F-150. Plenty of power for the job. Seems to stay cool even after driving it hard for 45 minutes. Hard to beat JL quality.
