JL Audio 1200/1

This high-powered icon has made its mark over a decade-long production run, thanks to its prodigious real-world power delivery, fidelity and ruggedness.

Efficient Class D technology with a patented control circuit and JL Audio's signature R.I.P.S. power supply design ensure full power delivery (1200 W) over a wide range of load impedances and vehicle voltages.

The 1200/1v3 also boasts a very complete set of signal processing features, including a parametric bass EQ and fully variable infrasonic filter.

This amplifier features an all-black look that is pure, sexy evil, including the powder-coated cast alloy heat sink and end caps.

    Greatest bass amp I've ever owned.

    Posted by Jus10 on 5th Sep 2015

    I bought this amp to push a JL Audio 13.5w7AE and I was not disappointed. This amp's power makes the sub not only loud, but the sound is rich and full of life. I am barely pushing the amp and it's almost too loud! I'm not sure if I am more in love with the 1200/1v3 or the sub, but either way it's a marriage made in heaven. I can have this amp bumpin' for hours and it never gets hot. I was expecting this huge amp to cause my headlights to dim, but it doesn't. Some cons are the price and the amp is also very big and heavy, which made installation more difficult. I firmly believe this amp was worth the extra cash and the added time to install properly. Creative was also awesome to work with. I have been buying from Creative for a while and I'll definitely be back.
