JL Audio Slash Series 1V3 Amplifier Review

best car subwoofer

This amplifier originates from one of the company’s most legendary amplifier sets and were built upon the very platform that made history in the field of automotive amplification. This product truly encompasses some of the company’s latest technological and manufacturing materials. For instance, the moonblocks are approximately 20% more powerful than older amplifiers thanks to new Class D output circuitry. Furthermore, this amplifier, which is a total of four channels, offers the company’s Absolute Symmetry Class A/B output stage, which offers an output of 75Wx4. This product also contains the company’s Regulated Intelligent Power Supply technology, which helps to maintain a power output over many load impedances and battery voltages. This will automatically adjust to help maintain the rated output of the amplifier at all times regardless of either the input or the condition. Furthermore, the Advanced Rollback Thermal protection feature will ensure that your music will continue to play regardless of current climate conditions.

Bottom Line

JL Audio‘s Slash Series 1200/1v3 Amplifier is hands down one of the best amplifiers available in the market. The amplifier is extremely powerful and is capable of running any subwoofer on a great scope. We tested this amplifer with a customoized dual 12 inch w6v3 subwoofer and we were absolutely floored. The subwoofer also has a wide variaty of features that come in handy such a beingg able to dial in the Q on the subwoofer boost. The only drawback we could find with this amplifier is its price point and fairly large and bulky design. Put it simply, if you have the cash and you are looking for the best possible amplifier that money can buy, this amplifier is for you.
