Line Driver Specifications

Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
10 - 30,000 Hz
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

Why did you choose this?
Sonic Electronix Store
Used before and enjoyed what the product had to offer
Everett F on Apr 14, 2017
I wanted a good quality adjustment knob to control the level of my subwoofer channel. This one is a name brand and it got good reviews. Sonic Electronics had the same price as other retailers and since I have had good experiences with Sonic Electronics, I bought it here.

Best bass knob out
Justin P on Jan 31, 2017
question 1: is this powered by a 12v battery, i.e., can I use it in an RV?

question 2: where is the volume control?
Randolph H on May 23, 2016
Best Answer: Yes, it is powered by 12v DC, so it can be used in your RV as long as it is 12v. The volume control is a separate small knob that can be located anywhere you'd like, it connects with a cord to the main unit..
