Product Details

BOSS B65N Speaker Level to Line Level Output Converter

The adjustable B65N two-channel speaker-level to line-level converter (also called a high-to-low adapter), from BOSS, allows for the installation of line-level mobile audio electronics, such as amplifiers and active crossovers, into systems without a line-level signal by using the head unit's speaker output.

Great for adding powered subwoofers to OEM systems. Input sensitivity adjustments allow for fine-tuning the signals sent to amplifiers to prevent amplifier clipping and maximize amplifier output. Built-on mounting tabs facilitate permanent installation. Dimensions (L x W x H): 3.4" x 1.5" x 1.5".

BOSS B65N Speaker Level to Line Level Output Converter
BOSS B65N Speaker Level to Line Level Output Converter is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Works fineYeah it’s plastic, yeah it’s a bit hard to reach inside and adjust the attenuators – but it worked out just fine. Hooked up in parallel with my rears to enable an RCA for my Sub Amp inputs. – The amp had speaker level BUT I needed to add a pair of FMOD inline Low-Pass filters. All worked just fine.

The color code chart for the input leads list both left and right as gray, but in the picture, I see green input wires. Which channel are the greens?

Asked by: Hifi_Tweeter
The left channel is green and green/white, the right channel is grey and grey/white. The conductor with the white strip is negative on both.
