Great product!!!

The perfect item for anyone who want to add a subwoofer with amp to their cars/trucks stock radio/deck just by splicing into the high signal speaker wires...
And the best part is, the sound is clear and I can totally control the volume of my added subwoofer, independently, for all types of music.
Don't listen to all the hype about (you need a new aftermarket deck with low signal RCA outputs). My system sounds great for the cheapest price!!!!

Great value

This is the lowest price the I could find. And a good unit. Will buy again.

Nice RCA bass knob

Great value little RCA with volume control used as a line out to my sub woofer amp. The knob is a little wobbly on the end of the stalk so I gave 4 out of five stars. NO NOISE with the brown ground wires hooked up.

Excellent product

I would recommend this to my friends for the value and features.

Nice Control

Used with a Bazooka BTA850FH subwoofer install on a 2011 Ford Ranger XLT. I wanted to keep the stock head unit. However, it does not have subwoofer outputs. I used the hi/low line-level controller to tie into the head unit high level front speaker outputs and connected the subwoofer input to the low level output on the controller. I can independently control the volume level of the subwoofer. It works great. Installation requires knowledge and understanding of wiring and installation of electronic devices. I also replaced the stock speakers with Pioneer TS-A6874R 6x8" 3-Way speakers and installed a 150 Hz bass blocker at each speaker.
