2 PCS Car High Frequency to Low Frequency Output Converter, Speaker Output to RCA Line Control Audio Signal Adapter, CD Player High and Low Modified Audio Wiring, Universal Car (Transparent)

These are not meant for high power!!!! I've found anything under 50 wrms connection to these are perfect. Anything over 50 watts it's a gamble. Results may very obviously, however if you're look for a non active converter for you home/car system to influence a sub or any amp this can be okay and is a short term remedy. Please be aware, these are good for lower wattage applications, these will leak mV to LF amplifier input if over powered!. With that, these will give you what you are looking for. Clean look, good sound( low wattage applications). The pots/ level adjustments, if they can be called that, are fairly touchy or completely dull in response.Honest opinion. Very good cheap, temporary hf to LF converter.Final Thoughts, be aware of over heating and over volting (will send car amps into protec mode, home plate amps will possibly burn LF input). Best in room temperature environment. Keep out of direct sun light . You get what you pay for. These seem to be rather good for being passive NOT active.

These converters work like a champ, use the for home or auto. The adjustability works great.I use these for adding a subwoofer to older stereo equipment.Great item.

It's all right

Got 2 but neither would work. Had to buy another one at a local place. IT WORKED OK.

My husband used this to set up my subwoofer in my Kia Rio. We needed this connector, and it worked perfectly. It’s easy to use and has simple connectivity. Durability seems good so far—haven’t had any issues yet after 2 weeks of use. The sound quality is great, and the bass is amazing in my tiny little car.

These are very well made. The signal is clean coming through. The connections are tight and the wiring is well made with quality materials. The wires are a bit thin so make sure they are used in the proper way to not cause any damage.

Wires are to thin
