Review: Works great for my Goldwing with amp - Used this in my Goldwing to convert hi I put from stock amp to rca and then fed it to my amp in trunk. It’s palm sized and quality is good. Recommend for the price. Lot of instructions given, so very easy to install. Love it. Recommend to buy, amazing price. Put this cause my Goldwing stock amp hi level was too hot and this made it so much better
Review: A small, inexpensive converter that works well - I'm using this in an unconventional application: taking a shortwave radio speaker output and converting it to line level inputs to an audio equalizer. It's perfect for this and works like a charm. The price is cheaper than buying a single audio transformer, and the adjustable level on the converter is very convenient. I can't comment on how good it sounds in a car stereo application, but for a communications receiver it works perfectly.

## Questions & Answers

**Q: Will this work woth 2006 chrysler croosfire?**
A: It will work in any vehicle. What is more to the point is what application you have on mind.

A: Yes just make sure you get the polarity right

**Q: when they say 80 watts max per channel, are they refering to the output power of my factory radio? my amp puts out 125w x 4 RMS**
A: Factory radio but even tho your radio says 125 x 4 that is a max rated not a RMS rating so you will be fine

**Q: trying to install sound system (head unit, amp, subwoofers)to 2010 impala that has the stock Bose system. Will this be powerful enough to support that**
A: This item is meant to reduce the signal strength from your aftermarket head unit before it goes into the stock amp, in this case, your Bose stock amp.
If your intent is to continue using the Bose Amp to power your stock Bose speakers, this item does the job.

### ⭐⭐⭐⭐⭐ Very nice value for the money, the bass knob works very nice
*by J***E on October 18, 2020*

Got this installed in my 2008 Toyota Avalon XL after a painstaking process... And it sounds great! I'm using it to power a 750w amp and two 350w subs with my stock head unit. Note, Camrys of this generation have the same wiring colors. Didn't have to adjust the gains for my left or right channels, just tapped into the rear speakers (Left Rear - Yellow with Grey stripes (+) , Black with Grey stripes (-). Right rear - Red with Grey stripes (+), White with Grey stripes (-). I tapped into them on the seat belt column area. I suppose you could do it at the head unit, but I felt safer doing it behind the seatbelt column panel. You can tell they're the speaker wires because they're the only wires intertwined together. The rest of the wires on the harness are not. I used wire taps where you crimp two wires next to each other together with a piece of metal, so I didn't have to cut wires. To get the 12v constant, I simply crimped the wire to a 5A fused line, then crimped it to an extra wire, which I stuck into the "B+" input on my amp, joining it with the power line from the battery. For the ground I did the same thing, routed the wire to the GND input on my amp with the ground wire stuffed in there. The Remote wire actually works very well and for now, has not given me issues. I was relived to not have to route another remote wire from some electrical part of the car, and I could just crimp a wire onto the remote wire from the LOC and connect it to my amp. It only turns the amp on when the radio is on. Perfect. My only fear is if the LOC Remote wire circuit malfunctions for some reason and causes my amp to kill my battery or something. Maybe there's a protection built in for that. Didn't seem to work at first and I thought it might be defective, but I re-did a few connections and it worked! I noticed more bass immediately and knew it wasn't my interior speakers. I connected the bass control knob, which I routed through the interior panels and it works flawlessly! It has a very wide range and is quite sensitive, at least for my set up. Turning it all the way down will essentially turn your sub off, so that's nice for when you need to go incognito! Couldn't be any happier with this. I didn't want to mess around with an aftermarket headunit so I decided to save myself a lot of headache and money. This will do the trick as long as you can tap into the right and left positive and negatives. Of your speakers.
