Review: Is really good for the price. Bluetooth connects perfectly every time. Never have an issue. Note this amplifier is not meant for subwoofers nor is it meant to supply a lot of bass. I see reviewers commenting on those 2 topics but as said it is not meant for deep bass this is meant for high or all pass for door speakers for quality sound. Super simple to install and setup if you know how to tune. Gain shouldn’t be any higher than half way unless you’re using a very old head unit. I’ve used this amp in multiple vehicles including motorcycles, ATV, golf carts and classic cars where the owner does not want to modify the factory audio. And it has worked for me flawlessly every time using Bluetooth or rca. Build quality is much better than I expected originally. Only supplies average 100w rms per channel but that’s perfect for most builds. This keeps it simple to have Bluetooth built in. I have found that the lil antenna does come loose so I’ve been using a drop or 2 of blue loctite and hand tighten seems to have fixed that issue. Bluetooth doesn’t reach too far but I’d say a good 10-15 feet which is plenty. Wattage rating are very overshot this is not near 1600watts that it claims. Dynoed at about 600 max and about 300w max rms bridged. Most door speakers can’t handle more than 60-75w rms so it’s not a deal breaker for me just a bit annoying that they advertise a lot more than it really is. But again for the price really can’t go wrong
Review: Really impressed with this little unit so far! Just hooked it up in my teenager’s first car. Hand me down 2006 Corolla from his grandad. Didn’t want to throw a ton of money into a stereo system for the little old jalopy. Fun project to put new speakers and then run the stock unit through the amp. He will never use the radio, just run Bluetooth from his phone. Took a little wrangling to get it all wired properly. No real instruction included, but YouTube is our friend. The sound and power boost is really really good for what he needs. He is tickled pink! You need to disconnect Bluetooth from the phone to allow the original radio to pass through the amp, but once you figure it out it works pretty slick. I’m not tech savvy enough to know if it delivers exactly what it claims, but it sounds fantastic to us. Everything hidden away, so just looks like stock 16 year old system. Super happy so far, but it has just been a day!

## Questions & Answers

**Q: How can bluetooth be disabled on the amp? Even if I remove the antenna it is still active.**
A: There is no way to disable it. It has no interface that would allow this.

**Q: Using on 80's cars where customer wants to keep factory look,hide the amp in  dash, would you guys recommend small ball bearing pc fan on the end?**
A: I did this exact thing with this amp.  I have a 1987 olds toronado. I took the non working radio apart and mounted this behind the original radio face. Connected using adapter to original harness with zero cuts into factory harness.  It connects automatically to my phone and I just control volume from my phone.

**Q: What are the measurement dimensions?**
A: 6.7" x 3.8" x 1.8

**Q: i connected the power to the positive and ground to the frame but still not working.  Do I need to connect the Remote (rem) to something?  Thanks**
A: Yes, remote needs to connect to 12v (key switch is redommended) . Remote power functions as an on/off button and if always connected to 12v it Will drain youre battery.
