  Some of you have noticed the poor sound from my mic. I had an issue with the mic that I noticed only in the post. Apologies for that.

  Just picked up a Fosi Audio BT30D Pro 2.1. Used some stuff i had laying around-mid 90s JVC bookshelf speakers and a JL Audio 10W1v3-4 in a sealed box. &nbsp;For a $100 amp I have to say I am surprised. &nbsp;This setup definitely punches above its price bracket. . Fosi said the internal Bluetooth module does not have the voltage to send a full signal to the Texas instrument chips. So I purchased a inexpensive (UGREEN) Bluetooth 5.0 Hi-res receiver. &nbsp;That actually helped the Sound a lot by bypassing the internal Bluetooth device it comes with.<br><br>Thanks for the review. I have something to listen to in the garage while working on my car audio system.

  I tip my monoblocks up on edge for better convection cooling.<br>It works really well.

  I have a very, very similar Chinese company amp driving a pair of full range three way high sensitivity low power demand DIY speakers. Each speaker has a 6.5” low profile 2ohm sub (42-110 hz) , a 4ohm mid driver (110-3200), and 4ohm tweeter I can cross at 3k. The passive sub terminals for the sub drivers (wired in series); then the speaker out terminals to the mid driver and tweeters (in parallel). &nbsp;Sounds great and was very low cost. &nbsp;The amp I chose is the same price range as the Fosi and love its ability to drive the two subs in 4ohm total) no problem…..and the mid/tweeter in 4ohm (wired in parallel). Love it.

  I had 32v adaptor model, now upgraded the power adaptor to 48v, much improvement in the subwoofer output on lower volumes.. I use it with Micca MB42xg2 and a 300w 10inch generic subwoofer.. It is a beast. Only thing is that , it heats up on 48v, have to use some heatsinks to cool it down..

  All the Fosi TPA3255 Chip amps are great. I have 2 Fosi ZA3&apos;s that sound just as good as my Bryston and McIntosh amps

  You can absolutely use an external Bluetooth device (like a high-quality Bluetooth receiver, a streaming dock, or a DAC with Bluetooth) instead of the amplifier&apos;s built-in receiver. To bypass the built-in Bluetooth on the Fosi Audio BT30D Pro, you will physically connect your external device using the RCA inputs on the back of the amp. &nbsp;Best to buy AIYIMA B07 &nbsp;is way better.
