i suppose you are looking at this amp
https://www.lazada.com.my/products/tpa3116d...2981766493.html go to the datasheet at https://www.ti.com/product/TPA3116D2#produc...tails##features then you will see its 50+50W at 4ohm means ngam your application. they mix two channel to form 100W err what is a subwooffer speaker with dual voice coil?

https://manual.kenwood.com/en_contents/atta...load/1000005943 your amplifier price not bad. https://www.lazada.com.my/products/tpa3116-...1890454052.html from datasheet should best suited to 2ohm for the 100W max. https://www.ti.com/product/TPA3116D2#produc...ls##description so your choice of dual voice coil sub is correct. one subwoofer is sufficient.

QUOTE(vinothrao84 @ Jun 30 2020, 07:24 PM) Thanks for the helpful response bro. 2ohm means its easier to push, less resistance.But I'm little confused here. U mentioned 2 ohm. So that means i need to set subwoofer wiring as 2 ohm? Will the woofer wattage increase coz of 2ohm? And the 100w from the mini amp will output 2ohm or 4ohm? Thanks.  to get your full 100W, you need low ohm and high voltage. if you use the standard 12V, most likely you wont get full 100W. recommend to use 24vdc. |
