I wanted to use car woofer as Home Hifi woofer and i wanted to get those 2.1 mini amplifier that can be found in Shopee. The sub output rated by the mini amp is 100w RMS. Not sure at what Ohm. It says able to support from 4ohm to 8ohm.
Question is, if i buy a car woofer that is rated at 300w RMS 4 ohm dual voice coil, does that mean if i connect the woofer to the amp via 8 ohm wiring, does the woofer cut in half power to 150w?
I mean can the 300w 4ohm DVC woofer connect to 100w amp via 8ohm woofer wiring?

Assume at 8 Ohm.
At 4 ohm, its gonna be about 50 - 70Wrms, assumming the RMS can be trusted =D
You just need to match you subwoofer power with the amp. If your amp is more power than subwoofer. The sound will be distorted.
The amp is rated 100w output and the woofer rated around 300w for 4ohm DVC. Do u think the amp can push the woofer? Should it be wiring at 8ohm or 2ohm?

so your choice of dual voice coil sub is correct. one subwoofer is sufficient.
Thanks for the helpful response bro.
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?

2ohm means its easier to push, less resistance. 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.

I just purchased 24v 5a adapter. But I'm just wondering, the sub output is max 100w at 4ohm. So if i wired the woofer at 2ohm, then the woofer surely needs more than 100w right? Please correct me if I'm wrong.

Sub.. 300w RMS @ 4 Ohm DVC mean 150w RMS @ 4 Ohm for each VC.. Amp.. Max 100w RMS @ 4 Ohm equal to 50w RMS @ 8 Ohm.. if output rate 4 Ohm to 8 Ohm mean not stable to run below 4 Ohm..
Based on the above Sub Spec.. You required 600w RMS @ 4 Ohm amp or stable amp can run 300w RMS @ 2 Ohm.. Coz what ever wiring you use, sub pwr still maintain @ 150w RMS per VC either run at 2 or 8 Ohm.. Only amp pwr output can be increased or decreased depend wiring..
