https://www.yuan-jing.com/index.php?route=product/product/&product_id=455 Trying to workout if this board can power a 2ohm speaker or not? i assume not but if it can that would help a lot 🙂. Context: I have a Alpine Type-S SWS-12-D2 subwoofer, which i got 2rd hand, snag is, that it is a 2x coils of 2ohm. i think will have to buy a new amp board to power it fully :| Thanks muchly!
run the subs coils in series and you'll have a 4-ohm load for the amp. No that amp will not run 2-ohm load.
Hi, the data " 2 Ω " is not fully specified by you, as I see :
1 mono amplifier having an output of 200 W at 4 Ω
1 speaker with DVC, each coil is 2 Ω
So you can
1) wire the coils in paralle so Ztotal= 1 Ω, which is too low
2) wire them in series so Z=4 Ω and that might be ok
in series means that (---=black) goes to (+++=red) so you apply the signal to the(+++=red) of one winding and to the (---=black) of the other winding

thanks for the replys. yep, tested it with one 200w@4ohm amp with the speaker coils wired in series. it works but next is to buy a more powerful amp then arrrgh oh well.
i already have a little ne5532 subwoofer filter pre amp board 🙂 . Should i do that maths and work out the resistor to set the frequency limits or would it be alright to gently turn up the freq nob/VR until i reckon its reached its design limits?
So i’m thinking of getting a mono bridged tas5630. while they can do 600w half of that is at 10% thd 🙁 so i’m thinking of getting connexelectronic 200w stereo and using that in bridge mode. Which also means another ££ 12v dc to 45+/- duel dc boost converter! 🙂 http://connexelectronic.com/redirec...ic.com/documents/IRS2092_Stereo_Amplifier.pdf
note: that my aim is for this to be battery powered. im using a 20AH 4S lipo 10C. so these 48v and more amps are not a option as i dont want to have to buy/use more of batts and wire up to get enough power/volts. As theres limits to what boost converters can do, it seams. i have a sure 500w boost Sure Electronics' webstore 500W BOOST Converter for CAR Audio - TL494 which is the best dc-dc boost i can find. other ones can only do such voltages at lower currents. 500w really is the limit anyway. any more than that and weight and size of everything is a problem! -for a portable setup.-
