Hello sir MANOJ, Iam going to build ur "AUD250SF" amp. I prefer 250W @ 8ohm for sub woofer. sir i have some doubts on this..
1. Do i need to add lowpass filter to this amp for subwoofer.if no then what is the cutoff frequency.
2. can you provide PCB of Power Supply Unit & DC protection for this amp.
3. sir ,for this amp what will be the wattage of Subwoofer i would buy
i mean is Subwoofer below the amp rating or higher the amp rating.

hi Manoj sir, thank you sir for your replay.Oh yes, im from Trivandrum.sir sorry to ask again ,because iam not clear about some sections..
1. Selection of SubWoofer...i meant that, For this amplifier what will be the wattage rating for the Subwoofer. ie below 250w or higher than 250w.
Because iam newbie in selection of subwoofers.
2. For PSu, you mentioned aud600 psu. But its output is +/-75 so how toreduce to +/-45.
sorry for asking again..

New PCB(all SMD) is working good @300KHz FSW no heat and best sound quality.
Test mode
supply--- +/-65V DC
load---- 2.6 Ohm speaker ( 3x 8 Ohm)
without signal fsw=323KHz(323KHz first switch on then it reduced to 302Khz). with signal fsw=297Khz
FET used IRFP250N
start oscillating without signal.

I am starting a project with the TAS5630 can some one tell me which is a more effeiceint board the shure 2 x 300 Watt 4 Ohm Class D Audio Amplifier Board TAS5630 300W Stereo Power Amp | eBay
board or this one Assembled TAS5630 +OPA1632DR 300W+300W Stereo Class D Audio Power Amp Amplifier Board-in Amplifier from Electronics on Aliexpress.com
I already have the power supply do I need anything else Input Voltage: 100~120V AC, 200~220V AC (Preset 230V)
Output Voltage: 48V DC
Output Current: 7.5A
