subwoofer amp

sidd_raj2002 · 16th January 2005, 05:24 PM

heloo i am new to diy.

can any one please send me a schematic and pcb layout for a cheap,easy but reliable subwoofer amplifier to drive two subwoofers i built with a pair of local drivers (6ohms each connected in parallel)

it should be atleast 30-80 watts and mono with built in low pass.

in short should be ideal 4 a sub.

but please remember i am 17 yrs old so dont send something expensive and complicated with 2-3 pcbs at a time.

keep it as simple as possible.

I plan on trying this in the future... looks like you can make as much power into any load you want..very scalable. It's not the simplest but I'd bet if you I/you got the hang of it, I/you could build an ideal sub/hi pwr amp for any occasion.

N-Channel mosfet amplifier schematic needed

The citation 12 circuits are pretty simple too....

edit..
oops, no low pass on either...

Hi!
If you dont need such a HIGH power amp then use a chipamp!
like: LM3886, OPA541, OPA549, thay deliver between 20-80 watt, you can get free samples of these chips from:
www.national.com -LM38XX
www.ti.com -OPA5XX

circuits can de found on the web, also circuits for low-pass filter.
if you still need help or a circuit then drop me an E-mail!
