HELP: Budget sub amp

Centvrion · 16th May 2011, 05:51 PM

HELP FOLKS!
I need a pre-soldered kit (or even a car-audio ready-to-use) -possibly class d- amplifier to power my two subwoofers, I will make by myself the (active) low pass filter.
Maximum budget for amp module and PSU=40€ (about 60$), shipping and taxes included.
I have to power a pair of 4ohm 40W ("nominal") 6,5" sub in t-line (tuned at 40Hz), don't know about their efficiency, but I need no more than about 15W (or a bit less) of "undistorded" power.

Can someone give me some advice?

Not sure if its going in car or a house, but ebay a ta2020 amp should fit the bill.

Thank you nightanole :-), umm...TA2020...that's what I was looking for!
It's for home use:-)

Is there any cheaper module? (I have to add 25% taxes because in Italy it's pretty difficult to ship with ordinary shipping - it will take between 4 and 6 weeks :-!!!, and express' rarely permit to value the pack as "gift", moreover express costs a bit more)

Is there any other idea in order to have a bit wider choice?

Like i said look for something with the ta2020 chip in it.

Id try to get one from HLLY if you want name brand china with a case.

If you want alittle cheaper you can try this
MKll Tripath TA2024 fully finished&tested pcb 2x15watt | eBay

Its a ta2024 so its 15 watt x2 instead of 20watt.
