Sure Electronics AA-AB33184 4x100W TDA7498 Class-D Amplifier Board

for the price, you can't go wrong! I bought two and made a 12 channel amp for under 250.00

worked great no problems drives 2 subs and 2 full range speakers

So much fun and great clarity. I've used it in plenty of applications and it is exceptional. Very quiet and plenty of power!
