This is a great amp for the money. I have it hooked up to two infinity kappa perfects. They pound pretty hard. Harder than my pioneer 820w and half the size. It gets slightly warm after beating for 10 mins and just as warm after like 6 hours lol. Doesn't get hot!! A buddy recommended Sonic to me and i told another friend about Sonic and he bought two alpine type r and a re amp and wiring kit. Im planning on buying a touchscreen dvd too! Cant beat Sonic's prices!! Thanks sonic :-)
