yes the TXX-SPLs are dual 2s and in my avatar thats my 4 15" TXX-APX 3" coils, had one of these on them, then 2 of these on them, and then 2 GD6001s strapped on them, over 6kw, these AP3000.1s are the best amp for the money in my eyes, you wont get more power for the money, and everybody kinda laughed at me on here when i first got them...O you got audiopipe big deal, now you see lots of people with there amps. The amp will do a strong 3kw at 2ohms and is very effecient!
