You need more power for the subs. Should be looking at a 4ch and a mono block if you want to use those subs...
t1000x5ab smaller constant power built in fans (it really needs the fans) you would need to run a 4 awg wire from the battery to a distribution block then 8 awg into the amp or find a reducer that'll work. Same for the ground.I have 2 of those amps.
Things I like, the size, it's a constant power amp, clip light,attenuation knob, it has a switch you turn off the sub amp if you decide to add a more powerful sub amp.
Things I don't like, it runs hot (maybe didn't need it but I added a external fan it runs hot enough without the added fan you can't put your hand on it and leave it there with the added fan it runs more like most amplifiers) the quick release terminals. Power and ground right next to each other. It's so small so the terminals are a compromise but they could have put the remote turn on in between the power and ground. You have to buy the attenuation knob.
I did have to send one back for warranty repair sub amp went out but it only took 2 weeks from time it left my house to when i got it back. That happened after only using for a few weeks. The other one i have is over 2 years old no issues. If i was going to do it again, for my set up in my honda,id probably go with the t400 and t750 takes up about the same space more sub power not too much diff in price.
