Amp and subs problems

[Joebro63]

I just upgraded my system from a class ab 4ch 160wrmsx2 and one 150wrms sub and one 250wrms sub to two brand new 250wrms subs and a d-class 4ch 440wrmsx2 @ 4 ohms bridged I also upgraded my wire from 8 to 4awg

But here's the problem. The subs won't crank out sound nearly as hard as the old gear. And when I get the gains near max the voice coils over heat and start to stink. Part numbers are fusion ca-da41400 and en-sw120(x2) kit is fusion 4ga (recommended with amp)

Can anyone help please? This has cost me 100% of my earnings already

the subs are rated 150rms and how to you got it hook to the amp you have to bridge it on the fr+ fl- on one sub and the other sub to rr+ rl-

is the box different.

what else is different besides the wiring, woofers, and amp.

did any of the headunit settings change?

if you took the - terminal, off the battery, the headunit would have reset back to factory settings

[Joebro63]

Na same box, I have tuned all the head unit settings, it has three band parametric ieq and I've got it all the same as it was

[Joebro63]

And the subs are en-sw121 not 120

i assume each sub is wired to 2 bridged channels of that 4 channel?

[Joebro63]

Yeah

[Joebro63]

On the old amp I had the old subs wired in parallel off the rear bridge
