I have a Palomar 400 with 4X1446s and a DX500v with 4 DEI 2879s......in the same truck with the same setup, I get about 65 more watts with the Texas Star than with the palomar... 415 with the TS and 350 with the Palomar. Audio is said to be equal-ish. As said before, if you have an option, 4X1446 is a far better choice IMHO. I have no complaints with the DEIs I'm running, but I'm just talking, not beating the @#%$ out of them, in which case they'd explode into a cloud of magic smoke. HGs are good but there is not a pill made today that will take the abuse the Toshibas did/will.
