Any help or info will be appreciated as I am getting rid of my JL XD400/4. TIA.
What makes it worth $600 to you? (This is a serious question.)Where can you find a better amp that combines all of the same qualities for $600?
It combines all of the qualities I want in an amp. Tons of power and headroom, small enough to fit under the seats, class D efficiency, reliable and no speaker killing problems like turn-on pops, and non existant noise floor. You can literally crank the gains all the way and unless you have the engine off and your ear right next to the tweeter, it's silent. You also get technology not available in other class D amps. I believe JL owns the full range class D market. There are many amps that do not offer what these amps offer that cost much more. FWIW, I got mine for $500 authorized new.What makes it worth $600 to you? (This is a serious question.)
OP: What makes you dissatisfied with the XD and what do you expect the HD to give you that the XD won't? Is it just a question of power or is there something else?
Define value. If the XD can't supply enough power for my needs it doesn't matter how good the value is. I looked at the Rockford amps but they wouldn't fit under my seats.Plenty of amps that can do that.
The Arc KS 125.4 Mini is efficient - class GH - and has the other benefits you mentioned. The XXD series seemed to be disliked due to problems, and the replacement XDi is said to be fixed completely, but I'm right behind you in not trusting it.
The Kenwood XR-4S is good and isn't known to be problematic to my knowledge.
The PPI Phantom series just came out and seems good so far but I'd like to wait a bit before I consider buying it.
Rockford has Full-range Class D amps in all 3 lines now. I would never own their subs but their amps are great. The Prime series ones at least are reasonably small.
And I don't think the HD competes favorably over XD for value - not even close.
