So you want 2 250$ amps that will put out 400 watts into 4 ohms each that are class A/B for subs.

When you could get an amp that put out the same power at that impedance for 200$ and it's a class D with an added bonus that you can get different coil configuration later and use 1200 watts @ 1 ohm???

I hope you know the difference between different classes of amps.

Hmm lets look at othe differences. Mine has a 24db/oct crossover/ sony has a 12db/oct. Mine has a 24db/oct subsonic filter/sony does not. Mine has a remote bass controller/sony does not. Mine has preamp outputs/sony does not. Mine.... Nevermind hopefully you got it by now.

I'm not shooting smoke out of my @ss., I know what I am talking about when I say it is a better amp. But if you really don't want it thats fine, I'll respect that. I would just rather see audio enthusiast get good equiptment.

i can say that there is nothing wrong with x's 1200 i was at the last show he was at and it worked fine for him there and am pretty sure he took it out after that show was done to make room for his new product

for your situation i would recommend a 2 channel amp running at 4ohms mono. Mono block amps are set up to run 2ohm loads, which you won't be able to run with your current sub setup.
If you go back to the Future Shop I would go with the Rockford 401s (399.99--400watts bridged at 4ohms, remote bass ****)or the MTX 282 (299.99--280watts bridged at 4ohms) Sony Xplod for the most part is pure death-the stuff is called explode for a reason. Remember a good amp is going to cost you about a buck a watt--if something sounds too good to be true it probably is.

Frivolous options. Most of those really don't reflect the amplifiers' class, nor make an amp much better. Just flexibility is increased with more of those options.
None of the amps I'm going to use have any of that garbage on them. But of course I'll be using an active crossover setup on the system.

12db/octave is fine for bass. If your deck has a low pass sub filter, use it. If not, make sure that the amp has at least a low pass crossover. Selectable or variable crossover points help, too.

It more or less also comes down to what you want to spend. The Sony XM 2165GTX is a good deal, and will work with your setup if you load it down to 4 ohms mono.

my local shop is offering me the Audiobahn A8000T Link for $500 with taxes and sound domain is offering it at $531.08 CND after taxes ($462.44 without taxes). what do you guys think (I'm sorry Xiph0id but I just not ready to buy used again after being screwed man but it is a sweet deal.)

Sony amps IMO produce cleaner power than the dirt Audiobahns. No amount of chrome can cover up a dirty amp. [img]smile.gif[/img]

i jsut dont see why you would buy a 2 channel for subs. a/b amps draw more current, and most out there arnt even 2 ohm mono stable which means you dont ahve many options when it comes to upgrade. buy a nice mono amp that will do aprox 1000 rms at 1 ohm and youll enver need to buy another sub amp again. my first sub amp i bought was a 2 channel and ill never buy another one for my sub again.

class d mono block = more power, more options , less current draw.

that sony says 400 rms bridged right , well tahst at 4 ohms, what happend if you go buy 2 4 ohm svc subs ?? you wont beable to use that amp anymore cause it isnt 2 ohm mono stable. and all you gettin gis 400 watts. where as for example a jbl 1200. puts out 1200 at 1 ohm , 600 at 2 or 300 at 4, so you have much more options down teh road.

Not necessarily. I certainly wouldn't pay $400 for a 401S when I can pick up an older RF 360.2 or Kicker ZR360 for like $350-$400 and they're built much better and produce a hell of a lot more power (Well into the 500s) than the barely underrated stuff RF is spewing out lately (at least the Punch series). Plus, do you really want an amplifier that says "1200 watts max" on the front ?

No, the JBL BP1200.1 produces 1200 @ 1 ohm, 1200 @ 2 ohms, and 600 @ 4 ohms.
The only thing true about that is the less current draw (in comparison to a typical class A/B amplifier). More power for the price maybe when you get into higher powered amplifiers. More options isn't related to class at all ...

well more options as in its alot easier to find a mono amp tahts 1 ohm mono stable then it is a class a/b amp. [img]graemlins/thumb.gif[/img]

Fair enough for me. I wish you luck in your subwoofer amp search. [img]graemlins/thumb.gif[/img]
