Phoenix Gold Phorum

On soundbuggy I was asking a question about using an RsD500.4 at two ohms all around in the next car I will be picking up in a few months. Two pairs of RsD comps running off of the front two channels giving me somewhere around 230 to 270 total watts for my front stage, and bridging the rear two channels and running 230 to 270 to an RsD 10 or 12.

After thinking about it for a couple days, I was starting to think I might want more watts for the sub. I may end up running 1 Ti elite 12 or still 1 RsD 12 or 10. I can only use 1 amp because that is all I am going to let myself do this time around since my next car needs to be an everyday driver. 1 sub would take up that much less room, so I am favoring 1 sub.

I am not sure the wattage an rsd500.4 puts out can quite cut it for what I have decided I will need of course...I mean I know it can't for the elite. I did, however, stumble on the memphis mch1300 amp. Now I love PG but I am considering doing this memphis amp with all PG RsD components for my front stage, probably leaving them at 4 ohm to give me 75 to each set, and using the 5th channel of this amp, around 600 watts at 2 ohms, or 1100 watts at 1 ohm for the sub.

Since I cannot run the elite 12 properly with this amp, because 600 won't cut it and 1100 isn't possible with dual 4 ohm coils on the elite with this amp, do you guys think I can safely give 600 watts to a single RsD 12 or 10? Do you guys think the 230 to 270 watts I can give a single RsD with an RsD500.4 would be better than possibly overpowering and blowing the sub with that 5th channle of the memphis?

Has anyone tried this memphis amp out? Is it as good as it seems to be? I have all PG amps in my current car and I love them, but I just want to make sure I am happy with my power in my upcoming car because I can't have it turning into the car I have now : ). Let me know how you feel. Thanks.

well the ti elite is actually closer to dual 3.4ohm, so your final load would be about 1.7ohm or about that.

my RSD 12 took the full power of a xenon 1200.1.................daily and had no problems taking it, so itt'll take it without a problem


FYI the RSD 10 and 12 have the same motor just different size cone on it

Holy s***, that thing took 1200 watts...that's crazy. Single RsD 12 it is then : )...so the amp situation, anyone ever use the memphis belle? I used a 4 channel memphis before I even got into PG years ago, and I liked it a lot, but PG quickly overtook as my fav...but since the wattage will be an issue using PG in my application, what do u all think of memphis...and don't hold back, if u think it is crap, I want to know why, if u think it is great, let me know, I am not familiar enough with memphis to argue so I would love to hear critics respond on both sides...thanks a bunch.

Also at 4 ohms I need to correct myself, the memphis only does 55x4. If I ran the memphis belle, I would run 55x4 all to the front stage(2 RsD comp sets), and 600x1 to the sub. Does 55 sound like enough for each single tweeter and midrange set? It would give me a total of 110 watts on each side of the front stage. I know what the RsD components are rated to take, as little as 5 watts, but I know that is often not realistic. What are the feelings about the wattage that will make these components sound the best?

well we ran a sundownz 1500 amp to a rsd 12
so i would say at least 1k and it took it no prob...

ran a ms2250ta to one @ 2 ohms...thus around 1500 watts took it fine.


TOmmorow gonna try it ported

And we are still talking about the standard RsD 12? Not the competiton grade right, cuz that didn't get released yet...so are the feelings that 600 would be too little?

even us enthusiasts have yet to get our hands on a RSDc (although i did get to see one in the flesh on Monday)

the rsd svc i used off a xenon 600.1 did 137 in a 1.7 sealed box. so 600 watts will power it more than just fine. although....nothing wrong with a little "extra headroom"!

I ran an RSd10d at 2 ohms in a obnoxiously low tuned oversized ported enclosure with no subsonic filter with a T1200.1 scoped with no clipping at about 2.2kw for two months trying to break it.

I run an RSd12 currently in a 2.1 cuft enclosure with about 800 watts to it. It has lovely low end response and hits with serious impact.

Anyone out there giving an RsD around 250 watts? How does it sound at that level? I am just considering all of my options but it sounds to me like good wattage for an RsD should be at least 500 to sound decent.

They do superb even with low power as they are very efficient, make certain you do not adjust it to distortion and you should be very happy.

So perhaps initially, I can still use an RsD 500.4 the way I was thinking with the 2 pairs of components off the front channels and sub off the rears. That would give me around 250 to 268 bridged 2 ohm for the sub. Then when I want more power, I could always upgrade. Buying a 500.4 would be cheaper for me than the memphis belle of course.

If I do not adjust them to distotrtion, do you mean I should adjust them by the ac voltage equation, since I don't have an oscilliscope or anything.

You can use the AC equation and finish it off by ear. Also you really will not want to run a 2 ohm mono load on that amp unless you want it to be a space heater.

ha...good point, my bad..i will probably wait for a good deal on this memphis, i have a little while before I get the car anyway.

Anyone have any opinions on the Memphis Belle Amp? Is the newer one the same amp ans the older with a new exterior?

Hey everyone, I just stumbled on an older thread on Soundbuggy regarding the xs6600. This is an older 6 channel PG amp. Anyone know much about it?

The power ratings I am finding are:
4 ohm stereo @ 12/13.8 VDC: 18/50 WRMS x 4
2 ohm stereo @ 13.8 VDC: 90 WRMS x 4
4 ohm bridged @ 13.8 VDC: 180 WRMS x 2
Subwoofer Channel Output Power:
4 ohm stereo @ 12/13.8 VDC: 25/75 WRMS x 2
2 ohm stereo @ 13.8 VDC: 150 WRMS x 2
4 ohm bridged @ 13.8 VDC: 300 WRMS x 1

Is that rms 18 and max 50? How is the quality on these old amps? I would be running 2 sets of components for my front stage...but those ratings look like they might be a little low for RsD components. If the best I can do is run 2 ohm stereo on the front channels, 45 to each tweeter and midrange set might not cut it. A minimum of 18x4 with a maximum of 50x4 in 4 ohm stereo also may not be worth it. Would I even see that 50x4?

Anyone have any opinions on the Kicker ZX 700, Hifonics Zeus, Memphis Belle, or Boston GT-50 5-ch amps? Opinions on any of these vs the xs6600?

Let me know, Thanks in advance.

the xs6600 is a solid amp, its essentially a xs4300 and xs 2300 in one heat-sink.

the 12volt number is only there to allow this amp to sneak into competitions. with your car on your system will(should) charge at 13.8 volts.

the cheapest i have seen this amp go for is about 250


if it were me, i would find a xs4600, a xs2300 (or 2500) for less money and run a pair of amps

4600=75x4 fronts - ~$110
2300=300x1 sub - ~60
dist block and accessories - $50

The lower ratings are 12 volt (IASCA?) ratings. The amp makes at LEAST 50.

If your referring to their (Memphis) class D stuff, well its the same as it always was (made in China) and the exact same guts as Directed, Orion, PPI, Kicker, JBL BP series, oh and MOMO. They are all clones of the sames design, using the exact same parts, and even the same green circuit board. All clones, nothing new, same B52 & F16 chipset in the D section as all the other amps listed above. So if it was me I would keep looking for something more original, perhaps Phoenix Gold

I am curious how the xs series is with heat management. Does it overheat easily?

How does the Crossfire vr705d compare to the PG xs6600? Anyone seen any Ti900.7s lately?

I am running 1 set of RSd65cs up front in stock locations. This will be powered with a Ti600.2. If I highpass those at about 40Hz where bdubs said he felt they would comfortably play loud in his review, I should be good to go right? The passive would take care of the rest.

Question:What would be the benefit of running these components in an active crossover setup? I hear a lot of you talking about running comps active, is the passive really that much worse?

In my current car I run my elite mids and tweets passive and my midbass 9m drivers active and it sounds great. What am I missing by not running everything active?

I keep using my older threads because I don't want to pollute the forum too much in case you guys were wondering .

I will be running 1 set of RSd65cs up front in stock locations in my Golf which are on order. This will be powered by a Ti600.2. If I highpass those at about 40Hz on the amp where bdubs said he felt these comps would comfortably play loud in his review, I should be good to go right? The passive would take care of the rest.

What would be the benefit of running these components in an all active crossover setup? I hear a lot of you talking about running comps active, is the passive really that much worse?

In my current car I run my elite mids and tweets passive through the included xover and my midbass 9m drivers actively bandpassed between 2 amps using the aux signal output of a ti500.4, low passed at like 150, and the 9m s themselves are powered with a Ti600.2 highpassed at about 60. That is considered active for the 9m right?

What am I missing by not running everything active?

No active is not better then passive....

Well kinda I guess but not really.


W/ passive set up your stuck w/ xover points, w/o ta between mid and tweet.

When it comes to installing things active will allow for a much more flexible install. You can for ex. place tweeters in pillars, mids in doors and have the ability to play around w/ xover points and ta to get the speakers to blend better then if you were stuck w/ the given passive settings.

All cars are different and all speakers perform differently in every car...thus why active is so highly recommend in a car because it allows you the ability to tune in every way for your specific car.


But IMO, if you are to mount a 2-way comp set in kicks w/ a passive on the same plain, and have TA from R/L there is no real benefit over a two way run active.


But if you cross over into the 3-way you IMO will def need to at least run some part of the set active.

Yeah it makes a lot of sense from the time alignment perspective.

I will have the midrange in my door by my feet and the tweeters way up on the dash...

Which speaker do I time align to since I am running them passive?

Maybe I should have gotten a 500.4 instead of a 600.2...maybe is till will...
