I Dont recall and PG series amps with regulated power supplies. I believe that that is the power that amp delivers into 2 ohms, and for subs you could look at a MTX 7500 or 8500, You could look at a JL W3, you could look at eclipse alluminums, you can look at Boston Pro, this list is pretty much endless for good quality stuff. Do you have any local shops and if you do what do they sell. If we can recomend stuff sold locally then you can go and hear it first then decide for yourself.

I understand that a lot of them are moreless equally good, so I just want to see a list that will do me good and from there I will chose based on price and looks.

Ok, well price and looks are important, but they should always be 2nd and 3rd to sound. Don't buy anything without listening to it first.

Next, I went to PG's website and here's what it says on the variable load: It's not a regulated power suppy, but it does hold power over all loads.

XENON AMPLIFIER SPECS:
Xe.flow™ variable thermal feedback controlled fans
Xe.tune™ 24dB Linkwitz-Riley low pass and subsonic filter
Xe.load™ optimized for any impedance load

Hey guys,It's not the fact that it is a "stereo" or "mono" amp that gives you better power eff.It is what type of amplifier class you have.Class A/B is apporx 46% while Class D is 80%-90%.For your Import I'd look for a class D.No more that 500 watts or you will be needing an upgraded alternator.Try HiFonics.Good luck

I'll be buying everything off ebay, as I usually do. Already found that amp for like 220 USD, from the same seller who sold me the other PG amp. Shipping though is kind of a rip off...50 bux.
I think that Infinity amp looks pretty good. 350 watts and 94db sensitivity (10 inch) and 96db for a 12 inch. Probably will stick with a 10 inch...don't think these 2db would do much...besides, most of other subs are like in 83-87 db range.

Sorry, that is "Infinity sub", not amp.
Where is the edit button any way? ;)
One question about Infinity. Their frequency range is 18-150. Should I look for something higher than 150? That way I could crossover my rear speakers higher than 150 and eliminate all the rattling.

No not at all.  Chances are that the sub will be crossed over lower than 120hz.

Why would I wanna crossover it lower than 120hz? Would it blow by playing lets say something in between 200-500hz?

No the sub would not blow by playing at a fequency higher than 120hz. What it would do is take the sub out of the range of frequencies that it was designed to play at. Meaing it will be playing into the realm of midbass. What you hear is generally muddy sound in your bass response. By keeping the frequency range lower on this particular driver and restricting it's range of frequencies by using a crossover, the sub can do what it was designed to do, play sub bass, not midbass or midrange. While there may be applications where a sub like this is used as a midbass, this is not the case in your system.

Also, as the frequency creeps higher you'll start to localize the source easier.  You generally do not want to tell where the bass in a system is coming from if it is coming from somewhere other than your front stage.
