Trying to put together my next stereo system and I am at a cross road on which amp I like better. I have it narrowed down to 3 amps, Polk PA-D, Alpine PDX and the Arc Audio XDI. I have picked these 3 amps not based on sound but by specs. Anyone running any of these amps. I will be running 4 pair of the JL 7.7 & 2 10" Alpine R subs.
I think......

I sell Alpine and Arc Audio. We've been VERY impressed with the Arc amps up to this point. The XDi is a great price point, and powerful.

Wet Sounds Hydro-Tech line is another one we sell, and sell a lot of.

you could run all those speakers off of one Wet Sounds SD6, and if you have the space put the JL8.8's they are a huge improvement over the 7.7's

THe SD6 would be great, but he mentioned entry-level amps, and the SD6 is far from that.

The XS-808 and XS-650 (in my book) are a better buy then the JL Audio speakers. Same or better quality, they just don't the hype that JL Audio does. There are a lot more options out there that are better than JL.

Never looked at the Wet Sounds before, holy crap they have some powerful amps.

I really like the Wetsounds amps but they are not built anywhere near as well as the JL products same for the speakers. If you don't boat in the salt then it doesn't matter but if you do nothing is better than JL. I have replaced two M600/6 with two SD6 amps and added some speakers to handle the additional power but if you take both apart the difference in quality is clear. I realize the SD6 is not entry level but neither is a 47 Lightning, and to only have one amp instead of two or three is much better.

yes that is why I switched, follow my advice you won't be sorry.

I have done several installs with the Alpine and they have been great. Sorry no experience with the others.

The only bad thing about Alpine is I would need 4 amps to do what I want and they don't have audio out ports.

Very hard to beat JL Audio.
