The rs have 2 inch voice coils. Don't run more then 600 clean watts. My 4th gens are 2.5 and can take a little more
Look at the online manual for this deck on alpine.com, more like 18-21w RMS per channel, as with 99% of decks out there. You won't find a 45w per channel RMS deck under a grand. Still be a huge step up from what he's running, but don't give him false hopes:nerd:Alpine and you can get the 45rms x 4 power pack to run your highs

Oh yea, I really didn't pay much attention sorry. Those are legit. Lots of people are under the impression that a 50x4w deck means a 200w deck though, it really means 50-60w RMS and 200w at perfect condition peak. The only way to get decent wattage to the front stage is that power pack or a mids/highs ampThe power pack is 45rms not the deck. It plugs in between the deck and wiring harness and sits in your dash. I got one so I know
Your comparing a $120 power pack to a PDX?Do not get the power pack. I have an alpine cda-105, started with type r components in front and type r coaxials in back wired directly to head unit, sounded like @ss. Bought the power pack, got a little more volume but sounded like ***, you will not be happy. I got a 4 channel alpine PDX feeding my highs 100 watts rms, they sound super clean and scream trebble, I had to set my tweeters to -4db. Spend an extra 50 for a real4 channel amp, plus your mid on your component will need crossovered if u want it loud, they crossover that comes with them is set to low and it will distort before you get good volume from your component set, power pack doesn't give you this option
Sry to say but there is a lot more than just 3 manf that produce quality HU's..A good head unit will say one of these 3 things somewhere on the front, alpine Kenwood or pioneer. Look at each of the companies websites and find a model towards the upper half of there line up at least
