New Alpine amps

Hello, and greetings from Norway! :)

I like the amps Alpine produce, I currently use MRP-F200 to the front and MRP-M650 to my JL W6.
But I'm thinking about an upgrade. What do you guys think of Alpine's PDX amps? A nice upgrade?
I'm thinking about 4.100 or 4.150 to my SR5250's, and go active with my HU (Alpine CDA-9855r),
and buy either 1.600 or 1.1000 to the 12w6v2 subwoofer. Then I'll have everything I need...

What you guys think? I can get the PDX 4.150 half off here,
so I think I'll go for that one and use all channels on the SR's.
Anyone here's thinking "overkill"? And should I go for PDX 1.1000,
instead of the 1.600? Or is this overkill too? The JL handles 600w rms...

Best regards. :)

    If you're bridging the front and rears of the f200, then the sr 5250 are getting 100 watts each. The 100watts are being shared between the mid bass and the tweeter.

    If you bi-amp off the pdx 4.150, each driver would get 150 watts. This would also allow you to go active since your hu supports an active 2 way network. So yes going active would be much better.

    The amp on the sub is fine. I would'nt go for the pdx 1.1000. Instaed I'd spend that money on damping or look at a processor to complete the sound chain.

    Thats my $ 0.02

    I know about the bridging, that's what I'm doing now.
    It works fine with the passive crossover without bi-amp.

    So you think I just should use my old MRP mono-amp?
    Already damped a lot, especially on the front doors! ;) Teasers:

    what about the floor well? you would get a lot of road noise from there. Plus a processor will improve your sound much more than 300 extra watts on your sub.

    Bi-amping and going active will give you better control over each driver and it will allow you to play with the xover points.

    Thank you for replies. I haven't taken the floor yet,
    I am planning to take the floor and roof this summer. ;)
    I've damped the trunk well though, and above the wheels...

    Yeah, it's mainly because I'm gonna go active I am planning on getting a new amp. Wouldn't the PDX 4.150 work well? My MRP-F200 only produce 4x 40w rms - it's enough for the tweeters I guess, but it's just not enough for the woofers...?

    Seems like you have a fair bit done already. Though you can never have enough.

    the 4.150 would be very nice and yes 40x4 would be a drop in db's and sq from where you are.

    I know. But I'm pretty done with my doors for a while,
    they're damped a lot! Many layers on both inner and
    outer wall of the door, and even on the door panel. ;)

    ^ This was mostly to avoid vibrating noise...

    Yeah, I think I'll go for that one. But I should set the gains low, at least for the tweeters? I mean, 2x 150w for two tiny tweets? :D The set is rated to 2x 100w RMS, but do you (or anyone, Mac?) know how much of it that goes to the woofers?

    Oh my... I just found out the dimensions of the PDX-amps, and WOW, they're incredibly small! :D

    I have a PDX-100.4 and the 1000.1 both extremely well built and the SQ is amazing on them. I'm kinda interested in seeing what the new PDX amps sound like tho :)

    I have decided, I'll go for the PDX 4.150! :cool: I think I'll wait with the PDX 1.600/1000 'till I've got enough money.
    But will I notice any difference? How's these PDX amps compared to the ones I've got now? My current amps:

    MRP-F200
    MRP-M650

    Amps don't sound different. Speakers do.

    A watt is a watt. More watts is louder and 100watts to a 125watts driver is better than 40 watts to the same driver. But I doubt that you'd hear a difference between a 4x90 watts polk amp vs a 4x100watts pdx. As long as the amp has a low noise floor, doesn't induce noise and makes rated watts, its fine.

    Okey then. :) At least I'll get more power for an active crossover now! ;)

    Looks like it's gonna be a PDX 1.600 within a couple of weeks.
    I cut a piece a paper, and saw how big these are. Not big!!!

    The real question is: How do they taste? Did you use gas, or charcoal?

    I would actually like to try out the new PDX amps. The monoblock has 1200 watts instead of 1000 and it's got a remote bass knob that's very handy

    Nice! Does it look the same? I think 600w rms to my front and 600w rms to my sub is gonna be enough for me. ;)

    Yes they look identical except they have a trim ring around the amp that you can take off and they offer like 4 different colors lol that's kinda **** but different I guess :) I'm all about Alpine I think they're electronics are out of this world! Dunno too much bout their speakers and subs heard the Type-X subs before and sounded like **** had a type-r 12 once and my mono blew the hell out of it lol

    Sounded like **** you say!? The X-series is supposed to be good.
    I had Alpine's SPG-13cs component set before I got the Polk SR's,
    thought they were okey. But now I don't have any Alpine speakers,
    I only use Alpine HU (9855r) and amps, I really love those drivers. :)

    Type-G? Never heard them...but did hear Type-R comp at Best Buy one time and wasn't too thrilled by them...and I'm an Alpine guy. I think the enclosure dude had for his Type-X wasn't at all what it was supposed to be and I think it made them sound like ****. They dip down to 24hz which is pretty low for in car. But Polk SR's, Boston SPG, and JL w7 go as low as 20 which is really low and they're still set up for SQ where I think Alpine was more towards SPL and Kicker and Rockford Fosgate had them beat all to hell

    I really would like to hear some Polk's before gettin rid of my Bostons for new comps but have no way of it. I can go to my local car audio dealer and layaway Bostons, Rockfords and Kicker which is how I've managed to get my stereo LOL. They have the Pro SE's for $330 right now. I've been debating on laying them away honestly but I hear that the SR comps are nothing short of heavenly devine!

    Yeah, the SR5250's were the greatest purchase I ever did. And they produce great midbass with a kick.
    I have them crossed at 40hz right now (with a steep slope), with the subwoofer crossed at 50hz - sound greeeat! :D

    Is that on your BBQ grill?

    Anyway. i have never tried Alpine...I have a Kenwood amp and it seems to do well. Havn't had the ambition to upgrade since the kenwood was only 120 shipped.

    If you have a Fry's near you you can get a great deal on the SR5250 for $399. You could order it online if you don't for the same price. I was able to get mine for $299 a few months ago and they are incredible. If you are considering the Sr's, they are one pair of speakers that I would recommend someone buying even if it was a blind purchase.

    Well see I cant just shell out $400 for speaks right now. I simply cannot. I have too many things on my plate. But if I go to my guys and give them like 20 here 30 there I can have the Bostons with no time limit. So while the Polks more than likely are much better quality speakers than the new Bostons realistically this is the only way I can afford them right now. I'm a single man taking care of my kid full-time (proud to say) I dont have the help from the girlfriend anymore.

    It's worth $400. In Norway, it costs much more! But back on topic,
    anyone thinks 1.600 is a good match to my 12" JL w6? Or should I go with 1.1000!?

    Go with the 1000 you can never have enough power and if it's too much you simply turn it down...that way you'll never have to get another amp if you decide to get a new sub or 2 JL's

    We'll see. ;) As Installer said, the 1.600 is perfect for my sub (gives same RMS-watts as my JL can handle),
    but with the 1.1000 I have some "headroom" although I don't think I'll get more subwoofers later -
    only maybe switch to the SR 12"-sub. :D Also because of the money I think it's gonna be 1.600.
