Hi I am a newbie in this car stereo scene so please bear with me... 
A little background, well, just recently I thought I'm just going to replace my stock stereo with a decent setup because I'm tired of the stock sound quality. I just purchased a Alpine cda 9887 head unit and I have some questions on component speakers and a matching sub (yes, just one is enough for me) and amps that'll go along with the whole setup.
I have a alpine F300 amp (4x50w) in my possession as well and I'm contempolating to purchase two sets of Alpine SPR 17s (rms 110w) for front and rear stagings. On top of that, I also have one alpine mrp M450 (1x450w).
My questions are as follow:
- Will the Alpine F300 amp (4x50w) be sufficient to power up two sets of Alpine SPR 17s? I do noticed the deficiency in the wattage department (numbers-wise) but, will this degrade sound quality output from the two sets of SPR 17s?
- considering that I mostly listen to pop, rocks, occasional trance/rave musics, would it be better if I go with type-r sub instead of type-s sub? The reason for this question is because I own alpine MRP M450 amp (1x450w) and if I go with the type-r then I might have to go with a higher wattage amp.
I appreciate inputs and attentions from all of you car stereo gurus outthere

agreed with the above.
basically, you want something like this

keep in mind that Alpine M450 wants a 2 ohm load. that means you want a dual 4 ohm sub wired in parallel.
take the money you're saving on the rear comps and buy some good sound deadner - second skin or dynamat extreme. deaden and seal up those front doors.

Guys, awesome replies and very informative! Keep it coming!
Stereo gurus, where do I find the MRP M650 and MRP F450 brand new? I googled both of them and seems that of them are discountinued?
What are the replacement products for the items above? Could you all please point me in the right direction?
I looked at Alpine PDX series but I can't afford them as their prices are quite steep..

Basher8621: Hi! Sorry for the late response. I went to my hometown for a couple of days and just came back earlier today
Yup, I'm planning to purchase those amps from any Alpine authorized dealer. Crutchfield is a good source but is there any other online autorized Alpine dealer? For a compare-and-contrast sort of thing :). As far as budget-wise, will $400 to $500 be sufficient?
keep_hope_alive: Thanks for the link, I'll check it out!

Stereo gurus, from "search" I did, I found out that it is better to over power (more control and leeaway in tuning) instead of under power. So with this in mind, is it safe for me to say that I'd be better off to go with Alpine MRP M850 to power a 12" type-R sub? Or, should I just go with Alpine MRP M500 instead?
Thanks!

keep in mind that "over power" is not an accurate term. never give a speaker more power than it's rated for.
what you want is an amplifier that can put out more power than you plan on using.
the M850 gives you flexibility in the future if you want to run multiple subs or a larger sub later on. it would rock a Type-R 12.

keep_hope_alive: I found another option, that is, the MRP M650 (600w rms x 1 @2ohms). I'd think this M650 should give me enough headrooms in tuning? Although it won't give me ample headrooms and flexibility as in M850, of course.
What do you think?

So let me repeat, but please do correct me if I'm wrong: - MRP M450: albeit a little low on the wattage, this amp is enough to power a single 12" dual coil 4ohm type-r. However, won't deliver the best possible results. For instance, (perhaps) some distortion in higher volume, etc
- MRP M500: a perfect match for a single 12" dual coil 4ohm type-r. However, this amp won't give me much flexibility if sometimes in the future I want to run multiple subs or a larger sub
- MRP M850: will definately rock a single 12" dual coil 4ohm type-r and will give me flexibility for future upgrade/changes
Am I correct so far? -L-
exactly. spot on. couldnt be more correct. i say this from experience- im running my type r dvc 4ohm with 400w rms... it rocks the sub but at full volumes i do feel it gets a little distorted.
im using the D7400GM from pioneer right now. i should have bought the D8400GM which would be a perfect match for this sub at 600wrms. its small footprint, doesnt get hot (barely gets warm) and is highly efficient on power usage. you might want to look into it, i love this amp.
