buying a subwoofer amplifier

[audio amateur]

I just ordered the sony Xplod XS-L121P5S car subwoofer rated at 350W RMS (4 ohm single VC) to use in my "DIY" project. I'm planing on building a home sub, with this driver. I was searching a sub "plate amp" and I finally came up with the Rythmik audio 350 :

Do you think this is a good match for the sub? Is this a good amp? Also, the inner volume I am planing to make it about 1.6 cubic feet, with a 4 inch diameter port which would be 10 inches long, in order to give a box frequency of about 40 hz. Does this sound good? The only problem is that I dont know what sony recomends as far as inner volume for this sub in a ported enclosure... I think 1.6 is fairly big for this sub. but if I want a box tuning frequency of 40 or less I need to keep it this way, considering the fact that I cannot have a longer port because of box dimension restrictions..
My primary concern is the amp.Thanks for posting for any comments.

I don't think you'll be happy with that sub. Is it too late to cancel the order? Why would you order a car sub (and such poor car sub to boot) to use in a house?

hmmm well good question. To be honest I doubt it's as bad as you think it is, I have read reviews on it and it seems to hit fairly well, and the sound quality can't be that bad. I do have money restrictions as a I am in high school, and I have found few french web-sites (as I am living in france) that sell subs this cheap (at lest ones that are in its league). Anyhow, I have done a bunch of research and I don't think I'm going to cancel order, because I doubt i'll find any better for the price. I guess i am quite attracted to the design of it, and it's specs seem to match what I am looking for, even though it is quite cheap. Do you have any alternatives in mind? comming back to the amplifier, please tell me what you think (you or any others of course), because I am not familiar with the brand.

Well the problem is, it's designed to work in a car..not in the house. Not saying it won't work at all, but it's just designed to work in a tiny enclosure in a space that is very small (your car) and enclosed. Car subs depend on your cars natural boost of low frequencies, which is why they don't have much output below 50hz. Your room is completely opposite...it needs a sub that can move tons of air, and car subs don't.

Perhaps your right... I'll give you feed back once it's done.. however im still concerned about the amp. Anyone have any experience with Rythmik audio amps?

Nothing wrong with the amp at all. I worry it might be too much amp for the woofer you're using. Does the sony woofer have t/s parameters? That's really the only way to guess any kind of performance or required box size.
N. Abstentia is right. Car subs are designed to work in small enclosures and get loud. Sound quality in a house probably isn't something it was designed for, but that doesn't mean it won't be okay.
But if you have any other options, I think you'd be doing yourself a favour. Decent woofers aren't very expensive, especially in Europe where some of the best driver manufacturers are.

The piston area may look strange because this is actually one of those octagon shaped woofers. It's not round.
