Amp / Sub selection....

I didn't say you should overpower them either, did I? Running too much power to a speaker isn't a great idea either. My point is that you shouldn't run something severely under the suggested RMS just to make the speaker quieter. I tried this same thing in my first car and it's horrible. Why get a 300 watt RMS speaker then starve it of power? Why not get a 200 watt RMS speaker and provide it with the suggested power handling?
Clealy, running 100 watts to a 750 RMS (E.G. L7) speaker is probaby not smart, since your not even close to maximizing it's potential. I ran the 500.1 JL audio mono amplifier to 3 JL W3's and I was underpowering, but it definitely had enough juice. From my previous experience with car audio, you don't need to push the subwoofer to the maximum RMS. I'm not going to turn it up to the max ever. Regarding distortion, harmful effects, and bad sound quality when underpowering, I have to disagree.

i'd like to hand this one off...

Alrighty...here is what I got. I went to Best Buy and listened to the Clarion. (I did not buy from Best Buy....I went to www.cardomain.com) Wasn't the best, but sounded better than the Sony (very limited budget), and I got it for $45 shipped to my door. Seeing as I am pretty much just looking for a speaker to fill in the low notes, not be extremely accurate, I went with the Clarion SW10x (their entry level speaker). It is rated at 300W RMS@4-OHMS and 600W peak. I chose an Infinity Reference 2-channel amp that bridges to 283W RMS @4-OHMS ($99 shipped).
Like I said earlier, I once had 2 10's pushing only 300 (Alpine V12), and that was almost too much for me. Hopefully, seeing as there is only 1 speaker, not quite as big an amp, and a convertible it will work well.
Does anyone know if the Infinity "pushes true amps?" I have heard that some companies measure amps different (sony is a bit low, while MTX and Fosgatte are generally a bit high).
One last question.... The sealed box I have made is approzimately .81 cubic feet. The Clarion recommends a sealed enclosure of .7 cubic feet. Is the additional .11 going to really affect the speaker? I could always just shave the sidewalls down until I get what I want, but that is a TON of sanding.
Thanks

I'm running 320 watts to my Brahma which SPL competitors have fed close to 2000 watts.

How loud is the 283W going to sound? I am looking for a nice balanced / full sound. Also, the sub is supposed to mount in .7 CF sealed. My box is .81CF sealed now. How will this extra volume affect the sound. Is it worth sanding for only .11 CF?
i like to overpower my speakers anywhere from 15 to 33%. I'll never turn the volume up all the way and i can adjust the gain settings on my amps accordingly. I feel that too much power is a better solution than not enough. You can adjust your volume by that knob on your headunit, and you can adjust your gains on your amps so you will never blow your speakers. But I prefer to have the gains pretty high and just adjust the system via my headunit. I go to great lengths to prevent idiots from "seeing how loud it is," because i know that they can destroy my set up by turning the volume to it's max. By overpowering my speakers they seem to "breathe" better and perform effortlessly. plus my amps stay cool.
As far as i know infinity underates thier amps, so you should be fine.
as far as your sub is concerned, from what i understand your box is currently too big, correct? So i don't understand how sanding it will help your situation. I would put the sub in the enclosure and listen to it. If is sounds loose and boomy and it is wired correctly i would consider taking up some of the volume with "great stuff" a foam filler on the inside of your sealed box. if it gets too tight, then remove soem of the foam.
Polyfill, btw, will actually fool your sub to perform as if the box were bigger not smaller. It's crazy math concerning surface area vs. volume. PJK3 can readily confuse/ teach you how that works.

sounds great. IMO sounds better than most jl, ed and even some re subs that are running closer to their RMS wattage
