Ya well see if I had no setup at all that 8 inch sub would be my first bet,

but seeing as I am 95% satisfied with my current setup and am just looking to find the little thing that would make it perfect I'm trying to fiddle with what I already have.

As you said about mirror shaking, since my current woofers are mounted right behind each seat, you can feel the bass in your seat AND it shakes the mirrors and windows at a decent volume without distortion.

The only real problem is that I can play 3/4 of a song with very satisfying bass but theres like ONE PART Of the song where there's a frequency drop and then all of a sudden everything that sounded perfect goes down in mad distortion for a second and then resumes.

I have the perfect example : Chris Brown - No ******** - YouTube

The bass that comes at 0:30-0:32 and 1:03-1:05 and many other times in this song just DISTORTS on the Altec like crazy but the rest will be fine. Meanwhile the logitech plays it very faintly. So it's like the Altec picks up on it, but can't play it right.

See when I said I was trying to learn more of the technical part of it I agree I can change the whole setup and I would be amazed, but I wanna nail down some stuff before I go ahead and do that.



And whenever I do decide to do it I have a friend who works wood as a living and is very well equipped in the matter, he also has a lot of scrap wood that we could use to build an enclosure, so some of you proposed I go about and measure the room I have for the biggest enclosure possible, my question(s) to that is/are : In my situation will the driver suffer from a lot of noticeable sound quality if the size that fits is smaller than the recommended VAS. And also, would it be overkill to go ahead and build TWO to have a dual 8 inch setup ?

Thanks guys

Does anyone think maybe if I pulled it from my truck and plugged it on my computer through my woofer amp, and have it bench with my TONE GENERATOR I could find the frequencies at which it fails..

And then I could just calculate the capacitance I would need to eliminate the frequencies below a certain level to keep it clean on sound while doing a good job on the rest.

I have a question on doing this, when you calculate the 'Crossover frequency' correct me if I'm wrong but this means that you calculate the frequency at which the signal 'BEGINS' to enter so for instance if I choose 60Hz, everything below that is attenuated correct?

Even though this may not make sense for some audiophiles, since the sub basically plays at a respectable volume, has me satisfied most of the time I'd be as happy to just cut off whatever has it distort and enjoy the rest of the frequency band without me worrying about losing a couple Hertz on it.

Thanks!

Can you find a way to burn a CD with bass frequency?

I think they sell them.

I downloaded some tracks yesterday with bass tests and it does really really well, even on some CHILL LOUNGE type music with lots of high definition bass and it also does very well it only distorts with the volume is relatively high and it hits those LOW rumbling frequencies, so since I have two woofers, and only one acts up I was thinking maybe I could filter those frequencies from it. Because if it was a POS all the time I'd just rip it out and change it but its quite surprising the rest of the time.

Hi,

Sounds like you have a boombox, OK most of the time until you hit the
boom. Go double logitechs or double new drivers, stop messing around.

rgds, sreten.

Default Chevy Owners

Here's an case in point: I had a 2000 Chevy xcab Silverado, factory Cd/Radio, the one that looks nice but not much power. I made up a cardboard box to fit under the R-seat, from there made a MDF box, [btw, had a 3" x long port, but I got it tuned] and a RFFG 8" P3.

Since it was a factory radio, I never went near it, picked up a speaker lead from the back (only 1 side I think). May have used a punch 45; what the heck did 45 mean?

Oh boy, that think rocked, I still remember the windows and mirrors shaking, and loud, It just kept going.........

I had friends that took Suburbans to car shops, and had everything done; and they still sounded the same :-/

I had a blast with the RFFG combination.

Was just looking through ebay to keep my 6.5 inch and get something not too pricy..

Came across this, but have a hard time believing it can do so well what do you guys think :

6-1/2" Subwoofer 6.5" Sub Woofer 80W RMS / 160W Max 4 ohms BIG BASS small space! | eBay

Seems like it would improve what I'm looking to find if it does what it says.

Cool thanks I was looking at that kicker sub at 64 should do the trick in my opinion, with shipping and all comes to 100$... I wonder if I'll have to do some hacking and sawing to get it into my current enclosure I'm not sure if its a 6inch or 6.5 inch.
