did a search the best info i could find was to buy a meter reader from radioshack (i'll get one from amazon.co.uk or something) ... that was about it. just wanted to know where i'd go from there really. how much to spend on a good level meter? are there any programs that already have a function for cabin gain? how accurate is it? etc, etcdid you search?
No, with a car there is no need for the circuit-I'm using the cabin gain instead of the circuit. I had thought I'd need some EQing too but on initiall listening I've needed none. For yourself a similar car is possibly good enough to have the same results as me-I've added some more to the other postbaron, just read your other thread/post, you built that little circuit i take it? how exactly did you model that in BBpro with cabin gain if you don't mind me asking? i don't think i got it right. like i mentioned in my previous post i found a pic of a similar gm car and tuned accordingly with so-far-so-good success.
That's what i did using Andy W's graph as a guide, if you really wanted to you could measure yours for more accurate results-but do consider that my modeled output is MUCH peakier than my measured response in car-though this could be down to an RTA on my phone with no seperate micbassbox 6 pro has a section where you are able to input values for cabin gain if you know them so that you may tune/design to adjust for that.
Glad that's working for youfor my situation, I simply looked at the graph of the similarly built vehicle and noticed roughly a 15db increase at ~43hz compared to ~60hz. brought that area down a bit, boosted near the subsonic point a bit and thus far, things are good.
So what are good Sub software. I got WiniSD pro, but the WiniSD Beta has a better 'pre' selected choice of subs (just messing around and clicking buttons at the moment).I was fortunate that I found my transfer function mapped out by Andy W in the graph mentioned above, so just entered the info into BBpro.
have you got a picture you could share?I factored in the cabin gain when designing my system and ended up running my sub in a 0.125cf box in the front footwell. The design is unusual as it dictates the FB has to be HIGHER than the range you intend to play the subwoofer. So my subwoofer's output starts to roll off ABOVE 100Hz, the sub system has an F3 of 76.84Hz, Fb of 76.32 (modeled not measured yet) The sub only just fits in it the box, but it handles everything I throw at it and is flat from 30Hz to 63Hz where it's LPF'd (measured with pocket RTA and white noise) google Linwitz Transform.
Like I said anything (pics) would be a help. Still looking to get into box building myself because no one in my area does it and all the kids are wasting their money on ... not good stuff. My friend has just spent £600 on a Vibe Black Air 12 sub, Vibe Black Death 6x9's and an amp. When he heard my system he nearly broke down in tears (Morel Tempo 6 mounted in the kick panel, DDLE312, JL audio amp).Will get something up next week-busy weekend, you will laugh when you see my 1st attempt at trimming a box-looks like Stevie Wonder and an elephant with premature ejaculation issue had a field day with it! Fortunately the bit you see looks fine!
I'd cry if I'd spent any money on Vibe! basszone in wolves build "pretty" good boxes, if you give them the dimensions they'll make what you want. Only pinned together, though you can order un-carpeted and screw them up yourself if you were concerned. I had mine made by a carpenter mate of mine, more than basszone, but better built.Like I said anything (pics) would be a help.

I really want to get into this though. been reading up a lot just need to find space and tools now.
As for me I need to rehouse some of my enclosed subs. But I promised my friend when i get started I'll build him an enclosure for his Black Air, however with a QTS 0.632 i'm thinking a sealed enclosure might be best.

Back to Cabin Gain
So once i've got my figures for cabin gain, what do I do then? what do i need to do to make the bass less 'boomy'?
