Cerb Sounds - sub woofer installs?
Discussion
I've seen cerbs with subs in the 'helmet holder' between the rear seats but are there any custom mounts available to do this? What are the other options if any - I had thought about a 6x9 sub in the dash hole under the CD.
Be interested in seeing any installs - I guess I'd want an active crossover to feed mid only to the (sorry excuse for) speakers in the rear pillars. Amp in the boot on the step with the control boxes?
Yes, I know I should be listening to the exhaust but sometimes you need a bit of Lewis Taylor . . .

I made my own enclosure for my 10" sub. Took some doing and managed to get the correct volume needed for it to work properly. Pic on my profile. Cant remember the sizes as it was a weird shaope to fit.
I done the same in mine, added a 10" sub and amp in the boot!! Get a much better sound nowWatching this thread with interest, as I made a start on this in early summer and shelved it due to my own lack of carpentry skills.
I've got a Rockford Fosgate 10" sub and amp to mount in the boot, I've calculated the volume for a seal, stuffed box (the only way I could get anywhere near fitting an enclosure behind the seats), and made a template for the front face out of cardboard. And that's where I stopped.
The front plate is kinda a figure of eight shape, and my plan was to cut the front and rear plates out of 18mm MDF, and join them together with curved panels made from a marine-ply sandwich (two sheets of marine-ply, fitted one at a time, stuck together with PVA).
Accuracy is a must, and my workwork skills are somewhat lacking. So if anyone's got an easier plan, then it might not have to wait until the next time my chippy friend comes to visit!!

Have a word with Carl Baker first - not only is he the TVR Alarm Guru, he is also the TVR ICE Guru, he baffled me with science about Sub Woofer installs in TVR's, that you don't need powerful amps in them because Fibre Glass cars absorb Bass frequencies that lie between the cosine range and sub frequencies of thingammy jigs and watch-ama-call-its 
There's quite a few of Carl's installs out there now. The setup is a replacement of the speakers front and rear, plus a pair of woofers in the helmet hole and a Clarion head unit Carl liked. Due to the sensitivity of the speakers they do not need an amp and because they are matched, the woofers give seemless extension of the lower registers. I've heard some of the sub installs and while they give plenty of volume, the don't have the same sound quality and the base is not as tight and punchy as I like it. The system copes well with the noise levels the car produces (no cats plus ACT big bore exhaust) but you only really appreciate just how good it is with the engine off. If you want to listen to my install to see if you like it before you part with any £££s, then just get in touch and we'll sort something out.
Cheers,
Steve.
ETA: One day I will get Carl's amp recommendation installed to see just how far we can take things (those interested have a look at www.sinfoni.com, perhaps something like this)

I've got a Hertz amp and 10" sub in the helmet holder with a fancy upgraded Pioneer head unit and speakers.. personally, if I was you, I wouldn't bother.
As mentioned, the base really isn't that great (didn't realise due to fibreglass!) and the quality is wasted due to the engine noise anyway....with the engine off it sounds great, by who would do that often enough to warrant it?

I disagree. I'm really happy with my set up and the base is good for me, even with the engine on. I agree you dont get the really deep 'boom' like base that you hear on the boyracer cars, but I havent spends loads of money either. Just to add, I have a Genesis Profile 4 amp in the boot and Focal components.As mentioned, the base really isn't that great (didn't realise due to fibreglass!) and the quality is wasted due to the engine noise anyway....with the engine off it sounds great, by who would do that often enough to warrant it?
If you want that deep rumbling bass, then you really need a large sub element in an unbaffled, ported box, and that takes space. Unless you're going to give your boot or at least a large portion of your boot over to it, it's not going to happen in a Cerb.
The lazy option is just to mount a sub element (or pair of sub elements) in a panel in the helment hole. This a "free air" installation - it's not terribly efficient in terms of watts-to-sound ratio, and it won't generate very deep bass, but it will beef up a semi-decent 4x 5.25" speaker install to the point where it's listenable on long motorway journeys.
My suggested compromise was to go with a sealed, stuffed box (stuffing reduces the size of box necessary to get the correct dynamic range out of the element). Still won't be a outright loud as a ported box, but it should deliver a strong crisp, punchy bass, without needing a massive amp.

Nice blacked out wheels on your cerb bruv innit! LOL 
I'm just looking for some decent sound without cutting massive holes in the doors or rear pillars. The way I see it is if you use the helmet hole the car is easily reversible to standard.

Repeating myself here Smash - But give Carl baker a ring, you'll learn a lot from him......
But if you want a decent sound without chopping holes all over the car, ditch the original front speakers - they are useless - and replace them with some decent ones like Quartz MB, tweeters and a good crossover unit. With a decent head unit you'd be surprised what a huge difference that makes to the sound.

I just wanted a little more depth to the standard setup, so added a Pioneer underseat subwoofer in the bottom of the helmet holder/cubbyhole, leaving most of the helmet holder available for storage.

Only 150w but fills in nicely.

Jensen - Hang on - what front speakers? I've got tweeters in the doors and cd sized drivers in the rear pillars but that's it - did they change later on? Message recd - will speak to Carl.
Byker - Been looking at underseat active subs and wondered how they performed but more importantly whether they'd go under the seat!
Mr M - only joshing, they do indeed look "wicked"
