Subwoofers - Range

I doubt a 6.5" driver will go as low as 30Hz, probably 45 at best. OP you can grab an enclosure online or build one if you fancy a DIY job

If my headphones can go down to 5Hz then I'm sure a 6.5" sub can if it's good enough ;)

It'll vary a lot depending on budget though I would guess if its anything like headphones!

It's entirely dependant on the enclosure. With the most common type of enclosures (infinite baffle or reflex) a 6.5" sub isn't going to be useful anywhere near that low a frequency unless it has an insane amount of throw. For these basic enclosures bigger is generally better for the driver in terms of output at low frequency.

Yeah there's definitely a lot more to it but I think the general gist of a lot of messages in here is that size isn't everything :D hehe

Right amp, enclosure and sub will make more difference than just the size I'd imagine. Whether or not the OP can afford the right kit is another matter though hehe
 
I went to see a friend anb we got a whole load of the trim off in the boot, and took a look at the sub. There's a small circuit in it, which seems to amplify it. It turns out that it does actually work, but is incredibly quiet. My head unit is just underpowered. So, I've ordered these speakers:

I'll install these in the front, and probably upgrade the rear door speakers too. Then I'll see how it's working, because it looks like my head unit doesn't support a sub properly, so I'd need to get an amplifier and then probably, again, a new head unit. So, I'll see how it goes with the new speakers and then consider doing the rest. I do want to build an enclosure for the sub, that'd be fun :D
 
What headunit is it? It is more likely that the sub you already have is 8ohms and not 4ohms which is what most headunit amps are designed for. You need to run it off an amp ideally anyway. PLEASE don't use a tiny amp kit to install it. 4gauge minimum please. I used 0awg for just 800wrms once, epic overkill, but never had voltage drop problems that plague people who try to do it on the cheap.

Perhaps you should enlighten everybody with your research then instead of sounding like a knowitall? Its generally accepted wisdom and the reason you don't find many 6 inch subs. People don't want to faff with building transmission line boxes just so they can demo their 6 inch sub, so the trade off is larger cone area.

I have to agree with 18s and dance music, they are fine. I fitted 4 into a smart car back in 2002. Anyway, I digress. The original question is related to confusion, where the op is looking at speakers not subs.

It is wrong and it is more wrong to keep telling people said "wisdom" :rolleyes: That way no one ever learns the truth do they?

I guess I am a know it all when it comes to ICE :)
