I have finally got a sub on the way, but ant afford any decent main spkrs yet, I am wanting to run a set of Crossovers between my deck to my std fron spkrs.

What i need to know is what frequency should they be set to run above? You can buy kits from jaycar and cusomise the frequency I just need to know what my main spkrs should be running so they dont die when I increase the bass to my sub which has its own lo pass built into the amp.

Or if anyone has any old passive crossovers from a pair of splits they no longer use or want and wanna sell lemme know.

Note.....I know this isnt ideal way to run the fronts but, until I can afford my Type R alpine splits and V12 to run em this is my only option and I dont wanna pop my main spkrs within 10 mins of adding the sub.

Any help hugely appreciated,

Luke.

It depends how loud you want to play them and what sound you want from them. If you want as much volume as possible you'll want to set a fairly high crossover say above 100hz
If you don't listen that loud, but you want good sq, eg midbass upfront. Then you can afford to go lower... Down to 50 Hz and below with quality speakers, but if you are using stock speakers I'd go around the 80 Hz mark with a shallow xover (say 6~12dB/oct).
This "slope" determines how quickly the frequency is attenuated.

Remember no crossover is a brick wall, it will still play levels below the filter point but these will be attenuated according to how steep or shallow the slope is.

If you are after sq you want your subs as low as possible, generally around the same area as your fronts. eg: fronts high passed at 80 hz, subs low passed at 80 hz. This way you will not notice your subs which leads to good staging. You can also blend in the two crossover points (subs higher, fronts lower).

Of course this is all dependent on what you like, what you have and what you can get.
If you pass your fronts at 100-150hz they will be able to play very loudly without bottoming out. This is where your subs can take over.

Thanx for the help, I think ill go for 80hz with 6db/oct as they are the stds in a TF advanced, this will at least stop em from producing the low freq's so they will hopefully last for a couple of months, until I can get a decent set of splits.

Which will be my next prob, whgat brand of splits, I dont wanna go above $300, I found a pair of splits on ebay, after doing a bit of looking around they seem to be a lot better than what they price would suggest. They are Kicker K65.2's and they are asking only $95 +p&h.

I found a similiar set which are the 60.2's which have lower pwr handling ie 50wrms to the 75wrms of the 65.2's but these retailed for almost $300, so it seems that the ones on ebay are too cheap to be any good.

arrghhh dilema's

Cheers

I've put my splits to a 100hz, 12db crossover thing...and i don't have a sub....yet

yep thats a good price. But front splits are prob the most important aspect of your car audio. So I'd put the most thought into them. Try Hertz HSK-165. Very powerful for the price. Then there's morel, dynaudio the list goes on.
www.caraudioaustralia.com in the for sale section. There's heaps of stuff going there for cheap.

Factor in money for an amp as well. Even something cheap. Will sound much better and also give you some more crossover options. Even a $100 2 channel amp will get heaps more punch out of your splits than your headunit. Also sound deadening etc...

Don't waste your time with temporary fixes... Just costs more in the longrun. Put up with your sound for the moment, save up some money for good front splits. Or buy a small 2 channel amp now. Run your factory speakers off this, it will have it's own adjustable crossover and you can use this to run your splits when you get them. You will not be doing any splits justice running them off a headunit. Headunits will put out around 20 w rms (even if they say 4x50 etc... Decent front splits will handle over 200w rms.

Theres some food for thought
