bass going to my factory 4". s'ok?
 

ok. everything is almost all done except now i have the deck (sony cdx-gt200) <url>http://sm.crutchfield.com/S-pGiR6e6DWh4/cgi-bin/ProdView.asp?g=300&I=158GT200</url> that has amplification but no builtin crossover sending all frequencies to my 4" stock speakers (which are my only speakers besides the 10" subbox).

my question: do i neccessarily have to cut out the low freq to the front speakers? will the natural roll off of the speakers be ok or will i be damaging them or hear all kinds of distortion if i keep them full range?

thanks.

You could hear distortion (depending on the volume), and you could also bottom them out, and wreck them.
I don't run any crossovers on my mids, and I ended up having too much bass go to my rockfords, and ended up wrecking them (after 2 years though).
So you can do it, but it's probably not the best idea.

If you don't have built in cross overs on your amps or are unable to use them due to system set up etc... just use some bass blockers(capacitors) to cross them at your desired frequency. For a 4" driver I suggest at least 100 hz or higher(400 microfarad for a 4ohm speaker at least 16volts or higher will work well).

thanks vee.. didn't even know they existed...

but it brings me to another question:
you think the 4inchers can go down to 100hz?
crutchfield.com suggests 600hz for 4" speakers. my question is all i have in my car are the stock 4" and a 10" sub. do you think the sub will cover up to 600hz? can i lower the crossover freq of the 4"?

i guess there's a natural roll off for that size a speaker. i don't want to add any mid's. just trying to add a little thump to my stock system but don't want to kill the 4" or have a huge gap in my freq range.

thanks.

600hz is probably if it's in a three way component set, where the 5.25, 6.5 etc.. will handle everything from say 80 hz-600hz, the 4" would take over at 600hz-5khz(about) and tweeters take it from there. If you are only using a 4", then 100-150 hz should be o.k. and cross your subs at about the same point. I'm currently using 2.75" stock speakers(Infinity mids) at 100 hz point with no distortion at high levels daily. I've used 3.5" co-axials for years in my previous mustangs crossed at 100-120 hz with no problems also( those i used for 5 years, until I sold the car). Just remember that distortion can be caused by poor source material, improper set up(gains too high, underpowered/overpowered speakers etc...), and the user's improper use of the volume control.

thanks vee.

someone just suggested that since my deck has a subwoofer controller just turn down the low's from the deck (which won't effect the sub since it has it's own controller) and that should be sufficient.

you think that's satisfactory?
