Help Upgrading Me 1st System(Newer)

get 2 extra speakers..lol

 

parallel the left speakers to one channel and parallel the right speakers to the other channel.

 

well the croosovers are ussually used with component speakers, if you buy 2 ways or 3 ways they have an internal crossover if im not mistaken. so that means you dont need the crossover, anyways amps ussually have internal crossovers. you should check if the amp's RCA's are connected right cuz your HU has an internal EQ and it has 3 pairs of RCAs 1 for the front speakers and one pair for the rear(they are probably not being used right now) and 1 pair for the sub.

 

holy crap they raised the prices of the amps...

 

Coaxial speakers have passive crossovers for the tweeter but not the woofer

 

but there is no need for a crossover if you have an eq right?

 

wrong.you still need to have a xover on your speakers.

all an eq does is boost or cut certain frequencies.

a xover will keep a speaker from playing certain freqs that it cant play. like cutting sub bass from a mid range,and vice-versa

 

thats not 100% true.my polks have a coil for each speaker.

 

ok..i had a 7800 and it has the ability to send subbass to the rear speakers.most likely for some one without subs.

so go into the menu section and see if you can change that.
you can also turn the subout on/off.so check that too. it might be off

 

so if i want the speakers to live longer i should get a crossover??

 

yes!if a mid tries to play bass for too long it will eventually die.same with a tweet.if its not crossed over high enough it too will fry.you also dont want a sub to try and play mid range.

this is how my set up is crossed over.

infinity dash plates (600hz hi pass 12db per octave.)they also have their own crossover that came with them.1 for the mid and 1 for the tweet.12db for the tweet and 6db for the mid.

my door mids-(80hz hi pass )from my HU.12db per octave.
since these too are coaxials they also have there own crossovers.

rear 6x9's-100 hz hi pass.12 per octive

sub-80hz low pass 18db per octave.

 

does any of that help?

 

and you need one for the sub too??

 

yup..............or else it will try and play all the frequencies from 20hz to 20,000hz.

 

a sub should be crossed over from 80hz and lower.

a good set of mids from 80 or 100 hz and higher.and tweets from around 3000-5000 hz and higher

 

damn this is bad news...lol more stuff to the list

 

whats the lowest frequency a sub should go

 

umm...... not sure.most music these days dont have super low bass.


tell me what your system cosists of and we'll see what you need and dont need.

 

well i have the 2 audiopipe 15' subs, 1 power acoustik amp rated at 760 rms, 1 profile baja amp rated at 480 rms, 4 kenwood 5x7 bout 50w rms, blaupunkt HU, boss equalizer and thats pretty much it
