3 way or 2 way active?

Last question on this, since the head unit controls the mids via rear rca jack, when i go tune those front mids thru the radio Will the rears , wich will be hooked up to the radio also have the same tune? If i use higher end fronts since they will be amped and lower end rears wont the sound be bad at the rears, especially if im tuning the bass

forget about the rear already. Always focus on the front stage which is the single most important part of your system.

if i understand correctly the CD player has a tweeter midrange and subwoofer output. so you if want to do a 3 way active system this would consist of.a tweeter, a mid range and a SUBwoofer.. so your crossover point would look like this

tweeter HPF 2500hz

midrange HPF 70hz-LPF 2500hz(this is called a bandpass filter and only the frequencies between 70hz and 2500 hz will play through the mid)

low LPF 70hz

if you wanted to say for instance run a 4 way active system you COULD use the mid and get a amp with built in crossovers to use a deadiciated mid bass and midrange.

sor example look at this amp.

DC-1004 - Zapco 4-Channel Class A/B Full Range Amplifier

if you used this ammp for your midrange and midbass drivers and used another amp for you tweeters you could simply use the CD players MID pre amp output and just use a splitter to the 4 channel. using channels 1 and 2 for the midrange and channels 3 and 4 for the midbass

the amp allows you to bandpass on all channels.

OMG this think is 599 fucky ****! i need to grab one!!

SAX-100.4 v.2

the sundown is alot cheaper and you can use it to do the same thing

the midrange on the front channel set at 500 and swiched to LPF and set it to around 2000hz

and the midbass @ about 70 to 400hz or so..

yes. but i highly suggest you avoid rears..

Ok so if i have an amp pushing 150 ish rms per channel , will i be able to match the tweeter if its 25 rms or lower

yes.. the gain knob is supposted to be used for matchin the cd players output voltage but you can set the channel for the mids higher then the one for the tweeters to balance the output.
