going active

[orioles26 10+ year member]

Ive been reading about active setups. If i have a set of kicker rs6.5 components and a four channel amp can i just run the mids off channel 1+2 and the tweeters off channel 3+4, or is it more complicated than that? I am thinking of upgrading to a headunit like the 880prs but is a headunit like that necesary? Do i still use the passive crossover i got with the set?

nope use the xovers in the head unit.

No, you wouldn't use the passive crossover...that's the whole point of going active, you aren't tied down to a fixed passive Xover //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

If the amp you choose has good internal crossovers, you can just use those...but doing it from the head unit is a lot easier and intuitive anyway, IMO.

active means you get rid of the passives. basically what you do is run your highs (tweets) off channels 1 & 2 and mid/midrange off the other 2 channels. now you need a 3-way xover which the 880 has. what you'll do is hp your tweets say 3khz. lp the mids at 3khz. and hp the mids at say 60-80 hz. this is called bandpassing, then your sub xovered at 60-80 hz. low pass

So how do i run the rcas since i have 4 channels but they are all for the front.

front to channels 1+2, rear to channels 3+4, sub to sub

but the issue here is is there a point to running active when you have a passive filter set up for those exact mids that has gone through a huge R&D process?

is it worth your time? is there upgrade possibilites in the future for maybe a dedicated midbass to be active in that setup?

those are the questions you should be asking yourself //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

because currently, that passive filter is pretty much the best that you will likely be able to get those components to sound. even on an active setup, you will likely be setting your filters to around the same frequencies.

is it worth it? in my oppinion, not at this time.

is it worth it to upgrade? imo? it always is //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

will it be a lot of fun to do? sure! but you might not get any sq gains out of it.

will you learn anything? yep! espically in the future you decide to get new mids and tweets and activly filter them yourself!

The intesive R&D done to select those points also werent' done in his exact car. Even on a passive set, he may get benefits if he does it properly, depending on his mounting locations and his cars trasnfer function, reflections, etc.

What is R&D?

 

[iceteebone 5,000+ posts]

research and devlopment

tee. i know that.

but are you seriously honest that he will be able to hear the minute upgrade in quality that all that work running wires and setting up the crossovers will get him?

99% not in my oppinion.

it might pull the soundstage up a bit. maybe clear up a bit of cancelation.

the best think IMO for a "upgrade" for this system would be better aiming of the midrange and\or tweeter, some deadening in his mid range locaion (doors im guessing), and time alignment.

going that direction would yield a much more audible gain in quality at this point.

as i said before, it might be fun, but with the current equipment, its not worth it. but again, thats just my 2 cents. i will never go passive again, BUT thats just me.

Looking at the 880prs and it says it has a rca input. Can i use a 3/8" to rca to plug my ipod into the headunit or do i have to buy the ipod adapter thing.
