Buying a component set piece by piece.

[derek33 10+ year member]

as for RE comps... i see they cost 165, pretty nice. how many watts do they handle?

for the xxx... how much do they cost and is that just for midwoofers? if they are cheap enough i could run the re comps and xxx mids. unless the xxx is a whole set.

thanks

50 or 75w I believe is their RMS rating. How much they'll actually handle is setup dependent.

The XXX6.5 comes only as a mid, not as a full component set. FYI, you can not run the XXX6.5 mid on the crossover for the RE RE comp set, if that's whay you were thinkin'

I think ive come to a conclusion to get these:

http://www.thezeb.com/p-CDT-Audio-C...stem-101083.htm

and two dynamat door kits from that website to double layer my two front doors.

run one amp for mids, one amp for tweets.

everything sound ok?

1) Linky no worky

2) Don't waste your money on the Dynamat kits. For about the same price, you could get 62.5sqft of Raammat: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=67760&item=5760607605&rd=1&ssPageName=WDVW

3) Is that comp set bi-ampable?

heres the link.

ill check to see if their bi ampable in a sec.

 

[derek33 10+ year member]

it doesnt say

Should be bi-ampable, going by that picture. Looks like it has two inputs.

[imputs] what are you looking at? the x-overs?

also, wouldnt running an active setup put 120w into the mids 120w into the tweets, isnt that alot?

thanks again for your help, squeak. youve been great.

edit, how many sq ft of deadener(sp) do i need for 1 layer for 1 door? roughly.

( its a jeep grand cherokee so they are kinda on the big side.)

Yeah....and I just realized I was wrong //content.invisioncic.com/y282845/emoticons/wacky.gif.cf4a48f9e6dfe9504ffd2c946fd2f340.gif They are not bi-ampable via the crossover....I forgot CDT has that stupid Imaging tweeter spot on the xover.

You could still run them active if you wanted though....just ditch the passive xover.

also, wouldnt running an active setup put 120w into the mids 120w into the tweets, isnt that alot?

But remember.....even if you only used 1 amp (rated 120w x 2 @ 4ohm), and ran the comp set using the passive xovers; each tweeter and each mid would still be receiving 120w, since the passive crossover distributes the frequencies, it doesn't split the power //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Quick way to find out is to take some rough measurements //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif I'd just take rough measurements of your door, then add probably 1 extra foot to each measurement (just to allow for some overages).

when you say "ditch the passive x-over", does that mean to buy new x-overs?

it seems like a waste to me to buy this set just to replace the x-overs. are there any comp sets similar to this, or better, around the same price that i can run an active setup?

thanks again

Well...apparently either I don't understand fully what you wish to do, or you don't fully understand what an active setup is.

When running an active setup, you are using an external electronic crossover of some sort (be it a whole different piece of equipment, or using the crossovers built into the headunit) to create the crossover points for the speakers. So, you'd use the active crossover to highpass the tweeters, and bandpass (highpass and lowpass) the mids. In a setup like this, an active crossover setup, there are no passives used.

This is where the confusion apparently is //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif You say you want to run active, which would entail not using any passive crossovers.....hence the reason I said you could ditch the passive crossover and run them in an active setup like you have mentioned you wish to do a few times now.

oh, i thought active meant putting the cross overs before the amp so only those frequencies are amplified.

Well, in an active setup the active crossover does come before the amp. But, you can't just put the passives before the amp and call it a day....that won't work (even if it did, it would be pretty much not worth doing). You need either an active crossover or a HU that has adequate crossovers built in. And an active setup totally eliminates the need for the passives.

oh i see, you use your headunit as a x-over. Mines a pretty cheap kenwood, and i dont think it will do a sufficient job.

I will probably just run the comps regular way, and just use one of my amps. i could probably sell the other.

I have a question. I was thinking about running an active setup but here's where the confusion comes into play. Ok...let's say I have a set of Mb Quart QSD 213's. I ditch the passive x-overs. Now...how would I power the tweets? I know I'd run wires from the radio harness to my amp to power the midbass speakers. But how do I go about powering the tweets?? And what about RCA's?
