Crescendo PWX's and FT1's question

[Ace87]

Recently I ordered 2 pairs of the 8 ohm pwx 6's, and obviously the 2 pairs alone will have my sundown sax-125.2 running @ 4 ohms. My question is, is if I got 1 set of the 8 ohm ft1 tweets with the inline crossover, would that then present a 2 ohm load, or would it stay the same? I was looking to run the amp @ 2 ohms because it's only 125.2 @ 4 ohms. Would I have to have 3 sets of 8 ohm pwx 6's and one set of 8 ohm ft1 tweets to see a 2 ohm final load at my amp? Thanks!

you need 3 sets of PWXs.

2 set of pwx and 1 set of tweeter = 3

8 ohms divide by 3 = 2.66 ohms

3 set of pwx + 1 set of tweets = 4

8 ohms divide by 4 = 2 ohms

very simple

Ok, well in your opinion would the sax-125.2 be enough for 3 sets of pwx 6's and 1 set of the ft1's? It's 225x2 rms @ 2 ohm, and is more than likely underrated. One other question, because I don't think I have a very clear understanding of crossovers... With the ft1 hooked up using the inline crossover, that means hooking it up in series to the 3 sets of pwx would mean the impedance isn't effected right, so they'd all be running @ 2 ohms? Now if I hooked it up without the inline crossover? Would that make the 3 pwx and one ft1 on each channel be @ 1 ohm instead of 2 ohm?

it doesnt matter, the crossover is just to prevent frequencies from reaching the tweeter, doesnt affect ohm load at all.. check the previous comment for the math on ohm loads for single voice coil.

Ideally though you'd want a 4 channel or two 2 channel amps. If you cant adjust the gain on the super tweeters, your ears will get destroyed because they are harsh AS F*CK with anymore than 20 watts going to them.

Simple enough, I didn't realize figuring it out would be the same as wiring subs.. I thought the crossover affected the overall final ohm load or something. I've got alot of learning to do, and with a little help from people like u on here from time to time, I'll get there. Thanks man

You do NOT want the mids and tweets on the same channel of the amp as the mids will take WAY more power. You will blow tweeters all day long doing that. Tweeters on diff channels or a small 2ch amp...
