Does it make sense to run seperate channels for tweeters and mid's? I'm using a 4 channel mixer for my fronts but channel 1&2 are Right and 3&4 are Left. I'm thinking I would be better off doing 1&2 as tweets and 3&4 as mid's. I have xovers but then I can further fine tune from the amp.

Thoughts?

 

So I tried to figure out which wires were coming from the tweets vs mids as they are wrapped together going into the amp now. 4 channel amp bridged. When I did this they all played ....so I checked out the specs of the xover and it has some configuration that shows that works. It also seems to have a few other interesting configurations.

Here is the manual: http://vault.alpine-usa.com/products/docum...OM_SPX-177R.PDF

What xover setting would you use for running the speaker wires? I'm also thinking about moving the xovers from out of the door to into the trunk. Someone said I could use a double A battery for this?

Any ideas on how to best run seperate channels for each speaker with this xover? Or do I just get rid of the xover all together?

 

Come up to my place, I'll help you sort it out


What you're thinking of doing is called an active xover setup, and the SQ will be much improved.

 

where are you located? Thanks!!!

I have this sort of set-up, with the components bi amped.

I take the "front" left and right signal from the HU, and then split it in two before connecting to the amp inputs 1, 2, 3 & 4.

I have the tweeters wired to channels 1&2, and the woofers wired to channels 3&4.

I have the high pass filter in place on channels 1&2, set to the maximum setting of 500Hz - no need for the amp to be working to produce these for the tweeters. Channels 3&4 are run full range

These are then connected to the crossovers (which are door mounted) which makes sure that incorrect frequencies are not sent to the woofers and tweeters.

Essentially it's the same configuration as shown under "Bi Wire Input" on page 12, although with one 4-channel amp rather than 2x2channel amps as shown.

 

I knew it ! I was going to remove those two jumpers yesterday and I said let me just hold off and check the manual which I don't know how i missed that. COOL!

So one other question, I'm buying my friends PDX400.1 alpine amp and was planning on putting it into my WRX, but now I'm thinking since I have alpine speakers maybe I'm better putting it into the s2k. The only reason I wouldn't want to do it is the alpine is a bit more powerful then the jl amp currenlty in the s2k and the wrx I will be also powering a sub so won't be using as many channels for the fronts thus less power to the fronts so having the extra power form the alpine amp may be nice...also its one of the newer wrx hatches so their is a lot of room to fill.

 

Your non-puncutation is a bit tricky to read, so I'll do my best.

Isn't the PDX400.1 a mono subwoofer amp, so won't be any good for driving the Components?

What kit do you have installed in the S2000 at present?

Head Unit:
Amp:
Speakers: SPX-177R

I'd suggest that you probably need more power in the S2000 as it's a noisier environment, especially with the roof down.

 

Oh boy sorry, this is what you get when you send emails for a living all day, and just want to free type as a break.

Both amps are 4 channels, sorry I typed 400.1 but meant 4.100.
