Audio questions
Hey guy, just looking for some clarification on a couple of things.
- if I were to install the cicada 88 DSP for a 4 channel system, but then plumb channels 1,2,3,4 outputs back into 5,6,7,8 inputs giving me 16 parametric EQs instead of the 8. I would leave the second round of HP and LP completely unmolested correct? It would double up the filters making a 12 slope a 24 and so on. Is my understanding correct?
- also, on my amp, if I have 2 sets- 4 ohm speakers on channel 3 and 4 of my amp wired in parallel giving me a 2 ohm load. Basic knowledge would say. 400 watts is 28.2 volts with 2 ohm. But if I actually ohm out the cable to speaker resistance and it’s at a 2.2 for example I should push it to 29.6 for 400 correct?
just looking to get what I can out of my system without screwing up. I have a cheap oscope and dd1 I will make sure it’s not clipping just fyi.

I also have a question. Is this a joke? I've got another question Why? Why would you do this? It makes no sense at all.
Moving on to your 2nd question. No, that's not how it works. A speaker impedance changes with frequency.
Also, if you have a scope and a DD-1 WTF do you need to use a DMM for anyway?
Now, step away from the tools before you hurt something (or someone) and go do some research. Then come back with some serious questions.

Thank you for the knowledge you passed on.
1. no, sorry.
2. I realize it would be a weird path. But it would give 16 bands of para eq on 4 speakers.. correct? I also realize it’s also leaving the opportunity for another failure point and it’s probably overkill. But If you were trying to fine tune it a little more than the 8-10 bands on most DSPs. It’s an average priced dsp. DSI3 is pretty expensive for 31bands. If you did wire it goody like that wouldn’t that be like using dsp filter and then amp filters? which if you did that doubles up the filters right?
3. So I don’t believe every speaker can handle 400 watts. So I guess it’s more of a question on ohms law more than anything. But you did confuse me now. So a 4 ohm speaker according to the manufacture isn’t going to show 4 ohm load on an amplifier?
4. DD1- used to quickly set gains to max via 1k test tone
oscope- used to double check 150,500,3500,5k test tones to make sure there’s no clipping.
DMM- channel leveling when bridging, and Amps can put out more than their specs say. So it’s used to double check what voltages are at.
5. how is my use of electrical tools going to hurt someone? I could hurt some components with a poor setup though. Sorry for the theory questions.

Quit over thinking things and no running 1 or multiple channels in series will not give you more channels of adjustment.
As suggested do ALOT MORE research on parametric EQs
ALWAYS remember the K.I.S.S. method and quit trying to reinvent the wheel or Ohms law.
This bike audio is only as hard to do as you make it out to be
