    :word: I think if you needed a diagram for figuring those thingsout, you'd just get cross-eyed using that one :crazy:

    It really helps a lot for those who wanted to modify their audio system. I just also wanted to share some basic relationship between the resistance which is the unit for resistor (ohms) and power which is (watts). sometimes they are directly proportional depending to what application your into. So taking consideration to their proportionality, we can say that if we increase the resistance in the connection of the circuit the higher the power. we also need to check the impedance matching of the speaker to amplifier, so that they function well.

    one thing that i didn't see here is mono amps and single subs.. Am i correct in my assumption that to run a single sub with dual 4ohm voice coils, i would run it parallel to the mono amp for a 2ohm load?

    Alright, hopefully I can ask here... I'm looking at some upgrade component door speakers for my 02 sierra with the factory radio... should I be looking at speakers with 2 or 4 ohm impedence?

    Anyone here know the output specs of the oe delco radio off the top of their heads?

    I may possibly get a slightly better head unit one day, but I dont want to accidentally end up with some component speakers tha only sound good when amped... looking at some infinity kappas which say they are good with factory radios, but also saw some CDT audio classic speakers on sale but they are 4ohm...
    and of course I still only have fctory speaker wire...

    So, if I want to put in 2 subs on my 200w 4oHm fosgate amp I'd want 4ohm, DVC subs to keep the lowest distortion rating... right?

    to bridge amp... amp neg right (or left... depending on the amp specs) to sub1 neg1, sub1 pos1 to sub1 neg2, sub1 pos1 to sub2 neg1, sub2 pos1 to sub2 neg2, sub2 pos2 to amp pos left (or right depending on the amp specs)


    This crap always confused me. I used to have 6 DVC subs in a wall.. all in series/parallel who knows... to 1 HCCA 225 amp. They said they swore the ohm load was under 1/4. Didn't understand then, don't today!

    I have 2 4ohm subs hooked up to a 1000 watt 2 channel 1ohm stable amp. My question is one of my subs went out and now the other sounds like junk. I know 1 is obviously going to sound different than 2. Is it because the ohm load changed just curious?

    Im so stupid at this so i need to ask if this will work because im getting lost. A single 12" scv 4 ohm sub and a 2-channel 4 ohm stable 820w bridged amp??

    Okay this was really helpful :head3:
    Can someone verify my plans are correct.

    Amp: Cresendo BC3500D (stable to .5ohm)
    Subs: (4) Sundown SA8v2 D2
    1ohm goal
    Is this correct wiring?
