Sundown & Rainbow Together

[crea78 0]

I recently just purchased a set of Rainbow Germaniums (150w RMS) and a Profi 12" subwoofer (DVC 2ohm - 50~350w RMS). Currently I have eD amps in my car (9.2 & 9.1) and I've heard alot of great things about Sundown amps. The SAX-100.4 caught my eye after seeing pictures of it, but not sure if it's gonna work with my setup. If I run Channels 1-2 to my Germaniums and have Channels 3-4 to my sub (needs to be 2ohm if possible), would this be a possible setup?? I know the Germaniums will not get the power it needs @ 100x2, but if I bridged the 100.4, then that is way too much power for them. Also, how many watts will the Profi sub be getting if I bridged the rear channels?

My system is still a work-in-progress, so not sure how I want to power my speakers...

Or I guess the best thing to do would get a SAX-100.2 to run the Germaniums and a SAE-1000D to run the Profi 12" @ 2ohm. That might be the best setup. Just wondering if the Sundown amps will be an upgrade coming from eD amps??

Use your judgment You don't have to be an expert to see the difference here.

As for the SAE-1000D to the NINE.1 -- the NINE.1 is actually a more powerful amplifier, so swapping here doesn't make as much sense.

sundownz, looking at both amps internals, the SAX-100.2 does seem to look alot better than the NINe.2. Also, do you think using a 100.4 biamped would be a good route to go with the Germaniums? Right now I have the Profi sub running at 2ohms from the NINe.1 (gains set accordingly). I know that is 300w more than the SAE-1000D, but I don't need that much power for my current setup + I like to change things up a bit as well.

I am a huge fan of bi-amping, and I feel that you would love the results This will give you much more flexibility to fine tune the crossover point and the tweeter level. I would say go for it 100% if it's in your budget.

i would say also that switchinf your sub amp wouldn't really give you a noticeable gain. if you're concerned with the power just turn the gain down a little bit. and can some explain exactly what biamping is lol. i think i know what it is but i want to be sure.

There's a like-new 100.2 for sale right now.

bi amping is using 2 amplifiers on each set of components, one would be for the tweeters, one for the mids. The passive crossovers on some component sets will allow that to happen.

that's what i thought. you could technically use a four chanel to do the front stage that way as well then right??

i dont know about the germainiums but my older profi's cant be biamped.

though iirc the 100.4 can bandpass the rear. in which case you could run active. if so i would definately do that. you would gain back the power lost from the passives. just be careful not to pop a tweeter

active control = yummy

Yes.

I recall that channels 1&2 may be HP from 50Hz-5kHz and LP from 30Hz-250Hz, making it suitable for your treble section. Channels 3&4 may be HP from 50Hz-1kHz and LP from 50Hz-5kHz, thus making it quite suitable for your midrange/midbass (yes, the HP and LP combination allows you to bandpass the midrange). Wonderful flexibility.
