confused about balanced input amps

[husker77 10+ year member]

op' what speaker(s) do you plan to run 8kw through, anyways?

2 eclipse 15" titanium subs. I was hoping to get a 3rd one but I didn't so might only need 5kw or so.

what amps are you looking at so far?

22.6V peak, 45V p-p. Picky, picky, I know... still above the typical 14V p-p HU speaker level.

this also assumes the outputs are truly capable of that RMS voltage. i don't often see outputs that are RMS rated. 45V p-p out of a head unit is asking a helluva lot of a power supply.

the manual does not state the voltage rating just says 8V and 16V. 8V p-p and 16V p-p is much more likely. has someone here put this HU on a scope to verify?

most of the HU's i've put on the scope were lucky to achieve rated pre-out voltage at p-p.

Nothing really yet, since I can't find what I'm looking for I will probably stay with my pair of eclipse da7232 amps. They are rated at like 1000rms x 2 each.

If someone would have the equipment and want to do it, I might be willing to send them my hu. If they are a reliable upstanding member of the board.

a thing of beauty and hard to find..

is this what you meant by 4 RCA inputs?

I have 2.

No. I'm not quite that ignorant, the output ones are to "daisy chain" your amps. But I assume that is what it would look like if I could find something, just both being inputs.. Not sure why eclipse never made amps to match their hu outputs.

i apologize for testing your ignoranage..lol...but no, I have never seen an amp that would accept the inputs straight from that Eclipse...It is a unique approach to eliminating patch cable interferences by recombining the signals near the amp location, which leaves very little unbalanced patch to be contaminated...but makes a rat nest of rca's that befuddled many a installer. like I say, another Japanese trick, I tell ya!

I have the ability to test this.

I have the ability to test this.

Do you want to?

i apologize for testing your ignoranage..lol...

My ignorance is tested and verified on a daily basis, ever since I was married 17 yrs ago!
