Help me decide

[CrazyKenKid 64]

Well i need some help choosing my next amp!

here is my future application,

2-15inch NS v1 (already purchased)

2-saz2000(1 of 2 purchased)

1-ID horns

2-nsb 90's

big 3

h/o alt (200amp)

Now my question is either the 50.4 or the 125.2!

I need some help deciding. both amps have pluses and i am leaning towards the 50.4.

So here are the immediate plus i see:

50.4, future application due to the 4channels and resell able

50W x 4CH RMS 4 ohm stereo

80W x 4CH RMS 2 ohm stereo

160W x 2CH 4 ohm bridged

125.2 more power, less $20 lol

125 watts x2 @ 4 ohms

200 watts x2 @ 2 ohms

400 watts x1 @ 4 ohms bridged

Now for the question which would you choose to power a pair of ID Horns?? I am leaning towards the 50.4 b/c if i ever take out my 2-15inch subs i will need a 4channel amp to power all of my speakers and if i ever need to upgrade i would be able to sell a 50.4 a little easier than the 125.2. I don't see any pluses other the 20$ price differences?

so in a nut shell which one and why for a pair of ID Horns?

thanks for your time and input!

p/s i have the money ready to purchase either of them

I would run the 50.4 it is a much better option for future upgrades!! I don't know anyone that dosn't upgrade sooner or later!!

you smell correctly! llol! but this log isn't going to start till about some time after april (when school lets out for the summer)

[CrazyKenKid 64]

so 2 ppl say go with the 50.4!! can i get a 3rd!

[CrazyKenKid 64]

I posted up a poll!

[Lucky 76 5]

I went with the 125.2 for my id horns. I just did not want to have to bridge if it was not necessary. Other than that I would say go with the 50.4.

is bridging bad? or just complicated?

[CrazyKenKid 64]

Hey i just noticed something about the ID Horns they are 8ohm and 30-40rms! wow!

http://www.woofersetc.com/p5004/CD1MH-V3--Image-Dynamics-Reduced-Size-Mini-Horns.htm

so this 50.4 can do 160rms @4ohm 2channel bridged right so at 8ohm what can i expect 80rms? so 40rms to each horn?

does that make sense or should i jsut drop jacob an e-mail?

[Lucky 76 5]

Another reason I went with the 125.2 was it was closer to the power range. You do not want to overpower those tweets believe me. They are great but arent meant to handle more than rated power. I talked to this guy named eric at id and he said you want an amp that will output about 75 watts rms @ 4 ohm. I believe I asked Jacob what he said they put out at 8 ohm and I cant remember what he said. I would ask him again.

Also are you going to be using an active crossover or are you crossing over through the amp?

[Lucky 76 5]

To be honest with you I have no clue if bridging is bad or not. It dosent sound like it can be good though. It just seems like it would take away from the quality of the output. I don't have any clue though ahhaah. I would ask Jacob about that as well and share the info you get ahahaha.

[CrazyKenKid 64]

i think i may just do that! thanks for your input!!

as for setup i think i want to run active and jsut set my amp to handle everything that way i don't have to worry about cross overs and i believe the 50.4 has some killer feature i can set!

[Lucky 76 5]

If you wanted to run the 50.4's internal crossover you would be limited as far as crossover points are concerned. You need to get an active crossover or go with the 125.2.

[CrazyKenKid 64]

i thikn you are trying to convince me to go with a 125.2.... lol!!

but here is another idea with the horns i need a pair of midbass (as i just found out lol )) so if use the 50.4 i could use 50rms to the mids and 50rms to the components! lol! but i would ahve to find an active crossover you say. any suggestions off hand?

[Lucky 76 5]

You might want to step your game up and go for the 100.4. Then you can set your crossovers without an active crossover and save you money in the long run. Not to mention you would be able to get adequate wattage to the mids =)

[CrazyKenKid 64]

so what you are saying is if i was going to run a 100.4 and a pair of horns/mids the 100.4 would be ideal? b/c i would be able to use the very nice crossover that the 100.4 has?

[Lucky 76 5]

mmmmyesss

[CrazyKenKid 64]

issue solved! thankyou SOOOO much lucky 76! i was lucky you were on to help me out and to see another option i didnt' even think about!!

you rock man! thanks so much!!

and thread closed BTW!!

Just contact Jacob and ask him about the crossovers. I am pretty sure the 100.4 is flexible enough for you to set the crossovers for the horns and midbasses. Just specify the frequencies you wish to put to them (1.2khz and above to the horns and [50-80hz]-1.2khz to the midbasses) =)

Glad I could help

I have a 50.4 bridges to my comp set, and I like it a lot. It was cheaper than the 125.2, that's why I took one !

I think the amp crossovers are usefull when you're on the 4 ch mode.

On a bridged mode, you just use the HPF, no bandpass available.

4 x 50 w per channel , and 2 x 160 watts bridged : how can it be like that ? Isn't it a 100 x 2 amp ?

My Focal 165 KP seem to handle all the power from that amp, and they're rated for 80 watts rms.

The 100.4 is maybe a better choice for you.

just my 2 cts

[CrazyKenKid 64]

I just got a reply back from Jacob regarding the 100.4 and using it to power the horns and a midbass driver! here was his reply!

Yes it can bandpass one set of channels and high pass the other -- no problem. Use the subsonic as the HPF portion of the band-pass. - Jacob

so problem solved and thanks for everyone input! esspecially Lucky 76
