Xtant amps

Post by tj80 »

First off.. great forum, the FAQs are great, and I've tried to read as much as I can... but I still have a more subjective type question... I've been swimming in ideas for speakers and amps and subs oh my. I've finally narrowed it down simply due to popular opinion (and cause I thought they sounded good in the store) to Infinity perfects.

I'm looking to build a modest SQ setup, not spend much money (say maybe $500 (ebay pricing) or so for amp, sub and components). I'm not someone who's going to blow stuff up by listening to it at ridiculous volumes... and I don't need a ton of thump. Just nice crisp music, with some nice quality bass. I listen to everything, rock, rap, jazz... you name it. I also need to conserve space

I'm going to run 6.5" components in the front, a 10 or 12 inch infinity sub in a sealed box... all kappa perfect line stuff. On crutchfield, they list the subs as needing 75-350W RMS, and the components needing 25-100W RMS.

Now I'm picking out some amps to go with that. I may or may not add some rear fill, just to keep my back passengers happy... I'm still debating on that one.

So first off, I'm watching these Xtant amps on ebay right now... and they seem like a good deal.. but I don't know if they're enough.

Two main options:

404m 4 channel
50w x 4 @ 4 ohm
200w x 2 @ 4 ohm bridged
100w x 4 @ 2 ohm

2200i 2 channel
100w x 2 @ 4 ohm
400w x 1 @ 4 ohm bridged
200w x 2 @ 2 ohm

So one option I'm considering would be just the 404m. Run the components on 2 channels, and bridge the other two for the sub.

That leaves everything a bit low on power.. 50w for the comps, and 200w for the sub.

Another option would be to get a pair of 2200i's and run the sub bridged on one @ 400w, and the components @100w a piece. The only thing I don't like about that option, is it means a third amp if I ever want to add rear fill to this system. Maybe I don't need that though.

A third option, a 2200i feeding 100w to the comps, and a 404m feeding 50w to the rears and 200w to the sub.

So many options... I know the RIGHT solution is to get a bigger 100w x 4 amp... but these xtants are really cheap.. and it's going to mean that I end up having to drop to a lower line of speakers if I have to spend $300 on an amp. These Xtants seem too good to pass up. Any way to make these fit into what I'm trying to do?

Like I said.. I don't need huge thump, and I don't need huge volume.. I just don't want to rattle my nice speakers apart by underpowering them.

Hope you guys can help me make sense of this..

Honestly all 3 sound like a nice set up. I have always liked Xtant amp, so good choice on the components.

My best peice of advise, figure out how much money you want to spend and go from there. Keep in mind, you can always add another amp later.

That being said, I woud go with the second option. Especially since I am not a big fan of rear fill. That way you have plenty of power, even if you decide to upgrade your speakers later.

Thanks for the input... it's good to know I'm not way off base (bass) with my decisions.

I thought up a fourth option, which I think I may do... Buy a 404m and a 2200i, and run just the sub off the 2200i, and just the components off the 404m.

Bingo... 400watts to the sub, 100 watts to the components.

Then if I want rear fill, I'll just run it from the HU. I'll try it without though, and see if I like the sound. Everyone who knows anything seems to agree that rear fill is bad, unless you're going to spend real money and do it right. (and even then lots don't like it)

So I guess I need to go with popular opinion on that one.. it's just hard to get used to the idea of not having rear speakers...

Thanks again!

I used to be kinda weary of removing my rear speakers. Untill I actually tried it. Now I won't go back.

That set up sounds good, let us know how it turns out (I want pics too)
