Xenon 1200 watts to one sub. How do I do this?

Post by Fallen1 »

Hey PGP, I got my hands on a Xenon 1200.1 that needed repair. Got it running and I love it. I'm a little confused though, and would really appreciate some help. I'm pushing 2 Type R12's. I know this is a 1200.1 mono wired parallel internally with two sets of speaker terminals. I'm sure they do this because most people will want to run two subs. The amp powers my subs nicely, but I want to go higher and run two xenons, each one pushing 1200 watts to its own sub. Not my r12's, going to upgrade to higher powered subs. But how do I get that power? When I hook just one r12 up, it is loud. When I hook up both, they are each just as loud. So, there is 600 watts each sub. I want that 1200 watts on one sub. I've come to the conclusion that I can get a dvc 1200 watt rms sub (600 watt each coil). Is that the only way to use all that power on just one sub? The setup sounds great, but I was a little disappointed. I designed and built a ported box (dual sub, split chambers, 1.8 cf per chamber, dual L vent slot vents, tuned to 32 hz). Was very loud, made my windshield flex in and out quite a bit. But that bone crushing bass hit was gone. So I built two sealed boxes (one for each sub, .85cf per sub) and got that bass hit I wanted, with the loss of some loudness. My disappointment comes from this- back in the day a buddy of mine was running two infinity kappas in a custom box in his celica altrac turbo (hatchback) on a 1000 watt mono (don't remember the make, but he always bought high end stuff so I must have been a true 1000 watts). When I was in it, he would turn it up and the world around me would look like it was shaking because my eyeballs would be shaking so hard. I have also experienced this with two jl audio 12w0's in a custom sealed box, hooked up to a pg x100.2, when I would sit in front of it in my room. Now, in my car, that phenomenon is hard to get. Sealed, my eyes shake to the point things look like theyre vibrating. Ported, no. So, that's the goal I have, and I want it. Next stop after that will be a system so loud that it's hard to breathe.
So, my fellow forum members, any advice?
Thanks in advance.

Xenons run full power at 1 2 or 4 ohms. That pretty much covers all subs VC configs. Unless you have an 8ohm sub it should run full power with one sub.

1200 to a single sub vs 600x2 to two subs is only a 3 decibel difference. While that's technically "double" the output, humans hear on a logarithmic scale, so it won't sound nearly twice as loud.

As Nutxo said, it's basically foolproof as long as the sub is at 4 ohms or below.

If your subs are dual 4 ohm, wire the coils in parallel, or run a wire from each terminal to a single coil. If they are dual 2 ohm, you can run either series or parallel, but series wiring (4 ohm final load) will be more efficient for the same power.

Thanks for the input guys. I thought about running in series with a 4 ohm final load, but haven't done so yet. I currently have my subs posted on cl for sale or trade. Going to change to a couple 1200 watt subs. Like sundown, or planet audio BB12D. I'll run them both off this amp, then work on getting a second Xenon and then run a Xenon 1200.1 to each sub. That oughta be a little loud >:]
It's sad actually.....All this power coming from my trunk, still running stock speakers everywhere else, straight off the deck. I can't even hear the other speakers, the bass drowns it out. If I wanna actually listen to my music I have to turn my remote rca input level knob down to 1/3. I think I'm going to track down a xenon x100.4 again and run that to some decent 6x9's and 6.5's. Definately need to offset the bass.

the power rating on speakers is one of the more useless ratings in all honestly. Even swapping to a different sub with a different ohm rating will still net you the same power out of the amp.
what else can I say I am a grumpy asshole most of the time.

Well, I'm gonna sell my type r 12's here locally, and pick up something 1000+ watts on ebay. I want phoenix gold subs but I can't afford that. I had to let a couple xenon 12's go on ebay. 255 for the pair was the final bid, and 250 was all I could do. Sad. It's ok, cuz if I did score them I would've missed out on the two deals I did get-
xenon x100.4 $65 inc. shipping- powers up, no sound. Should be able to fix that and run my fronts.
tantrum 1200.1 $50 locally- driving one day and it died. Never attempted repair, comes with endcaps. I've fixed a couple smaller tantrums, rebuilding this one should be worth it.
Both components will go nicely with my xenon mono. Figure 1200 mono on each sub, xenon quad on the fronts oughta sound pretty good. Not bad for a cooks' wages ;)
What I would really like to do is run a couple xenon monos to my subs (one day hope to be titanium 12's), and xenon quad on the fronts, with the amps all trimmed up and displayed pretty, accented with blue led lighting. Then maybe I'll be happy for a day or two, lol.

So, I don't mean to offend, this being a phoenix phorum, but what budget high excursion subs (spl focused, sealed prefered due to driving a toyota echo but can build another ported also) would do these amps a little justice while I dig around for some decent phoenix subs?
I'm talking two subs, $400 range for the pair. Been looking at a few (orion, planet audio BB, etc) but still can't decide.
I mean, on paper these type r's looked good, so I sold my jl's and got them... but they suck bad. My jl audio 12w0v2's could almost keep up on a tantrum 500.2 and make your eyes shake. I nearly cried when I built a 1.8 cf/chamber L vent ported box tuned to 32 hz pushed by a xenon 1200.1 mono just to hear it be so much louder it was nearly ridiculous, but no eye-shaking, no ears hurting. Where's the punch? Even built two sealed .85 cf boxes and was even more disappointed. I eventually looked deeper into the specs and learned that mechanically these are sq subs, regardless of the common belief and specs. The xmax, the tightness, everything makes these subs work against the output of the amp.
Anyway, any advise is greatly appreciated. Just need something cheap but more teeth shattering for subs while I save up and search for some awesome phoenix subs.
Thanks everyone!
