Subject: Audiobahn DUB1200’s + JBL BP100.1 Amp
Date Posted: October 01, 2005 at 11:34 PM

#1.    I used to own a 15" GTi JBL sub and a Audiobahn Alum12Q sub. I hooked both of these up to a BP1200.1. They worked fine for about 6-9 months. I got tired of the constant headlight and int . light dimming os I bought a PowerAcoustik 2 Farad Cap to try to slim down the dimming. Unfortunatly, this ended up screwing me over. Now both subs sound like crap (compared to how the used to). The 15 GTi is the only one that i sitll have hooked up and it's only putting out about half power (i would leave it unhooked, but i have to maintain some kindof bump!). The audiobahn just sounds like crap. Does anyone have any ideas to what could have happend?

#2. I just bought two DUB1200's from a friend for $150 brand new. I'm planning on building a ported box according to the "everyday ported" specs on audiobahns web-site. Does anyone know is the BP1200.1 will be able to put out enough power? Can it handle the stable 1-ohm load these subs require? If so, will it blow them like it did the others? Or did the CAP do the damage? I just need help before i bust four subs in a month period. Any help would be greatly appriciated!

just get rid of the cap and look for a alternator. and if the spec's for the amp don't state 1 ohm stable. its not going to run at 1 ohm with out damaging the amp . you can get 2 ohm loads from that sub 1 or 4 .4 will be much better for SQ

What do you mean "you can get 2 ohm loads from that sub 1 or 4"  So, with two of these subs I can run at either One or Four ohms? The JBL only puts out 600x1 RMS at 4 Ohms... Would that be enough? I ran the GTi and ALUMQ at 3 ohms, cuz they're dual 6, but hte amp doesnt state a 3 ohm stability or anything? I'm just confused!

I might try to sell the JBL sub and amp at school... Does anyone have a price suggestion? All the people i would sell to have no earthly idea what a good/bad price is on car audio, so just some suggestion from an experienced perosn in car audio would be appriciated! I was thinking like $150-200 for amp and same for sub?

Also, if i sell the amp, what is a good amp that at 4 ohms puts out at least 500W RMS to each sub? Will the JBL BP1200.1 that i already have do that?

your amp can run 1 ohm . be sure to buy or build the right box

What kindof power would i be getting at 1 ohm? would each sub get 600W?




Posted By: youngone
Date Posted: October 03, 2005 at 5:46 PM
no probebly a little more than 600 more like 650 or so but that isent much. it is really hard on your amp to run it at 1ohm though its going to heat up like crazy. and for the dimming trash that cap or sell it. the only thing it dose is add db to your system but not worth it. for the dimming you should do the big three. here is a link on how to do that.

I want a new amp, but I want to keep it JBL. Would two BX500.1's or maybe one BPX1100.1 give the subs any more power?




Posted By: Blowntweeters
Date Posted: October 03, 2005 at 8:49 PM
well if you going to get a new amp i would get somthing that produces the power numbers that your looking for at 4 ohms.

Does anyone know if you can runs these subs inverted? If so, what does inverting subs do to SQ?  Better or worse or no difference. I've nevber inverted a sub, but I thought it'd be cool.

In looking for an amp, do i need to look at the ???W X 2 @ 4Ohms or the ????W X 1 @ 4 Ohms?




Posted By: Blowntweeters
Date Posted: October 03, 2005 at 9:20 PM

watts x1 at 4 ohms the reason for this is your subs ,are dual 4 ohm and you will wire them in a series parelell combo to get a 4 ohm load. and inverting the subs won,t effect SQ . but running and at at 4 ohms verses 1 ohm will greatly improve SQ.

So, if i bought the  BPX 1100.1, then i would get RMS Power: 1141W x 1 @ 4 Ohms . So do you divide that by two to get the power to each sub? I just want to make sure the subs get enough power, and my BP1200.1 @ 4ohms only puts out 600 RMS.




Posted By: Blowntweeters
Date Posted: October 04, 2005 at 12:59 AM

the BPX1100.1 would be a good amp to power your subs.  you will get 570 rms to each sub. that will power them just fine. plus running your amp at 4 ohms gives you plenty of head room for those big spans and deep bass drops. and doing the big three upgrade will help your eletrical system more than a cap. you could also get a kinetik battery. www.kinetikaudio.com spendy but worth every penny. what are you going to do for a box? and do  you know how to wire the subs to get a 4 ohm load ?

Yeah, cardomain's wiring diagram showed me how to do that. And, I'm going to get a prof. audio shop to build the box for me. Like I said above, I'd like to Reverse mount one, and keep one ported.





Posted By: Blowntweeters
Date Posted: October 04, 2005 at 11:19 AM

i would suggest have  both your subs the same way. i would go with a slot ported box. and a large one at that . like 2.5 cubes of air space per sub.

Would a GTO1200.1 work? Or maybe the BPX500.1? Or do I need to get the BPX1100.1 for sure?

Also, I'm getting a Nissan SE-R for my graduation this year, and sill a 5 cu. ft. box fit in that??? I've got a 99 Explorer Sport now, so there no problem for the time being, but will the box have to be that big?





Posted By: Blowntweeters
Date Posted: October 04, 2005 at 5:01 PM
the box only has to be big enough to get recommended air space. the GTO 1200.1 will work but you would have to run it at 1 ohm. and that is not going to give you good SQ. you could fit a box that big in  sentra SE-R but you would have to put it together in the trunk. .

What about two REF611A (the infinity amps)

CEA Rated Yes
Power Output 456 watts RMS x 1 channel at 4 ohms and ¡Ü 1% THD + N 657 watts RMS x 1 channel at 2 ohms, 14.4V supply and ¡Ü 1% THD + N
Signal-to-Noise Ratio 70 dBA (reference 1 watt into 4 ohms)
Dynamic Power 761 watts at 2 ohms
Effective Damping Factor 6.336 at 4 ohms
Frequency Response (-3dB) 17Hz - 251Hz
Maximum Input Signal 6V
Maximum Sensitivity 250mV
Output Regulation .179 dB at 4 ohms

Would two of those work? Are the infinity amps worth anything? Or do they suck?

Posted By: Blowntweeters
Date Posted: October 04, 2005 at 10:08 PM
if  he has some of those in his warehouse the HC 600's. go for it all you need is an isolator. and for an amp what do you want ? if you want SPL and don't care about SQ. get a hi fonic's amp from www.ikesound.com for that amp and sub i would'nt pay much . but i know how cheep i can get audio gear online. that jbl sub is a 15" ? i would sell the amp for like $175 and the sub for like $100 or $125. BTW where are you located ?

The sub is a 15" JBL WGTI 800W RMS, 5,000WPeak. It cost me $250 cuz my bro works for JBL! But it still retials, even on ebay for like $399 is what i last saw one at. What is an isolater, and how does it work??? I'm in Nashville, TN. I'm probably gonna end up gettin the BPX1100.1. How did you come up with the 570RMS to each? The Specs say like 350RMS X 2 @ 4ohms.




Posted By: ALPINERANGER
Date Posted: October 04, 2005 at 11:11 PM
The BP1200.1 is 1ohm stable it will run fine at 1ohm. The BPX1100.1 will do at least 1100 watts between 1 and 4 ohms.
Wire the subs at 1 ohm and the bp1200.1 will be fine. Wire them at 4 ohms and you'll want to go with the bpx1100.1

I have used both on a w12gti both are loud. the bpx has a higher dampning factor as well. It sounds cleaner than the bp.

i was going buy the specs you gave of 1141 RMS @ 4 ohms. sell that sub for $400 then. and if your bro works for JBL get a JBL at that runs 1100 or more @ 4 ohms. and an isolater is so the two differant batterys don't make each other discharge. with just the HC 600 kinetik battery and the big 3 wire upgrade.that should solve your eletrical problem. also can you get more than 1 JBL amp for a discounted price ? what H/U are you running ?

Well, my uncle cold all the batteries whole sale at $40 a piece! I was so mad! He has some "Power Source" Batteries laying around. They' look similar to the kinetiks. If I'm ordering tonight... Should i get One BPX1100.1, Two BPX500.1's or Two BPX600.2's and bridge that mofo?




Posted By: Blowntweeters
Date Posted: October 05, 2005 at 7:08 PM
what is the rated RMS power of the BPX 1100.1 @ 4 ohms ? that really sucks about the kinetik battery . i was gonna see if i could buy 2 of them from you. and for the amps if you can get the same power at 4 ohms from the BPX 1100.1 as you would from 2 of the other amps @ 2 ohms i would go with the 1100.1. running at 2 ohms is much better for SQ and your amp componets.

BPX1100.1

1141 watts RMS x 1 channel at 4 ohms,
14.4V supply and ¡Ü 1% THD + N

I'll just get that one. Now, for the box, I dunno what to get? Either Invert both subs (but that wont be as loud at ported), or do a slot port enclosure. Will the SQ be better in the Invert or will it be the same as the slot port? I'm gettin a pro-shop building me a custom box for $150 (basically i can do whatever i want for $150)... ANy idea are welcome!!!





Posted By: Blowntweeters
Date Posted: October 05, 2005 at 9:13 PM
sealed would be the best for SQ. slot ported will be the best for SPL. if you want ot invert the subs i would go with sealed . with those subs i can't see trying to get real great SQ. i would go slot ported my self about 4.5 to 5 cubes i would go no less than 2 cubes per sub. and basiclly the bigger you go the more SPL your going to get. running that amp at 4 ohms is really going to do the most for your SQ.

Sounds like prted it is! Ok, so the final decision is:

JBL BPX1100.1 Amp - 1141 watts RMS x 1 channel at 4 ohms

Audiobahn DUB1200's - 700W RMS Wired in a series/parallel to gte 4 ohm impendence

Slot Prted Box with at least 4 -5 cu.ft.

Thanks for your help... I'll tell ya how it works out when all my stuff gets installed! It takes like 2 weeks for that JBL stuff to get here so I'll have to wait a while... THANKS AGAIN
