Anyone know the best amp for 2 audiobahn 15" eternals??

this amp would work wire the subs parallel for a net 1 ohm load
anthony90 on 06/26/2007 17:35:20
In parallel, @ 1 ohm, wouldnt that be alittle more than the subs could handle - they are only 1,300 rms??/
kirchatndftbl on 06/26/2007 17:48:00
both subs together are 2600rms which is the amps rated output at 1 ohm
anthony90 on 06/26/2007 18:40:29
Disregaurd my previous statement lol.. I dont really know alot about all this, but i'd like to learn - I guess im trying to get into the whole audio genre...thanks dude
anthony90 on 06/26/2007 20:08:22
*Another question - the subs are rated 4 ohm stable, so why would I drop the resistance to 1 ohm? Why would it not be better to find an amp that was 4 ohm stable?? Sorry for all the "rookie" questions but I dont really understand some of this
anthony90 on 06/26/2007 20:10:45
And with those subs - and the Hifonics amp with the right enclosure, Is there a ball park figure of what db that would be pushing??
Bass_bass_10 on 06/26/2007 20:12:38
I'm a rookie too lmao but the lower ohm you can make it the better, by putting it to 1 ohm you are like doubling the power of the amp compared to 4 ohm.. duno if u get what i mean lol so i'll let one of the pro's answer it for u
Bass_bass_10 on 06/26/2007 20:13:46
acctually its more like trippling the power
4 ohms: 850 watts x 1 chan.
2 ohms: 1700 watts x 1 chan.
1 ohm: 2600 watts x 1 chan.
see how the watts increase as the ohms decrease
anthony90 on 06/26/2007 20:18:02
Ahhh I see...So depending on the way you can wire your subs, decreasing the resistance makes it "easier" for the wattage to reach the subs..
Bass_bass_10 on 06/26/2007 20:20:54
never thought of it like that :P but sounds right to me lol :D told u im a rookie lmao.. nice system by the way^.. puts mine to shame lol

I havent actually bought anything yet - Im trying to figure out what would be best for my $$$$'s I've been in Iraq for 10 months - with nothing to spend my money on, so I decided to make an old hobby more serious lol...I've had 2 of audiobahn's 15" lower class subs (AW151T) before - and was very pleased with the sound. Now I want to step it up a notch and see what kinda of db's I can come up with now
Bass_bass_10 on 06/26/2007 20:32:31
nice.. do you know around how many db's you reached with the old setup? i am trying to figure out what i am reaching.. probably only like 100 at the most lol even tho ive spent over $1000 cdn.. shoulda waited before i jumped into things
anthony90 on 06/26/2007 20:54:52
No, I dont know for sure - but I wanna say it was at least 120 or so...Im trying to take my time, and get the best buy, for the biggest boom..What do you have exaclty?

The Brutus amp mentioned is a monster and it will require very expensive electrical upgrades to keep up with that amp. The current draw on this amp will be well over 200A's of juice at full power, into a 1 ohm load.
If your truck has a HD trailer towing package, the stock ALT is typically 140A's at peak power, ~80A's at idle. If you use an amp of this magnitude and don't run it real hard for more than 15-20 minutes at a crack, the stock ALT may survive a few months.
When guys really want to wang their system hard for long periods of time, the ante goes up considerably. (H.O. ALT ~300A, 1-2 high reserve batteries and wiring upgrades under the hood as well) This mod package will set you back about $500.00 or a tad more. Dare I say this is a budget buster already, not including the subs?
Take a look at your original post. I gave some info on a product line called PowerBass. They are new to the US market and have some pretty solid products at well below market prices. The package is comprised of high efficiency Dual 15 subs and a 1000 RMS amp. This amp is strong, but will not require major electrical upgrades. Since the subs are so efficient with power, no need for huge power hogging amps to get them up to well over 130dB of bass SPL.
FYI: The gear used in a given system is about 20% of the net results. The system design and install techniques are close to 80% of the end results.
A side note, have been in this board for about 8 years now. Have helped a lot of folks with tight or fat budgets to get above average results. Yes, I have seen many great products that performed poorly due to bad install and design issues. Have also seen low budget systems that worked very well when set up properly. It's all about getting the details right. (Am not bragging here either. I just like this hobby and watching others succeed)
Just as you served us in Iraq, I too serve others here at CK. Welcome to our family and enjoy the learning process.

i have a mtx thunder TC4001 powering two 12" JBL GTO1202D ^ :(

Today was my first day on this site, and just by reading all the artilcles and comments that you have posted I can clearly see that you a very knowledgable in the field of car audio, and your advice is greatly appreciated..Im not gonna jump in to buying anything before I have the chance educate myself on all the available options..
My truck does have a towing package - but i may need to start thinking about an upgraded altenator anyway because of the abuse its already been through...Just to be safe
swez on 06/26/2007 21:43:15
Thank you for the kudos and yes, I try to stay current with the technology that has changed a good deal in the past 2-3 years.
We also have a few very talented installers and custom fabricators on this site as well. They have not weighed in on your posts yet, but the guys who have, are learning the ropes fast. SMILE
Would I be a bit presumptive by not recommending Bahn gear for your new install? Bahn systems are not as reliable as their price tag and name brand recognition suggests. Have seen a lot of Bahn users come to the board for problems with their gear in the past few years. Some were due to abuse on the users part, while others are signs of quality defects from the Mfg. Either way, Bahn gear is not up to the standards of their peers and up and coming players will be eating their lunch rapidly as well.
As for power management, the simplest upgrades to start with would be:
1. Big 3 wiring upgrade
http://www.clubknowledge.com/cgi-bin/car_audio_faq/faq.cgi?g3481
2. A H.O. battery kit (Optima or Kinetiks, 800 - 1000 CCA rated should do the job)
3. The last option is adding a H.O. ALT to your ride. Don't even consider Power Stiffening Caps as they are a total waste of money and do not deliver the good as promised.
Power Caps are a myth and a bad marketing ploy. The best they can do, is manage minor light dimming problems. They cannot solve cronic and/or severe power supply shortfall that are common to most large bass systems. (Basically, this is a very poor bandaid approach and they just don't measure up to a strong battery kit and adequate wiring)

Thanks for the link - I've never even thought about the "big 3" before, but it really does make sense..Why have a nice big 2 gauge wire when all its gonna do before it completes it's circuit back to the battery is go through a little tiny wire on the negative on the battery lol...So - the use of a capactor doesnt help that much huh?
swez on 06/26/2007 22:33:26
Yes, the Big 3 wiring upgrade makes a lot of sense when we look at most stock wiring used. A #4 gage is a common choice as the wires are short under the hood. This will handle over 100A's of current flow, but in huge systems, many drop to 1/0 wire. (300 A's + rated)
Finding #2 gage wire is a bit harder these days. Many just drop right to 1/0 gage for virtually no voltage drops from the battery to the amp, even at 20 + foot runs. If the amp cannot accomodate 1/0 gage into the power lugs, one can use conversion hardware, (A Distribution Block) that will handle 1/0 on the input side and a short length of #4 to the amp.
Caps are not as helpful as Marketeers want us to believe. The guy who designed and made the original Surge Power Caps, (Richard Clark and Associates) have recanted their claims to some degree. Clark is a brilliant engineer in many respects and he deserves good regard for his knowledge.
But when the Surge Cap was field tested for many years, most found them lacking and not living up to the claims. It took a long time and lots of pressure to make him back down. (Big Ego guy here, but he's still brilliant) Go figure huh?

having been a victim of the audiobahn mystique,let me throw my few cents in, cause i am lucky to have any sense,lol,bad pun sorry, but i gotta agree there are definately better amps and subs for the money, dont let the chrome fool ya, i am on the lower end of the knowledge scale but you will get some great advice if you stick around. good luck and thanks.
