I bought a pair of

Pioneer Premiers (650 RMS each )

I got an amp with them but I haven't a clue how many watts its putting out.

Can a person test the amp some how with a multimeter?

It says on the amp the model number A275HC. The brand is audiobahn.

I've looked online a ton but still haven't found a very definite answer.   The subs are hooked up to create a 1 ohm load.   They sound ok but I'm just wondering how I could figure this out.

Thanks a ton,

Mark

some amps have their specs on the inside covers of there amps. others dont and audiobahn is out of bizz so lack of online info may be the reason for this.

Yeah I was sad to see that they didn't even have a website that I could look any specs up on :/

I'm not sure how I would take the cover off. I'll try that though. Any info would be helpful.    

So I take it there isn't anyway to check to see how many watts the amp is putting out?

Are there fuses on the side of the amp...?

!!! Wow Thanks a ton Tommy!!! Where on earth did you find those specs???!?

I'm thinking I should get a different amp for my subs...?

I was trying ti figure out how to measure the watts it was putting out earlier today with a volt meter using some equations but had no success.

I definitely need to readjust my gain, etc.

The model # of the subs are: TSW2000SPL

Here's a link to a review of them: Caraudiomag.com review

I bought them from a guy who had them in 1cf each box sealed.   I'm currently waiting on a new box to be delivered to me in a few days thats 1.5cf each chamber, sealed, and carpeted :)

I'm looking to push around 600RMS or a little less to each sub.

I also have a 475a - Infinity 4 Channel Full-Range Amplifier
It's not the best amp in the world ( the s/n is like 86db) but it works. I'm pushing a set of infinity kappa perfects 6.1 and a set of infinity kappa perfect 6 x 9s with it.

My main concern if I get a bigger amp for my subs is that I'm going to need to get a new alternator. Well that and the fact that I'll have to replace my 4guage power with 0/1

Yeah i found that website too, vibrationcustom but i couldn't find this amp on that website so it wasn't any help.

My car is a 88' Caprice Classic :P She's a freakin boat.

My HU is a Pioneer DEH-P4800MP

Well I'd like to get a good amp but I'm not here to spend 500+ bucks seeing as I only paid 200 for the pair of subs and the amp I have right now ( got them off a guy that got a new car and didn't have the space to put them in his car / his gf wouldn't let him have them anymore )

Here's one of the amps I was looking at https://www.online/CarAudio/ProductDetail.aspx?Productid=20598

yeah I know that. If can make things work with what you got but save some money up to upgrade someday. I liked audiobahn for the longest time until they started putting out crap and went to re audio (love them) and then upgrade again with what I got now. I might get 2 more amps and 2 more 12s and Im done upgrading at least my audio speakers. But like I said just save and something will come your way.

Oh ya you link did not work for the amp.

Is this a ebay kinda of thing ...Or brand new...? Memphis , JL is usually a safe bet...I sell alot of Kenwood amps w/ minimal problems...The blurb below is from kenwoods website...!

The X1200M ($500 suggested retail price) is Kenwood’s most powerful mobile power amplifier ever built. With Class D rated power at 800 watts (RMS) at 4 ohms, 1,200 watts (RMS) at 2 ohms and a maximum power rating of 2,400 watts, the X1200M is stable at 1-ohm operation making it the choice for extreme power output.   Dual Sigma Drive circuitry is used to improve the amplifier’s damping factor which means more control over subwoofers. A continuously variable low pass filter (50Hz to 200Hz) helps to tune the subwoofer system for maximum output, while a variable infrasonic filter (15Hz to 40Hz) cuts low frequency output at the point where it is not audible, increasing amplifier efficiency and lowering distortion. A preamp-level output on the X1200M allows for the addition of multiple amplifiers and ensures equally-matched crossover points and input levels. An optional remote bass control (KCA-WR10, $50 suggested retail price) can operate the volume of the X1200M from the driver’s seat and will provide up to +18dB of bass boost as desired (bass frequency is variable from 40Hz to 100Hz).

Ops. sorry tommy.   I didn't realize my link didn't work.

Hifonics BXI 1210

There's the correct link.   It runs @ 1ohm Stable...

I was talking to a car nut though and he said that if you are running stuff at 1ohm that your amp's headroom will be bad and that your amp will get really hot / sound quality will go way down.




Posted By: tommy...
Date Posted: July 20, 2009 at 5:22 PM
For life of all equipment...I would stick w/ 2-4 ohm whatever your options are...Are they dual voice coil...? what is the Impedance(ohm) of each coil...?

So ... what is bad about wiring at 1 ohm..?   Could someone list the cons and pros...?

Also since it's a two channel amp could I wire it up differently?

I need some amp suggestions.. I'm pretty lost :o

The link you posted is to a 1 channel amplifier.  It has 2 positive and 2 negative speaker wires, but it is only a 1 channel amp.  The terminals are connected together inside the amp.   They say that the amp is capable of operating at 1 Ohm.  The lower the Ohm load, the harder the amp works.  That amp is not cheap to repair.  When they break, they break big.   Running it at 2 Ohms will make it last longer.  DO NOT MOUNT IT TO A SUB ENCLOSURE.

Did i miss the subs specs...? Yes,i agree w/ I am an Idiot...! I think you will be more then happy w/ the 2ohm load...! 1 year warranty, just have to pay shipping(and back if it needs repair)...As long as you dont mind the internet service...Go ahead...Im sure you will be fine...And i have no clue on normal pricing on that stuff...But call some local dealers and see if they can come close/match that price...I always say when someone asks if i can match an internet price...Can they match our service...!?

Just curious, why you suggest not mounting it to the sub enclosure. I bought the subs from a buddy, he's the one that mounted the amp to the enclosure, not me.

Could you explain / try to help me understand why it has two possitive and two negative ? Also... are you talking about the Hifonics or the amp i have right now?




Posted By: tommy...
Date Posted: July 22, 2009 at 5:25 PM
It is WIRED inside amp...They are just nice and give you 2 outputs instead of the common 1 set of outputs(mono amp)...He is talking about the Hifonics Amp is expensive to fix out of warranty...That is why he suggested to run it @ 2ohm... Oh and the reason not to mount it to the box is for vibration...!

Oh and i am an idiot, I didn't even look to see that there was two sets of + and minus inputs.   So it's just so you can wire stuff up easier...?   / what is the advantage? / what would I use the second set for? just wondering.   

Instead of running it at 2ohm and only putting 450RMS to each sub should I get a different amp that puts out 1200RMS at 2ohms?

Someone else suggested that I get two amps and run each sub separately.

Would a 2 channel amp even be something to look at in this instance?




Posted By: tommy...
Date Posted: July 23, 2009 at 8:45 AM
Are you trying to be as loud as possible...? Im thinking you will be more then happy w/ the Brutus @2ohm... Unless we are getting closer and closer to the $500 mark...?

No, I'm not looking to be loud as possible, I'm just looking for preferably one amp instead of two. ( Hence the two channel option..?

The reason for the two channel is so that I can run both subs at 2 ohms instead of having to buy an amp that would push them well at 4 ohms.

Bumping since dead period was all weekend.

Update: I talked with a "car audio installer" at one of the car shops out of town ( went to a bigger city ).

I asked him what his thought was about running stuff at 1 ohm and he said he does it to all his stuff.... He also suggested using slot vented boxes and to practically never use a sealed box.   He also said that an A/B amp will pull as much power as a Class D amp....   Isn't he slightly incorrect here....?

Thanks,

Mark

I wouldnt call him a liar, at the same time I wouldnt second his opinion. I recommend class D for subs when asked, but I run a 4 chan amp to a single 12" personally. Its possible to run both those Pioneers with that amp, but not probable to find a recommendation to do so. Thats the way the cookie crumbles....

^ ^ That was a pretty funny thread you are refering to.

So.... will running a two channel a/b amp work...?

(has two 50amp fuses in it.)

Yes , Running a 2 channel will work...But i think a Class D is more Efficient...The 2nd set of outputs on the amp,like in most situations, a sub box has 2 terminal cups and you can run a lead to each cup...If you have multiple subs...Etc...!

Yeah I know Class D is more effiecient..:/   I'm gna test my luck with a high end A/B amp for the hell of it.

LOL...After re-reading...That was kinda tough...! Basically i was saying that in most situations , there are 4 wires running from sub box...(one set from each terminal cup)...In other situations ,if you have multiple subs...It gives you a 2nd set of outputs...(instead of daisy chaining)...Why are you going w/ a "high end" class a/b...The actual reason...?(availibility...price...recommendation...?)
