What is the BEST AMP for a dual 4 ohm sub that needs 350 watts rms?

also, whats the best amp company?




let the debate begin!

 

Try Crossfire Car Audio...

They have a VR401 which is a 400x1 in 2 ohms or a VR300D which is 300x1 in 2 ohms. Both amps are rated at 12.5volts. You will get about 15-20% increase at 13.8-14.4 volts.

Den is right cross fire has some good stuff, but this is going to be one those mine is better than your because forums.There is no one answer to the queastion, alot of repetable manufactors with good products out there.

 

:?: How much you wanna spend :?:

 

Cross fire is really good. Make sure it's a class D amp though, much better for subs!!

 

im looking at like, less than 300

 

Crossfire makes good amps but you may also want to check out sounddomain.com and look at the Phoenix Gold Ti series amps. The 400.2 will easily do 400 rms bridged and is on sale around $300! Great deal for a top line PG amp. And sound domain is an internet authorized PG dealer so you will actually have a manufacturer's warranty! Good luck with your tunes!

ok...first...the info that im gonna provide may be shocking to some...but true

you dont need to spend 300 on an amp where u need so little power. get the bazooka el1500, yes bazooka. although it can be bought for around 150, this amp is outstanding. i used to run this to two 4ohm alpine type r's and my friend has them going to 2 12" kicker L7's. a great amp for the money and it wont bust on u. good luck.

 

Yes eveyone is going to recommend thier fav amp on this, but consider your options from what other have done. To me warranty and rms power rating are the most important to me.

I have a new amp at my shop, made by Diamond Audio. It was new product at CES this year and we have done a handfull of them in the past 2 weeks.

Model is D3600.1 It is a 600 watt RMS at 1 ohm, adn 300 at 2 ohm. I think this would be a good amp because it is totally stable, plus it gives you room to upgrade to 2 dual 4 ohm subs if you want. Amp come with a 3 year warranty and is $350. I haven't seen a whole lot of amp lately that give that kind of service.

Just an idea. I am planning on using at least 1 of these in my car.

Diamond is a very good amp I agree.

I am currently running a 1000watt Hollywood sounds amp in my car. By far I feel this is the best amp I have ever owned and the power is very consistent.

Im running Crosfire subs, I am a HUGE fan of them and there amps. Hollywood sounds and Diamond are at the top of my list as well.

Basically I would stick with the following brands:
Crossfire
Hollywood Sounds
Arc audio
Diamond

 

if your only driving subs
http://cgi.ebay.com/ws/eBayISAPI.dll...category=39737
800rms into 4ohm load
about 1200rms into 2ohm more power then u need to give u a headache with subs that could take it
282 to your door not bad if your on a budget lookin for power

 

Diamond amps are great for any application, true clean power and now more affordale with the D3 series amplifiers. A true clean low distortion amp is gonna cost about a dollar a watt, and just a reminder PG & Diamond to name a few do not authorize online sales in order to protect their dealers so even though they would normally carry a 3 year warranty...whatever website is advertising these amps cant warranty through the manufacturer. Plus the TI amps were on close out not too long ago and thats why they are selling it so cheap.

 

how much will the quality of the amp play in as a factor here? will there be a noticable difference in sound to a relativly green audiophile? (this is my first system i'm building, so naturally i need pointers) If it is so noticably better, then the new mission is to find the lowest price i can get one!

 

i agree - rockford has been around for a while and they are made in the us, i'm using the 400 model and it fine for my 2 12 type r alpines. i'm using hte 801s in my other car and think it is a little extreme.=) but who cares bass is meant to be felt.

 

Best bang for you buck is the JBL BP 600.1 ~220 from sounddomain.

I think $220 is a bit too much for a 600.1, I got my 1200.1 shipped for 235.

But, certainly I do 2nd the JBL comment. You could even go with the 300.1 for quite cheap.

 

Don't be fooled...RF use to be made in US. Not true anymore. Some of there skus are made in the US but the majority is overseas.


It does make a big difference on how it controls the subs. Inexpensive amps will perform sloppy and muddy. Also take note that not all specs are 100% accurate.. When the new CEA rating come out, it will tell a lot about a amp.

 

Den, tell me more about the CEA rating, Some of these amps are rated ILS(if lighting strikes the car). I would love to see some kind of rating system for amplifiers. I am still running A high current Autotek, circa 1993. 88 watts total output. This amo has seen three cars now, It is one of the last made in usa Autotek amps. BUt school me on the CEA rating system, Thanks Bill

 

I've really never investigated the situation but here is press release i found..

It should elimiate a lot of clarifcation of manufactures that rate their amps at 14.4 volts and over 1% T.H.D. We have no problem with this because Crossfire amps are rated at 12.5 volts under 1% thd.

CEA Adopts Rating System for Mobile Audio Amplifiers

July 8, 2003 -- Arlington, Va. - The Consumer Electronics Association (CEA) announced that its Mobile Electronics Committee (R6) has adopted a standard rating system for measuring the performance of mobile audio amplifiers. The new standard, designated CEA-2006 - Testing and Measurement Methods for Mobile Audio Amplifiers, was created to make it easier for consumers to compare technical characteristics that determine the quality of mobile audio amplifiers.
The standard applies to headunits, separate amplifiers and subwoofer amplifiers. Products that comply with CEA-2006 will be authorized to carry a corresponding logo.

"This standard benefits retailers and consumers by providing a logical measurement tool that helps demystify audio," said Pat Lavelle, president and CEO of Audiovox and chairman of CEA's Mobile Electronics division. "The ratings and disclosures provide a consistent, technically reliable resource for consumers to use when making purchase decisions."

"CEA-2006 fills the void that previously existed when consumers needed a uniform measurement method to compare different products," said Ralph Justus, vice president of technology and standards for CEA. "This standard helps clarify product differences, particularly regarding rated power output and distortion, and helps increase consumer confidence about their purchase by helping to educate consumers about the product's benefits."

The primary measurement criteria outlined in CEA-2006 are power output, the signal-to-noise ratio and total harmonic distortion plus noise (THD+N). With the new standard, consumers should expect to see two primary ratings - an amplifier's primary power output in watts (RMS) and the signal-to-noise ratio in dBA. The primary power output in watts is measured at a level with less than one percent THD+N to indicate how much continuous power the amplifier delivers at that low distortion level. The signal-to-noise ratio is measured at a reference level of one watt. A larger signal-to-noise ratio number indicates more desirable audio and less noise in an amplifier's output.

CEA-2006 is available from Global Engineering Documents at http://global.ihs.com. Additional information about CEA's Technology and Standards department can be found at www.ce.org/standards.
