Need input on amp

[TopperCNC]

Hi! I am new here, and find the forum really cool. Recently, I got a deal on 2 Audiobahn subs, namely AW1000X (2001 model). They are rated at 600W RMS each, and are DVC 4ohms. Now, I've been lookin for an amp...

I have checked Audiobahn amps, and have found the A12001DT. What do you think about this one? I will gladly consider other brands if you suggest me some.

On a side note, I plan to run the subs all in parallel, to produce a 1ohm load. Given that I want to feed each sub enough power, am I right assuming I need 1200Wx1 RMS to run both subs, or will a 600Wx1 RMS will give both subs 600W (hence the 1ohm load?). I am a little confused about this right now, so I'd appreciate a lil' clearing up.

P.S.: I got a stock 80A alternator. Will it handle that? I am still running a Pioneer 50Wx4 head unit, wired to Pioneer speakers, but no amp on speakers yet.

Thank you!

David

You just started a fire, here come the Audiobahn haters! The mono amp you picked is a good choice, I've heard that amp in action, and it definately puts out the juice.

Thank you for your reply. About Audiobahn haters, well, I take the advice, however, I like to try things myself. I will give them a shot, and at that price, I simply could not pass them up. Here in Canada, we get horrible prices on audio equipment, so when I saw that I immediately sold my crappy old Sherwood 180W 2ch amp... (you get the picture!). Even if many people think Audiobahn sucks or whatever, it will still be a HUGE improvement to me...

Thanx for pointing out to me that the amp I mentioned handles the job quite well. Now, my concern is: will a 1200Wx1 RMS amp be enough for both subs?

Thanx!

yes it will

how much u paying for it?

if it is 1200X1 how you gonna run 2 subs? running both to one channel? im new at somethings.... i know the basics... thanks for replys

Well.. if it's a mono amp there's only one channel you can run the subs on. There's usually 2 speaker outs on a class D mono amp, however. Both speakers will just be recieving the same signal.

Hi again and thanks for replies. About the amp, I found some of them on eBay, around $320~$400. Still undecided between the A1300HCT and the A12001DT...

Both subs are DVC 4ohms, so running them all in parallel would give a 1ohm load, hence the need for a 1ohm stable amp. Since both subs are rated at 600W RMS, I assumed that a 1200W RMS amp would do the job. Correct me if I'm wrong.

I should be receiving my subs soon, still haven't ordered the amp yet. Will keep you posted about installation. Could take a while though, as I need to pile up some dough... hehe.

Thanx!

Im not too cl;ued up on Audiobahn, but if the A1300HCT (high current? Im guessing) is a class a/b, go for the class D as you only have an 80amp alt, as you said so yourself.

This is important. Are your speakers Dual 4 ohm coils or dual 2 ohm coils? If they are 4 ohm coils I would wire the subs in series parallel. That way you can get a 4 ohm bridged amp to run them. The reason I would go with a 4 ohm bridged amp is the distortion. Every time you cut the impedance, you raise the THD(total harmonic distortion). If you run the speaker in series parallel, it will give you a four ohm load( if they are 4 ohm coils. If they are 2 ohm coils I would also wire them in series parallel and get the Eclipse 32430 1100 watt dual mono amp. Its 550 watts x 2 with kick but signal to noise ratio good distortion level and great damping factor; I used to own one and it put out a ridiculous amount of power(more than rated) plenty of power for the audiobahns, plus you can get them on ebay for around 200.00-400.00 dollars, they retail at 1000.00 dollars. Thats what I would push them with. If you have questions, ask away. //content.invisioncic.com/y282845/emoticons/rotflol.gif.b453361716769b8110ddefc85ff03cd2.gif

THD, subwoofer, meh //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Thanx to all who have replied! I have narrowed down my choices to about 4 amps right now... I wanna know what you think.

- Audiobahn A12001DT

- Audiobahn A1300HCT

- HiFonics Brutus BX1500D

- Orion 1200D

I believe these amps to all be 1ohm stable, and to provide me with all the power I need. Remember: both subs are Audiobahn AW1000X, rated at 600W RMS each, DVC 4ohms. I intend on wiring them all in parallel (thus 1ohm load).

Which amp would you choose? Can you suggest others? I know I will probably need to get my alternator rewound, I'll keep the volume down until this gets done. (stock 80A alt on 2002 Hyundai Accent GSi).

Thanx for replies!

P.S.: do you recommend a ported/tuned enclosure or a sealed one? I intend on custom building it to fit my trunk nicely, with carpetry and all.

I would get the Orion 1200D and go ported it will be louder //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Orion has some great amps. A friend of mine has one that ran at a 1/4 Ohm stable... they are great amps..go with orion

 

[Chris Cepeda]

any ppi amps

 

[TopperCNC]

Right now, I'm leaning more and more towards the Orion 1200d. I've never heard of PPI amps before... Are they the Precision Power brand? I saw one on eBay, and the S/N ratio was 115dB, rather high to me (the higher the S/N ratio, the better, isn't it?)

I will further continue my searches and keep you all posted of my finds.

Thanx!
