As most of you know, i was planning to go with a Concept Amp but after installing, was a major dissapoitment. So, can yall give me suggestions on an amp that is 1 ohm stable and can feed my 13.5" W7 2000+ watts rms of clean power. I am willing to Spend between 500-700. Have fun with this topic but i NEED your help experts.

Two JBL 1200.1's...one per coil and it just happens have one for sale But you may not want to run two amps on one sub daily. Also a US Amps 2000x is a good possibility.

i am curious as to what the details of the install are. what kind of battery, alternator, woofer enclosure, power wire. it all seems a little strange to me. all of the jl w7 that i have heard sound good and tend to get loud, for sq........i dont quite think it is an amp problem.

i'm with killarbb and brodequin here...how did you manage 0.8 ohms with a single sub that has 3 ohm coils? And please, no namecalling, no smack-talking, just straight facts...i know you get defensive and type things which you really shouldn't at times, but just answer these questions. I think your amp is fine and you have a problem elsewhere...

Sorry man you didn't like your amp. However, COncept has been daaaaaaaaaaaaaaaamn good to be so far. Those numbers you see below are with only 50 sq inches of port. That amp is beautiful, powerful, and efficient. Maybe your load was off? Hit me up on e-mail if you interested in a buyer for the 2400a...... Posts: 4564 | From: Carolinas, USA | Registered: Sep 1999

#2- I would recomend using a JL 1000/1 or large 1000-2000 watt class a/b amp for your W7. No dirty nasty class D power for the wonderful W7
that clears up #1
#2...if he can't power a 2000W class D amp, how's he gonna power a 2000W Class AB amp even if it is only slightly less efficient (the AB that is). I still say there's an install problem...
was that a concept 2400 or a concept 2400a? i know they had power supply problems (some doing 1800W, some doing 2200W, etc) on the 2400 but it should still have enough gusto to push that W7

hehe, someone beat me to it. that's what im using on my w7 in a sealed enclosure and the w7 is still craving for more power at 3ohms mono. but then again, my stock elec. system isn't giving the amp enough juice

JBL per coil would be a good idea but if you want cheap & somewhat powerfull
a pair of used D300HC amps off ebay thats alot of power for about 750-850
I personally rather have the cleaner more powerfull D300HCs which should only be about 200.00-250.00 more moneys.

Alright, I have the W7 in a sealed 1" thick MDF box built to JL Specs by Bobby Gately. I have 2 gauge wire runnin throughout the system. Stock everything with a batcap 400. i had to turn the volume damn near half way up to get the sub bumpin, that wway to high IMO. With my perfects, half way woulda been so loud. Anyways, What about the Autotek Mean Machine 5000 for power. Its class X it says on their website, anyone got more info??? thanks

class x...what's so special about the circuit technology. Prob just marketing...
how old were your perfects? The newer perfects didn't like alot of power and hence got off easily...also, how were your gains set on the amp (you never answered if it was a 2400 or a 2400a...)? What kind of box were your perfects in? if this has already been discussed THOROUGHLY in another post please link me...i'm not sayin the amp can't be bad, just sayin i find it a lil hard to believe that amp couldn't push that sub. where did you get the amp anyway? if something is wrong why dont you send it back for warranty? If your W7 didn't work right the first time would you sell it and replace it too?

Why buy such a great sub and then not be able to feed it?
No offense to you or anything. But this is a general question I have. I don't understand why some people buy top notch gear some places in their system, only to go the cheap route on another part.
Your system is only as good as your weakest link. Granted that equipment is only half the battle, install being the rest, but still.
Get yourself a good clean amp.

my amp was the 2400A model and what do you mean by cheap amp. the amp retailed for over $1000 off SD and had some pretty good reviews. i think autotek is a good small company that makes a good product. anyone ever have any bad experience with autotek products???

KJ this is very true
I think all he was saying JG is that if your going to spend close to $1k on a sub you should spend twice that on the amp, but that's just something I was told a long time ago. and for an SQ first sub like that I would go with a clean class D or a high-po class AB

jl's recommended specs are "recommended" and that doesn't always mean that it'll suit the type of application that you'd want---this is coming from my experience from also owning a gately 13w7 1" mdf enclosure.
whats the EXACT size of the box you're using? i wouldn't change amps all of a sudden--- in my experience the 13w7 likes an enclosure size between 2.5-3.0 before displacement for optimum efficiency and great overall transient response. i'm guessing that he built you a smallish 1.8 which you would definitely need a lot more power to get the w7 moving.

kick the idea of this amp OUT of your head because they do there power @2ohm mono..you have a 13w7 which are dual 1.5ohm coils, so unless you are getting a pair of these, theyll do you no good..and for anything other then burps i doubt the w7 could handle the juice of 2 of those
2000x with a good electrical system

this is what the autotek website has to say about the mean machine 5000 being a class "x" amp.
"A new alternative to Class-D that offers much cleaner operation (Lower Distortion) in Low Frequencies with it's new Digital to Analog Filtering. These amplifiers incorporate very high efficiency MOSFET controlled Power Supplies and Audio output Transistors, requiring less power from your vehicle to produce high energy. They are MEAN Beasts infused with heavy-duty power distribution busses and a heavy cross-section heat sink. Delivers Deep Clean Bass. "
so what do yall think
