Amp chosing advice???

I know you guys are probably tired of being asked this, but ok...
I want to get a good SQ amp that pushes 300W RMS and has a range knob from 20-400Hz... not 20-200Hz like some... it will be powering one twelve, what do you guys suggest???

Umm... what is the impedence... you wont be going past 200 on any sub. I am almost certain of that. I would suggest a nine.2 off the top of my head or a mcintosh if you have that kinda money.

and has a range knob from 20-400Hz... not 20-200Hz like some...


wtf for?
Your sub shouldn't be playing above 100hz anyway

so the 20-200hz is the lpf right? what would be a good place to put it at? 50hz? 80hz? i jus wuna know, i realize that the higher u put it, the more bass it has

Ok, well, sr20... I told you about my old system, well, I had a Jensen 300W and it blew out, so I've borrowed a Sony Xplod. The Jensen was set @ 400Hz while the Sony only goes up to 200Hz, and Believe me it sounded way better w/ the Jensen, don't get me wrong, the Sony hits harder (it's about 400W) but sounds even crappier. Since Jensen and Xplod are both utter crap, the only variable in this equation that made the first amp sound better was the higher setting... did I expalin it right

dude, get a midbass driver. you will easily blow out your subwoofer trying to run it too high. The sub is not meant to handle that frequency. You need to set it at 120 at the highest and 80 is the norm.

but then Y did it sound BETTER w/ the Jensen @400 than w/ the Sony now at 200??

If you get a dedicated midbass, which is apparently what you were trying to use your jensen for, it will sound better, but your jensen probably died because of its missuse.

wow, setting the crossover freq higher will blow the sub .... I guess you learn something everyday :rofl:

as for why one amp seems to hit harder than another, there could be at least a dozen different reasons.

well unless u are happy with your sub playing all your midbass, then get good components, and set the sub's lpf to under 100hz, i duno many people that listen to their subs over 200hz, i mean any higher then its midbass, and your speakers should cover that, your subwoofer is made for LOW FREQUENCIES, if u have it turn that high, u might as well throw away your speakers and use your subwoofer for everything in your car, give it atleast 15khz yea?

Since they generally distort at the higher frequencies and draw the amp into clipping easier by spreading out the power more, wouldn't that help in blowing the speaker?

Ok, so can someone give me some ideas on an amp fitting my criteria, it will be powering one kicker 12 and most likely a JL W3 in the future

two subs, not going to happen up to 400hz, the amp I recommended earlier will power one sub

i think he means he might upgrade to the w3 sometime in the future

www.edesignaudio.com (http://www.edesignaudio.com) if you hurry you can pick up a nine.2 at a good low cost

does that fit my criteria??

You do have internet don't you? I sent you a link for a reason.

Haibane ..... distortion does not blow speaker, excess power does. Generally speaking, higher frequencies take less power to play. You would never put a 1000 watt amp on a tweeter. However, if you are playing music with a LOT of bass and midbass, it might add a little extra to the load on the speaker. Usually it just makes for poor midbass.

Subs are just not meant to play that high, their response gets peaky and erratic generally, and it can sound kind of funky. Not only that, but you can actually hear your midbass coming from the sub behind you, I'm not sure about you, but that just sounds bad to me. It won't blow the sub, there's no extra distortion (atleast not in the signal, since the sub can't effectively play that high it can sound muddy though, which could be called "distortion" I guess), it just won't sound pretty, especially if you open your trunk and listen to the sub itself up close and personal while you have it crossed that high.

Well, w/ the Jensen I had the knob all the way to 400 and it sounded fine, of course, it's a Jensen... anyway, sr20, got any suggestions for a 300RMS amp w/ good SQ?

What impedence do you need again? I can't remember if it's 2ohm or 4ohm

I don't know the impedence on the kicker, but eventually I'll have a JL or similar, so impediance @4ohms... I just really need to get rid of this sony amp because it sounds Soooooooo bad!!
