An-i-no

Do you go around jammin stuff in the mid to low 30's? I play a good bit of Bigpimpin91 and DJSNT. Which is all low, 28Hz-38Hz. Well I guess I can't argue with that. No excursion issues at all? Edit: Wait bandpass or standard 4th order ported?

WRONG! Sorry, not trying to talk ish, but this is dead wrong. The reason it is said to set gains with head unit volume at 75% is because your head unit can clip the signal at high volumes before it ever even hits the amps. I personally didn't follow this rule for a long time and paid dearly in abused damaged equipment. I now run my Pioneer at 50 out of 62 for max volume and gained up a little on the amp resulting in a louder and cleaner sound. Can also play lower due to the cleaner signal not heating my coil as much. This is also all on a 600 rms sub with 1500 rms going to it daily with no issues. Like I said, not trying to be a dick, just callin it like I see it. Low volume, PROPER gain is the way to go. And you definitely need an adjustable ssf when tuning and playing that low. Lol seriously? You can have your gains maxed out and run your headunit at volume 1 and nothing will break. You can run your headunit at max volume before clipping and run your amp gains low and nothing will break. Either way is the same? 2x3 = 6. 1x6 = 6. No different with a Hu and an amp? That's the entire purpose OF a gain knob? And the "cleanness" of the signal is not making your sub take more power. 1500 watts is 1500 watts clean or dirty. It may take the power just fine but the quality of the signal has next to nothing to do with why it hasn't melted yet. (not to say that it will melt)

Probably not. There arent many full range mono amps out there AND you would lose all your left/right seperation. A bigass two channel amp would do you good though.

It doesn't matter. Low Volume/High Gain and High Volume/Low Gain is the same thing.

Crap. There goes a nice sub. Don't sweat it bro. Sometimes you learn the hard way. Like the other guy said, make it a habit to watch your subs play, feel the cones for heat, check for any burning smells. It'll teach you a lot just by observing.

And uhmm...If you set your gains with a DMM/O-scope/DD-1, you're pretty much guessing because probably don't drive around playing sine waves and you definitely don't know what levels the music you're playing recorded at so...."max power before clipping" is a DIFFERENT gain knob spot for every song...lol

Damn Kicker amps Ok. So you're subs were taking full power down to 25 Hz? I'm pretty sure that = overexcursion.

Your ssf is NOT at 70hz....at least i hope it isn't The amp has a cross over setting no ssf. If that's true then that's the problem. It's been over its mechanical limits and its broken now.

Your ssf is NOT at 70hz....at least i hope it isn't EDIT: Dammit you mean the lpf is at 70hz. We need to know what your Sub-Sonic Filter is set to? Please tell me you have one?

You're right. I was just playing detective though. As easy as it is to set your ssf, I mean...there's really no reason to have it set wrong

Aw cmon you know they never listen to "you won't be able to hear the difference."

I wonder what kind of amp he has? I mean...he said: "Driving home at night" = headlights on. "Stopped at a red light" = alt not spinning "Turned it up to 25" then later he says "never turned it up that high" = amp asking for more power than it usually does. So I'm thinking he was dropping below tuning without correctly setting the ssf before now, but add in more power (or a little clipping/distortion action, whatever) and you get this.

Well i know it's fine, but i'm wondering if 24 slope would be better. I'm looking at 2 amps and one has a 12 dB and the other has a 24dB so I'm trying to decide which one to get. It's not "better" its just a steeper slope. The sub will roll off quicker with the 24db slope. If you cross it at 80hz, for example, with the 24db slope it will be quieter at 90hz than it would be with the 12db slope. If you want the sub to roll off very quickly then you want the steeper slope. It just depends on what you prefer.

The backseats in the Impala don't fold down?

Shooting for a product for every application I see. All we need now is Component sets and Coaxes.

This. Do as much as you possibly can for free before you go out and spend money. You'd be amazed at how different you can make your system sound.

Growing and growing...sounds good.

*is jealous....*

Holy shit reading fail on my part.

Have you deadened the roof? If not you might not want the sub/port to load off of it cuz it will flex and rattle like crazy and it may or may not cause damage. My rear window would let rain in when I had the port aimed back in my suv. I know you have a truck, but just something to think about. EDIT: It's also easier to build a loading wall when the sub is faced front/back or to the side than it is to build one on the roof.

College kid working nights here.....lol Anyway, most ppl have smartphones these days. It should be fairly accessible for everyone.....

What exactly do you need help with?

My car had a crappy system in it when I got it. Had to slap the radio sometimes to get the front right channel to play lolool. I started reading about car radios, then amps, then subs....then I started buying stuff and it took off from there.

I'm referring to thermal failure. I'm not sure what there is to disagree about, clipping increases average power by 50% to 100% (depending on who you ask) which on turn cam quickly cause a woofeor to go poof. 95honda said himself: "Normalized voltage (AKA amp at full clipping). This shouldn't have been much of a surprise to anyone knowing that a square wave with the same Pk-Pk voltage as a sine will have almost double the power. As you can see on the spreadsheet and graphs, power handling severely dropped when the square wave was applied in this test. Time to failure was cut by a factor of 4 for most drivers. " Julian just posted in his Bcae quote that: "If your speakers are rated for the same power handling as your amplifier is capable of producing cleanly, driving them with a clipped signal for extended periods of time may cause speaker damage and/or premature failure. " I'm only agreeing with what they posted so how can you agree with them and not me?
