speaker box math help

[sur3fir3]

When I competed I had Orion components in the doors, loved them. I've never had orion amp before. A choice between them I'd have to go JL for sq or sq+ for sure but its not just the equipment it's placement also. Almost anything can sound good to the human ear if done right but not so much to an analyzer.

As far as handling power any speaker can handle more than its Max, as long as its a clean signal, this goes especially for quality speakers. Its always better to over power as opposed to under power a speaker. The distortion is typically what kills a speaker, or the voice coil burning up for getting too carried away with wattage. I've seen subs catch on fire....OK it was mine lol.

Remember PPI before they went all SPL? Specifically the art series. Man those had a beautiful warm sound, clean as can be. I miss the old days where quality came before quantity and all the companies sold out. I met Alma gates once in Florida at an event and we talked about that and where the industry was headed lol, how cool is that! That was when she took over kicker and rocked the spl record with the ugly bronco lol. I miss the old stuff, sound stream, ADS, US amps, the "good" fosgate stuff before they commercialized. Not the same anymore.

I can't believe someone here remembers alma and her bronco damn thing had cement in the doors lol. anyone remember the old cerwin vega stroker series? now those were some subs

Crazy subs indeed, but please tell me you have components and an amp for them too... If there's one thing I hate its all sub and no freakin minds or highs lol.

he bought my JL audio 300/4 So he has a decent high/mid amp, but he still needs component speakers.

I build for music not just bass. The setup should be loud and clean enough to over power the nothing but bass around here.

Lol yeah that bronco had to be hauled on a trailer due to its weight. Moved at the speed of smell...

Oh yeah I remember the ugly ass strokers lol. Dual spiders, coils, stupid heave and expensive. I saw a video years back where these people put one to the test.... they had some bench mounted amp you could adjust watts I guess to test equipment....they ended up pushing like 30,000 watts into one before it finally gave lol. I forget exact wattage but it was a HUGE number, it may be more than 30k, I'll see if I can find it.

Anyone ever heard of "afterschock" subs? They looked cheap like pyles and were a small brand, didn't last long I guess. I was in a DB drag years back and a kid pulled up a minivan with 2 15's and a single nexus lion amp, he was in the unlimited class so we all laughed at him. Wtf are aftershocks? Paper cones, no name junk...

Wrong! This dude just crushed everyone with 2 generic looking paper subs we never heard of. ......and then everyone bought them lol.

He even beat the Crankenstein pro van that had 12 12's lol. It was unheard of...

Holy crap this may be the dude I saw! A nexus Lion amp in a van with 2 aftershocks. More spl than a stroker or a DD, insane!

there defiantly had some cool stuff coming out in the mid ninety's, I didn't ever really have a chance to play with the Precision audio equipment since the shop i worked at only sold Orion and MTX as their high end models and i was a poor 19 yr old working at a car audio shop. One of the coolest things i seen back then was some pioneer 6x9's that were rated at 500w and with a good clean amp would pound like a set of tens. After I got them hooked up to our display rig and tested them my boss got a call from the jewelry store next door telling him that we had to turn them off because it was shaking stuff off the shelves, I think they were MIP's or something like that.

 

[synnyzter]

hahaha thats awesome! I remember those, circuit shity by me had them and yeah they were loud for a 6x9 lol. A pair of those could be had for $100. Most kids when I was in school had 6x9's since we couldnt afford subs lol. I was so poor in school I took 6 1/2's and built tubes for them and thought I as cool hah.

 

[mayrider]

It's funny that the guy's that are typically installing your system couldn't afford the equipment. I had two 10" MTX blue thunders powered some cheap fosgate knock off, a 1000w(truely probably 400w) amp called the thump, luckly they were behind the seat of my 72 chevy pickup so i didn't need alot of gain.

 

[synnyzter]

Lol I made cent money but only when I did fiberglass opulstry or vinyl work. Basic installs I made crap really. Figure the shop charged $50 for a head unit install and the shop gets a big cut of it and I got the scraps. Custom work is the only money in that job.

I recently had a heck of a time powering 2 5x8's and 6x9's from polk. Head unit would thermal out after about 10 minutes and shut down, bought a 75w (rms) x 4 kenwood amp that would thermal and drop by about 40% volume, tried a MassiveAudio (MA) 4x100w and it would hold for about 35 minutes then thermal.

Got lucky and snagged an old school RF punch 800a4 on ebay and finally was able to drive the speakers to their max without thermaling.

After all that, probably would have been money/effort ahead to just resell the speakers and get something rated a bit lower...

I can't imagine the hassle of dealing with subs again. I don't recall having these issues back in my high school years with a couple kicker 12's bumping off a couple cheap 200w bridged pyramid amps. Then again, I didn't have an hour commute either.

Wow...amp have good ventilation?

Sits on a back deck in a grand marquis with air all around it. Had 6-8" on left to right and 12" from the top of the amp to the top of the trunk:

This is the same spot I put the kenwood and now the RF amp. They "tout" that amp as one that fits into confined spaces... when it thermaled, I touched it and it blistered my finger. Poor little fella got hot!

Regardless, seems like the old RF amp is holding up fine.

The kenwood I tried and RF I now use:

 

[synnyzter]

Ouch yeah too hot lol. Plenty of space tho. I've ran a sound stream sa244 which is 40x4 on those Orion components which were like 100rms and didn't skip a beat. Audio poop is so finicky and random...pain in the ass sometimes. Live and learn I guess like anything else

[olds97_lss]

Yeah... by the time I bought all 3 amps, I was into it for almost $500... for that kind of money, I could have just bought a decent current RF retail! An RF T1000-4AD (250w rms x 4 @4ohms) would have gotten it done in spades I'm sure.

Also paid $150 I think for the install of the cabling. I was way too lazy to do that myself. Was a kicker cabling they used at BB. And they did a shoddy job. Didn't solder a single thing, even on the fat power wires. Just crimped the thin/weak ends on the cable.

At least I didn't have to run it through the car. Just solder everything that wasn't to remove any resistance points.

 

[synnyzter]

Yeah retail chains won't do all that, need a specialty shop. In all things audio it really is worth paying the extra for quality electronics...just like this hobby. You really get what you pay for.

Those were the rockfords I had back in the day. An 1100a2 and 800a2.

 

[olds97_lss]

Yeah, it has plenty of power, but has a bit of a muddy sound to it. The MA amp sounded nice and bright, but even when I tried the kenwood and MA amp bridged to have the MA running my 6x9's and kenwood running my 5x8's, the nano still overheated and shut down at about the same interval it did before. The kenwood took a bit longer to drop volume 40%, but it did.

 

[synnyzter]

Well as I said before over power never under power! Don't be afraid to push a 1000rms sub with 2000 watts, as long as its clean, you'll be safe!

I had these in last Sunday but the alternator doesn't put out enough juice to bring the amp out of protection. Then with the appendicitis everything got put on the back burner. I don't have any trunk space but I rarely drive the car anyway so it doesn't really matter. Box is double walled all the way around. It is 2 separate chambers. Weight with subs is about 240 lbs. Took 4 guys to set it in the car. My alternator is scheduled for delivery on Monday. Hopefully that will put out enough current to pull the amp out of protection and I'll be good to go.

 

[olds97_lss]

Where's the amp?
