Are you suggesting I just clamp it? Didn't you just say that wasn't accurate either? So how in the hell do people test these amps then? Oscope and meters or what? I honestly always thought you just used a meter and a scope and watch for a clipped signal and plug the numbers and get your answer am I wrong? Ow and I don't have a scope so I can't do it myself and I don't even think the local audio shop has one.

I looked throught tons of pages just to see if I could find anything relating to either of my amps and didn't see a thing. I did see where they tested the synergy wtf1.5 and some sundown stuff but nothing on my JL or crescendo 3500. And yes I know it makes no audible difference if it did 1200 or 1500 I just wanted to know cause I'm on the fence about buying another HD1200 for my second sub or just switch out them for the crescendo BC 3500. If they both do exactly what they say then it probably wouldn't be any difference either way. I would assume 2400 watts of JL power would be real close to a crescendo bc3500 at 1.5ohm. Could I atleast get a opinion on if it was you guys what you would do.

If it's a stupid question to you just don't answer. Not all of us are pros and we gotta start somewhere and make mistakes to learn. Did I post in the expert section or something? I honestly was just curious how much the amp dyno'd compared to my crescendo 3500. But no sweat I will figure it out on my own.

Ow and feel free to block me boot me I honestly could give a flying fuck. Only answers you get here are little smart ass comments so what's the point? No wonder in all of the world there is like 12 people on here.

Your about a pucking smartass. I asked a simple question in as nice a way as I could and you reply I should think. If thinking could answer my question I wouldn't even have asked. Don't worry dick head I want ask anything else. You are what's wrong with the bass head community you can't just comment or not comment you gotta act like your the uppity expert and where all stupid just for asking. How can Arron be so polite and helpful and you be such a dick and stay employed or in business. I own a business and even if a customer asked me a dumb question which they do sometimes I wouldn't reply by demeaning them that's just not good business.

I just watched a video of a guy clamping a amp and comparing it to the amp dyno and it was dead on so what's the actual problem with it if you don't mind me asking?

Really, so why do pro's even buy and use them? Do they just not know better. Almost hard to believe they aren't accurate at testing voltage and frequencie. They gotta be pretty close cause every amp I have seen tested did close to rated and some better or worse depending on the brand. Like the zapco, sundowns etc did slightly over and some of the cheaper stuff did a lot less. You sure this ain't just bad blood between you guys and tony?

Yes I know it doesn't show real world, in car on music results, but it does give you a base line on sign waves, to compare it to other amps. And I pretty much knew it does rated I was just curios if they did anymore.

Has anyone ever seen a JL audio HD1200/1 amp dyno'd. I'm just curious as to what kind of power they actually produce. Seems like every other amp in existence has been tested except the HD and slash 1200's. I'm guessing but I would think they do slightly over rated like 1250watts just curious if anyone has tested them or knows for sure.

I think ssa is having trouble with their server, but don't quote me on that but I think that's what somebody posted. I know last week it kicked me off and it took me a couple of days to remember my password and I tried resetting it but it would not work and I tried several times but it never sent a email. And yes I checked spam, garbage, and every other folder but it never came through but luckily I remembered it.

Some high end sq guys use the alpine 800 with the seperate crossover controller to make a double din they stack them. It looks like you have 2 head units but they sound awesome and have a ton of control. But they are pricey like $800 I think.

Yes you need the same size battery's or the weaker one will drain the stronger battery. And I always hook up my amps to the battery in the trunk that way you have shorter runs of wire for maximum power. And you always want to have it secured or other wise it could make contact with some metal and catch fire. Myself I ran one hot wire from my front battery to the rear and grounded my 2nd battery in the trunk with the same grounding point as my amp. But I also ran 2 grounds for my amp as JL recommended. Now my 2 battery's aren't identical but they are they are very similar in size and I haven't had the first problem. You also want to fuse both ends of your hot wire and also have a fuse between your rear battery and your amp other wise you could short out and have a real problem on your hand.

Perfect timing I was just about to build a box for my 2 JL13w7's and order some second skin for my trunk. Just did the doors a few days ago.

^ See when I clean out all the dead hookers from my trunk the 6 cubic foot box and 2 tiny amps will fit. Lol

Just went to you tube and saw a VW Passat with a 6' cubic foot ported box in the trunk and yea it's a big box but that's ok I wanna use every inch anyways to fit my box. But I will definetly have to build it in place to get any where near 6 foot. It's ok if it's slightly smaller as JL only recommends 2.3 anyways as long as the tuning is correct.

I have a 13.5 cubic foot trunk so yea it will be tight if it even fits but I'm gonna use every inch for the box. Like I said the trunk openings are small so I may have to build it in place to use all the available space.

I don't know man I think my chrome Helo's are as good as anything out there. I constantly get complement's on them. I know there are wheels that cost more but I actually picked them cause I loved the look. Can't beat black car with chrome wheels.

Are those helo wheels on that blazer? I have the chrome helo 844's on my avenger they look very similar to yours just chrome with black ascents instead of solid black. And nice system by the way bet that thing gets crazy loud.

Well I used a box calculator and 3 cubes and 33hz was the best for spl I could get on the graph. That's after displacement and bracing.

Looks like I'm going with 3 cubic feet tuned to 33hz. According to the program that seems to be my best middle ground. Loud but still musical.

Fair enough.

I already did my man several times I said I wanted more output (spl). And the reason I said obvious reasons is I have heard they do it to give their subs greater power handling and make it seem as though they do best in small enclosures to sell more units. You answered one of my questions you said that wasn't based in fact so can I assume their recommendations are actually for optimal output while still sounding decent. I do know they say the spec ported box will gain 3-4db over the sealed box. Now all I need to know is will a larger then recommended yield more output and make better use of the power I have available. Doesn't have to be an exact mathematic equation just a ballpark guess would be fine.

All I asked is, if manufacturers suggest smaller boxes for obvious reasons or if it was just a rumor or is it in fact better to build a little bit bigger to get more output and make more of your available power. Doesn't seem to be a impossible question to answer. I was mostly looking for some advice from somebody more knowledgable then me.

I wasn't talking about you jcarter I was referring to M5's comment about JL posted its specs for people like me and how I was unwilling to even try when I litterely just agreed and said yes I'm gonna plug the numbers and see. Dude just sounds like he loathes me cause I wouldn't toss $500 worth of equipment in the garbage and go buy a active front stage when he suggested it.

Yes that's the plan street legal, but I was just asking if anybody had first hand experience with the w7's and knew if the JL specs where best for output (spl) or if I would get a better number from going bigger. I know fat box has a spl box that some say hits like crazy but there is no way to get the specs without buying the $600 box. Just thought somebody on here could give me some insight no big deal though I will figure it out myself. Maybe if I was asking a question about my crescendo amps and sundown subs I would get a little better answer on this site. Probably the JL hate I'm getting. Lol
