anyone use this stuff i was thinking about getting some for my box. THere are good reviews on crutchfield but I dont know for sure. They claim it makes the sound louder or tighter or some how better. Well if you have used it give me your personal opinion

well i know its bigger than the minimum of 1.5 feet but i also know that it cant possibly be the max which is 6ft. I guess i answered my own question im gonna go to a craft store and stuff it it when i try to mount it in better this weekend. Probably get a sound meter from radioshack although i hear there not right on the dot but ill see what the db difference is if it goes up at all with the same song.

that stuff is expensive and unless i had some kinda proof i doubt i will try it. The poly-fil is cheaper and ive heard its been used in speaker boxes.

 

well got the sound level meter and guess what....Doesnt go hi enough it averages 111-116db but when i turn up the bass boost and hu it went to the max 126db now i just relized theres two different settings for different frequncies so im not sure if i had it on the right one. Does that seem good for a Kicker 2000watt 15" ran of a kicker *x1500 running 1750 watts sealed box? well its night time now so i cant try the other setting but i did this with the windows and doors closed then set it on my chair toward the sub but not directly by it.

Well went to my local Micheals craft store and picked up some poly-fil. I was very pleased with its outcome. I didnt get much DB increase but it did go up 2 db on two different songs at a regular listening level it was at about 113db. I put about 2 and 3/4 pounds of poly-fil in my box with the 15" and it cleaned up the sound its much tighter now. I wasnt to sure about it but im very happy with the outcome. If anyone has a sealed box id say definetly give this a try. I was having alot of rattling of my box so i had the bass turned to about 1/4 now i can put it all the way up and it sounds clean. I wouldnt say you need that stuff ment for speaker boxes because this stuff for $2.49 a bag 1lb 4oz works great. Anyways just thought everyone in Radio and sound would like to know the outcome was great and im very satisfied with the way my sub performs.

I'm not an expert but my understanding of using fill is that it helps when the box is too small. I added a custom box to the Yukon between the rear captain chairs. Too small a space to make it proper for the sub. Filled the box with fiberglass insulation from Lowe's. Sub hits pretty hard.

Yah it does make it hit harder. I probably had the minimum or close to its air space for my 15" thats why i did it and because it didnt cost much to test it out. Good to hear another person has tried it and liked the outcome

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
