My system doesn't pound, but it hit's like around the 130 mark. 2 10 inch hx2's with the Rockford P8002. I'm in the process of upgrading, I bought the system, because I was on a budget. I Don't think it sound's half bad for a budget system.
On the other hand, I've sat in a guy's truck who had an unbelieveable system. Don't know the exact db, but it was close to 160 I think! When he turned it up, it actually took your breath away! It was like someone was squeezing your whole body. This was in a Ranger single cab. 4 audiobahn 12's with 1000 watt's to each sub. The funny thing is, he was going to add another 2 12's in his truck. I know audiobahn isn't the best, but that was the loudest truck I've seen around heer.
The reading was on an old mic not the new kind that they use. I think it was louder with the windows down. I just want it louder so im going to add another 1501d. Unfortunately 200 amp alternator is the biggest I can find. I want it to feel like a hard punch in the back. I WANT LOUDER. Any suggestions?
not bragging. i expected my windows to flex or break. hunter you hope to hit 145 with one twelve!! If you can do that with one twelve then i should be able to do 148ish with one 15". Thats what i want. I heard of single 12"'s doing 150. Do i have the wrong subs? What will be louder?
its all the install, my friend. i higher tuned box...like 50 to 65 hertz, not too big of a box, im going to run 2.5 cubes. lots of sounddeadener, the right box. and you need the electrical system to be up to poar to draw full power. ive seen a single 12w7 hit 150 once, it was in a jeep larado.
you gotta love those dhds, they supply the right amount of heat to make system s hit, in fact mine can do tricks, i call it the "FLAMETHROWER" never seen an amp throw flames except this one. this one guy told me that his tru hammer was better then mine. i told him your full of sh!t and i hope you die.......i hate it when people dint know the quality of my stuff. any way this amp does 1000 WATTS at 24 v...o...l...t...s(voice trails off)189.19er aint too bad for dhd.
He was joking....lol. He does hold a world record, though. Lucas, you can shorten the port, but when you do that, you'll also make the net volume of the sub larger, so you'll have to find a compromise. For max SPL you need to tune near the resonant frequency of the cabin, typically in the 60s-70s. 28hz is a very good SQ tune, and if you're happy with that, then stick with it. If you want more SPL while still having respectable SQ, mid 30s will do well. Once you approach 40s and above it gets more one-notish and boomy sounding. The reason people tune higher is because it results in higher SPLs, due to both cabin gain and the fact that less power and excursion is required to produce the SPL at that frequency.
I hit 148 with my two 12 inch sony xplods hooked up to my 300 watt xplod amp. in a 3.5 cu. ft. ported box.
RadioShack's meter goes up to 135. The official meter of USACi, DB Drag, MECA, and SLAP is the "TermLab" sound pressure level sensor. It can be purchased for around $600 from Wayne Harris at www.termpro.com I have one, works very well and is very consistent.
(btw, I used DigitalDesigns 9512's with MMats 3000.05's at world finals this year, did a little over 160 for first place. There was some confusion as too wether or not I was over qualified for superstock since I owned a shop, so I have since switched to pro stock. Although I am the current World Champion in 901-1800 SuperStock, I have relinquished my record in the superstock class for this reason. This was my first year competing and it was apparent I had a slight edge, the previous record was 151 and I posted a 157.8. So, I have now began running 0-1000 pro stock, three weeks ago I ran it in Mempis TN and posted a 159.5. At this years finals 157.2 won that class, so my 159.5 isnt so bad. In the first week of march I will be at S. Padre Island Spring Break Jam attempting another world record, this one in Pro Stock wish me luck. btw, world records are set with a B&K microphone set in the legal position sealed on the dash, any other time vehicles are metered in the kick panel outlaw/door or window open. That is why world record numbers are lower than outlaw numbers)
actually i found three of the mmats amps on the streets and as far as the shop i had no insurance so it really hurt the business. the guy who broke in here murdered a guy on the other side of town last week. before that i was thinking about going to whoop his azz since the cops couldnt arrest him for breaking into the shop, but now i'm glad i didnt, i could've gotten shot. anywho, nice to see your still around here. ttyl bro
