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.
Hey guys. I finally blew my alpine type R 15 after 4 years. Had my alpine mrd m1005 running to it in a sealed enclosure. It was loud and got 141.4 db at a local comp I did just for fun to see how loud I could get. Time for a new 15 to replace it. I'm wondering if anyone knows a good 15" that compares to the type r or better that will run off that 1000 rms nicely. Many of the subs I like seem to be made for ported enclosures. I'm not against ported box but can't afford to have one built right now and I always liked the sound quality from my sealed. I want to go for a ported box in the near future but want a well built one with low port noise and tuned. Does anyone have suggestions for a sub that will run on a sealed enclosure for now nicely but even better in a ported later? I thought about a DD 2500, or American bass TNT or XFL, but it looks like neither do well in a sealed box. I been out of the car audio loop of whats good, so any help is appreciated.
Here is the car itself....
Here is my build log for my 2010 honda civic LX, when I bought this car I started with a pair of Alpine Type-E 10's in a prefab on an Alpine MRP-M500. Then I upgraded the door and rear speakers with Polk Audio DXI650's and an Alpine MRP-F300 which I also use in my current build. After that I moved to an AB XFL 15's on an Audio Technix AT1200.1d.
This log will reflect my current state:
DC Power 180 amp alternator
XS D5100R under the hood
Northstar NSB-AGM24M in the trunk
Audio Technix 1/0 OFC run to the trunk
Knukonceptz 1/0 OFC in the trunk
Sky High Lugs and RCA's
Crscendo RTS-1 tweeters
Alpine-MRP-F300 bridged at 20Vac for 100wrms
Soundqubed HDS312's in a sealed 5.02^3 enclourse(Yes it's too big, fixing it tonight!)
Audio Technix 60mil deadener
Here is the DC power alternator installed, I have recently changed the belt so that it doesn't slip at idle when it's raining anymore. The new belt is 1/4 shorter as the DC pulley is the same size as the factory pulley.
XS Power D5100R with tool maker terminals
Big three upgrade in all Audio Technix silver tinned 1/0 OFC
Now to start ripping all the old stuff out....
Car was really dirty at this point... Summer semester was killing me, but I needed some work on my hobby time.
I really didn't feel like removing the seats and possibly having an air bag light..
Next post will be the install of all the new goods!!
