memphis pr1000.1 and alpine type r not hitting certain notes.

[nategearing42]

Hey guys, first off thanks for looking. I just bought an older memphis pr1000.1 amp and an older alpine type r 12 (silver model 500 rms) Anyway, the sub is dual 4 ohm and i have it wired down to 2 ohms. (amp does 600rms at 2 ohms). The box is ported and 1.85 cu. I drive a 1998 mustang gt and sub and port is facing trunk. This thing SLAMS around 40 hz, but other than that i can barely hear anything. its like night and day, it doesnt make any sense. Any suggestions why? Anything is appreciated.

Also, im thinking about upgrading to either a soundqubed hds 12 or an american bass xfl 12. My amp does 1000 rms at 1 ohm. I know the hds is 1200 rms and the xfl is 1000 rms but what would give me more output in the 1.85 cu box? Any input is appreciated. Also, i have owned the soundqubed hdc315 and was pretty impressed. Thanks!

Both of those will want over 2 cubes net.

Check your SS filter

I dont have the room for 2 cubes haha, you shouldve saw me trying to fit this box in my trunk. It was a struggle. My Subsoninc filter is set about 28 hz. with the size box i have which sub would you prefer? Also im pretty sure this box is too big for the type R so could that have anything to do with it?

What's your box tuned at?

I'm not sure. It's an obcon prefab box. I've had an obcon box with two kicker cvrs before and didnt notice an issue with those.
