Stiff subs or unrealistic expectations?

[QUOTE="T3mpest, post: 8164624, member: 560148"] 2.5v RCA's are not an issue here. I've never seen an amp that couldnt' run on a 2.5v RCA and get full output. RCA's are a preamp signal not an ouput signal so they won't have an effect on the final output of the system. He doesn't need to spend money on a new HU to get his speakers to move. Don't give advice if you don't know what your talking about. Now back to the OP. On the cutout side that is too big do you have an airleak around the subwoofer. You can easily build another baffle on top of the front side to fix that without doing much more work and that might help your output by quite a bit. You want a perfect seal behind your sub. I'd also redo that ground. Make sure it well sanded and if you can find another point I'd do that. You can always make your own if you can find bare sheet metal and drill in a screw. A bad ground could be limiting your amp, but usually it'll go into protect. Last thing I can think is check your wiring. If your accidently wired at a higher impedence that may be a problem also check your HU settings. Low pass around 80hz. Turn High pass on your subs off or at 20-25hz or so. The subwoofer output on a kenwood can be turned up without any issues, it's not a bass boost it will raise the whole bass range equally. I'd turn it up and then reset your gains. [/QUOTE]
