So, I managed to clip the amp driving my CSS SDX15 and it wasn't even that loud , I might try EQ'ing the lower frequency's out.

Re: iNuke NU1000 Fuse blow on second use NO SPEAKERS CONNECTED

With these cheap amps, I always buy twice the power I need to ensure that wont happen. If you have a house curve dialled in, then it will probably be better eq'ing flat instead. If your already aiming flat, then cutting the low end will make the sub under perform and I would look at returning the amp and swapping it for a higher powered model.

Out of interest, how are you wired up, is the amp running bridged?

Re: iNuke NU1000 Fuse blow on second use NO SPEAKERS CONNECTED

I was running one coil per channel in Mono but Haven't tried it very loud in bridged, All of these tests are just the driver sitting on carpet on its side. I'm hoping it sounds much louder in my 22" sealed cube that I am building atm.

I might try and upgrade the amp if I am still having Clipping issues once it is in the box, I also am not sure if my AVR's subwoofer pre out will be loud enough directly in the amp as I was using a friends Minidisc recorder that has RCA in and balanced +4dbu XLR out. It also has a really loud hum which I need to figure out how to stop.

First impressions with my Sub+amp are not very good
I was expecting better from this amp, I will try it in the box once it is finished (ready to sand and go for a dry fit)

It shouldnt clip at all if your running in free air. However, you state you run one coil per channel in mono, which doesnt quite add up. The amp should be running in stereo if you are connected to both channels. If your bridging then the driver should be connected to the bridging terminals only.

Re: iNuke NU1000 Fuse blow on second use NO SPEAKERS CONNECTED

As in One input plugged into "channel A" and then the setting on "mono" so both channels get that signal from "Channel A" When I bridged I used 1+ for pos and 2+ for neg as instructed by the back of the amplifier. I am really confused because it wasn't even that loud it was -17DB on my receiver and it sounded reasonably balanced (as in speakers to subwoofer levels). It Was not even close to Xmax (from looks).

BTW: Should it sound much better once in the box?

It will sound totally different once in a box. The big worry though is that is should run very easily with little effort in free air. Once in a box it will take more power to get it to run hard. Doesnt sound to positive at the minute but until its in its box we wont know for sure.

Hmm, Hopefully I don't have to upgrade the Amp.

Would running the VC's in series and bridged be easier for the amp to run than the two coils straight into each channel?

I really can't believe that a 1000w (peak) amp is clipping at similar levels to using my old Sony SA-W10G



It might of just been the song that I was playing: Simian Mobile Disco - Audacity of huge, I will try it again tomorrow

Install the driver in the cabinet, run the amp bridged, and see how it goes.
