[QUOTE="manooti, post: 8265801, member: 661188"] Before we begin, please dont flame me for being a budgeteer [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] Installed Power Acoustik Gothic 4500d (dont say it lol) and 2 NVX NVS124 subs (dual coil 4 ohm, 350rms) in sealed box. I think the brand of box was bass(something).. PA says amp does 2700x1@1ohm. I know its probably not near that at all, but one can only hope lol. I'm guessing it does around 1500 with the 120A fusing. Anyway, I was expecting it to sound less than what it is it which is a plus given the price to performance ratio. Using 0GA cabling from front to back and ground as well. Now, the gain issue and maybe distortion. I used the DMM method to adjust gains for 1ohm@ 1200rms for the subs. I do think it might be overpowering too much. Gain is close to half way mark with SSF off, LPF to max, BB off, and with tone of 49hz@ -5db 3/4 max volume on Pioneer deck with 2v outputs. Subout set to max for tuning. DMM VAC@ 34 steady if that means anything When I play music there is crazy rattling going on. I'm not sure if it is the subs being overpowered while not being broken in yet or my panels that I ended up dropping the clips inside the frame of car [IMG]//content.invisioncic.com/y282845/emoticons/rage.gif.0ad8a6e5565b5fddce406566fdd05149.gif[/IMG] Forgot to mention, with Loudness off on radio I had almost no bass.
