Message: [QUOTE="jdc753, post: 124127, member: 52"] The CVT's have gotten great reviews through the years compared to all the other shallow subs, but their large volume needs seem to contradict the use of a shallow sub. Looks like you got a few things to fix, some more internal volume for the sub, keep it from hitting the back seat and maybe double check your amps settings. The wiring and impedence of the subwoofer is what will dictate the impedence the amp see's and not how the amp is wired. I am assuming the sub is a single 4ohm, if it was single 2ohm it will send the amp into protection when the volume gets turned up even slightly while the amp is bridged, since it is only 4ohm stable when bridged. With that amp bridged to a single 4ohm sub then the sub should be seeing 560W with the gains set correctly and at max (listening) volume. Now you have the low pass filter on, but what is the crossover point set at, if its pretty low you won't be letting the sub play enough of the frequency range, around 100hz should be a good start. Also what head unit are you running? Does it have a subwoofer level feature? Could be that the level is turned down in the HU or that the EQ settings are cutting the low frequencies out of the signal. [/QUOTE]
