[QUOTE="Jeffdachef, post: 8717785, member: 650438"] Ported does not equal sloppy bass. Prefab ported boxes is sloppy bass, you know the ones you buy on ebay or amazon, all garbage and will sound like garbage. Seeing as you have a 2009 corolla i know the acoustics of the corolla very well since i had one. You will not get any kind of deep bass with a sealed box because the vehicle resonant frequency is very high in the 47hz range and sealed boxes will always peak high, you have no means to fix this issue in the frequency response at all. Which is why you need a custom ported box designed properly for bandwidth and sound quality. You'd want a lower tune to flatten out the frequency response along with having a box with good group delay(accuracy) which can be controlled which people dont understand and have huge misconceptions about ported boxes. For your trunk though, you only have space for two 12s. Again, build that ported box and do a proper two 12s setup and have a proper amp to power it. As for your amps for 3 12s. You can just run a single amp as long as you are wired above 1 ohm, you are good. so three dual 4 ohm subs wired in series parallel would be 2.66 ohms, you are fine, while three dual 4 ohm subs wired in parallel would be 0.66 ohms which is only fine for korean amps known to handle half ohm loads along with you having electricals to back it up. three dual 2 ohm subs wired in series parallel would be 1.33 ohms which is completely fine for most monoblocks. Always have one amp, not multiple, Gain matching and getting the phase correct with multiple amps will screw your output over vs having a single amp. [/QUOTE]
