I really want to do 4 18" lvl 4 DC's. You may ask why lvl 4? they are lower power and are rated 1000rms. My plan was to go 4 lvl 4's and a single Soundstream xxx 4000d. I know it's not exactly 4k at 1ohm. But I don't have the cash to really spend on a nice amp. But I was gunna fund this project by getting rid of my almost new mayhem and mint RUB2500 for 3 blown lvl 4's. Not it doesn't matter if they have upgrades or different coils. Cuz I'll recone them to be all the same as needed. I know I'll have to beef up my power supply,but not like I would as if I was going to run 4 mayhems. and I have already designed a box to fit in my SUV, tuned to 28hz. It would be a cheaper more simple build, I'm not really getting to fancy with it. But after this build, I'll prolly be done for a while. but my question was, is this ok? Practical? Any ideas or feedback to help me out?
