I am in an electronics trade at my career center and I got my trade teacher to order a 21" sub that is 1,000 watts rms and 2,000 peak. Our best amp is a memphis 1 ohm stable 1,000 watt rms. My problem is with the 21" being 8 ohm, that amp will only put out 200 watts rms for the sub. So my only thought is to use either one or both of the only 2 dual voice coil subs we have to wire in parallel with the 21" to get the load on the amp as close to 1 ohm as possible. The 2 dvc subs are memphis 500 watt peak dual 4 ohm. Is it possible to wire 1 or both of them with the 21" to get a 1ohm load on the amp? Please help me

 

use your electronic trade knowledge of ohms law and how to calculate series and parallel circuits! not rocket science.. Calculate different combinations and see what is best.
Better yet! Learn to think and plan a system before you buy! Why did you buy that 21 inch sub anyway?
