2 12" subs and 1 8" sub will they perform good together?

Hello, I am looking to see if I can wire up a 8 inch Infinity Reference 8-Inch 1,000-Watt with Powerbass 2XL-124D 12" Subwoofer.

My 12's are dual 4ohm but I'm running them parallel/parallel which knocks them both down to 1Ohm and my amp is 1ohm stable and mono. I am planning just to parallel it off one of my 12's.

The reason I am doing this is because I have slot in my charger in the rear dash for an 8inch subwoofer to be installed in.

Is this possible and still get kicking and good bass?

Simple answer is never mix subwoofer sizes/brands/models etc...

Stupid idea....

A pair of dual 4 ohm subs need to have all of the coils wired in parallel to achieve 1 ohms. Adding another sub in parallel lowers the impedance further, below the amp wants to see. If you wired it in series the 12 would get less power and bass output would be less.

The rear deck will rattle like hell if you add a sub in it. The factory sub is weak and pointless.

it may seem that adding another sub would add bass, but sound is complex and the result of your plans would be less bass, equipment damage, and worse sound quality.

Cliffs: don't add an 8

Well thats an easy answer and I was hoping for that. Wasn't looking forward to breaking the seal on my enclosure, I was told likewise by someone about the 8 inch that it would be beneficial but the math doesn't add up Ohms so I kind of figured I'd lose significant power

That pretty much sums it up
