2 10's and 2 12's

edit - I recommend building 2 seperate boxes for the 4 subs with each having shared chamber and 1 slot port"People with mullets live 40% longer"   - Ricky Bobby

i might try that. i have started to dampen it allready. i was thinking of putting a 6" sub where each rear speaker is for the mid bass or leave the 6x9's for that. but i have started to dampin

First off, do not incorporate two different sized woofers in a sub system, you are asking for problems, regardless of how you setup crossovers, as you will need a fairly complex and expensive one. Simply not worth it.

Secondly, just recommending a ported box to some one with out knowing what type of speakers are going to be used is foolish. That could end you up in the same situation. The wrong enclosure for the speakers.

How about specific model number for these speakers, and then a box recommnedation will follow. Obviously some speakers fair better in sealed enclosures while others are designed for ported applications.

I am not necessarily against ported enclosures (as it will depend on the speaker) but I find sealed enclosures to have more advantages, like a better over all tonal response with less peaks at certain frequencies, easier to construct, smaller, and less likely to destroy drviers, although thats more dependant on the user.

are you advising agenst using 6 inch woffers for mid bass? and i am not sure wich models yet. ether infinity REF1052W or rockford p1 1os

I forgot to mention that I recommend using 4 subs of the same size (if you are still going with 4). I meant to say that in my earlier post but forgot. I have nothing against using 6" subs for your midrange. in fact I am doing that exact same thing in my car except I moved the location from the rear deck to the rear doors. Im using 2 of the JL 6W0s as my midrange drivers. It does a great job. "People with mullets live 40% longer"   - Ricky Bobby

thoes were the ones i am looking at. i am still looking at the 4. i have always liked the sound of a sealed inclsure more is the problem. i might just go with the 12s
