need some sound advice to pound

Hello guys, I got my 4 12's put in my burban and have my 2 amps running them. Ya it sounds nice but I need more! I currently have 4 12" mtx 7512-44's, and the amp is the mtx 81001. What is something I could get that will really pound? I want to bearlly be able to sit in the burban and have it pound. Any thoughts would be helpfull. I do not want to wall it off though. Thanks everyone. Phillip

what is the enclosure that your are using?. Try the vented enclosure for max dB.K. Venugopal Rao

I have them in porter boxes already

If you want something to pound and have the money to spend, I would go with 2 Orion HCCA 15.4 subs. Bridge them to one ohm and find an amp to power them, or get 2 Orion HCCA 15.2 subs and get an amp to power each.~K.Gren~

you probably need to design a better box. since your bow is ported and you have so many subs in that same box they probably interact with each other and you might be getting some cancellation. ported box setups can be really tricky especially as you start adding more and more woofers

What kind of money are you looking to spend and are you going to keep the 2nd row seating?

Lots of $$$$$... That's what you need... My dream system is in the 10's of thousands... :(do it myself inc.

you dont necessarily need to throw tons of money into a system for it to be really loud. sometimes less is more you just have to know what you are doing and do some research before you go off and start buying everything that's shinny but not really what you need.

what kind of boxes (plural???) are they in now?? If they are in crappy prefab enclosures you can get louder with a new enclosure. For the noobs to know...its about 80-90% enclosure. Not all about the subwoofer. I'm sure your current subs have much potential with a new enclosureCustom Enclosure Design
