need some sound advice to pound

DD is very good for ouput. The break in time is just as it says. Kinda like when you have a new engine. Everything is tight and needs to loosen a bit to get the most out of the subwoofer. What do you have available at local shops?

ok im going to run you some options that will help you pound harder without pounding your wallet. Digital Designs are very nice woofers (coming with a VERY big price tag for the larger models). My choices for subwoofer if you are really wanting to bust some windows and blow some ear drums would be....

1. Fi BTL 15" - $384 (2000W RMS)

2. MA Audio EHO152 - $499 (5000W RMS)

3. Audiobahn AWES15P - $299 (1300W RMS)

4. Soundstream SPLX-154 - $349 (1000W RMS)

5. Hifonics Olympus OLM2415 - $369 (2400W RMS)

A setup using any of these subs will basically shake all the bolts in your vehicle loose. If you were to go with the MA Audio EHO i would probably only say to go with two because of their massive power capabilities. As far as powering these subs goes you will definitely need more power than you have. You will also need a much better box build. You would probably be fine with going with only 2 of any of these subs but its your choice. For a box design you should visit pwkdesigns.com. The guy there is a genius at box designs and you can buy a set of blueprints custom made for your application. The kind power you will need for this system will probably require an upgrade of your car's electrical system (larger altenator and more batteries).

i would have to agree and the Fi BTL you can get fully loaded which will handle 5000rms

Hello guys. The stereo shops in my area are as follows.

Car Stereo City

Stereo King

Outragous Audio

Car Toys

Not really much to choose from. I went online to look at some of the dd's. I could never find more than 1? I have 6 cases of dynamat, 3 kinetik hc2400 battery's and 2 brand new special wound alts with another alt bracket for the second alt. I have 0 guage for all my big 3 already done. I don't know anything about what bracket I would be in if I go to a db compition? I cannot find one that is coming out my way anytime soon? I would really like to have either 6 or 4 subs. I know that for most of you that would be overkill.

I will be trearing apart the suburban in the next coming weeks and will be sure to take lots of pics for the forum. I am going to put off getting the subs and amps until everyone tells me their opinions. I appreciate everything guys. Thank you. Phillip

Why does everyone think that you get power in numbers of subs?!!!  I took my 1 dd9512 to a redline comp and smoked 4 15 alpine type r's that had 4000 watts goin to them.  If you really wanna go loud and win some comps heres my dream system..........  

2 dd9512s in a 6 cubic foot box port tuned to 40hz

and a stetsom 7kd amp which will push about 3500 watts rms to each sub.  If you do everythin right you will probably be able to hit over 160db. 

O and just to let you know the world record is currently being held by 1 sub.  1 18 inch dd sub with 4 stetsom 7kd amps goin to it hit 180.6db
