Question

i know this is gunna cost a lot of money...i have been researching a lot and i want to know what advise u can give...heres my situation... i have an envoy with 2 15" mtx 8500s and i want to go way louder( about 10db louder)...i went to a small comp and hit 140.1 db on a bad amp...now i want to hit 150 while still maintaining fairly good sq....IM ASKING U TO DESIGN ME A SYSTEM THAT WILL HIT 150 DB AND BE ABLE TO BE PLAYED DAILY (no soloxs or demo car stuff) AS WELL AS TAKE 1ST PLACE AT A COMP....TELL ME WHAT U WOULD DO TO GET TO 150 DB(small comps of course no 179db stuff lol)...tell me everything from woofers to batteries

THIS QUESTION NEEDS A LENGTHY ANSWER BTU I NEED UR HELP TO GET MY HEAD ON STAIGHT HAHA! THANKS!

Answer 1

Whatever make or model you get, make sure it comes with detailed instructions on lip reading and sign language because it won't take too long at 150 db for you to do permanent auditory nerve damage.

Answer 2

The thing about hitting high dB's, is that you are going to have to focus the power that each sub is delivering onto a single point.

Find out where the mic is positioned. (dash, seat, etc..).  The next step is to build a box that increases the efficiency of your subwoofers, and focus the sound on that point.  Your box needs to be tuned to specific frequency (based on the subwoofer being used), usually using the free-air frequency of the subwoofer.

If this is done correctly, the box will effectively double the amount of power being delivered by each sub, which will probably add a couple of dBs.

The downside however, is that you will be loosing the entire rear of the vehicle (these boxes arn't small), and you will have an absolutely absurd peak in your response curve.

With that being said,

2  DD 9915c 1 Ohm Quads in Ported Enclosure Tuned to 33Hz.  (Box size depends on mic position)

Pair of Rockford Fosgate T4000.1 dBs

Everything else is far too dependent on how your system is setup, and what kind of vehicle you have.

Answer 3

4 - Lanzar opti1535d 15"

1 - Lanzar opti6000d

4 - Kinetik HC2400 power cells

The enclosure will have to be designed around your vehicle there are to many varibles to give you specifics

I would call and talk to powermaster about the altenator for your envoy.

This is what I would recommend right off the top of my head, there are alot of different manufactures you can use.
