Well i won yesterday with a 148.5... i now have 2 15" mts and 2 MM4000.1s. so i gained .5 db by adding 8kw and another 15 lol im so ashamed... but i still won. my electricle system is the main problem with only 1 750cca battery it need serious help. (car cannot run in dbdrag). so what im gonna do is change to street c so i can put a battery in the back of my truck, and a battery under the hood.

unfortunatly i have some issues. i can only build up about 14 inchs from the floor of my truck. street c has to have the box below the windows in the car. either way im horrifyed by that score considering i did a 148 with one of each legal and a 151 in my driveway. but i did make my gf really sick with eminems go to sleep! she almost puked! i forgot how loud 148 is!

cool...........keep kickin ass

well its not that kewl i wish that score was like a 153-155 and it should be i just dont have the damn room in my truck to get the airspace those mts crave...

Hey Bill, a win is a win. I am sure you will figure it out. I was just outside tuning my system, the center channel still isn't done so I can't take it to a contest yet. But it will get there. I am planning on going to a show just about 100mi south of me that is a USAC 3x competition. I hope to do very well then.

just got word they are going to do some usac comps out here!

Cant you add the batteries below the rear seat?

Just a thought...

Also I think theres a company called GMB or something like that. They make 8 Volt Batteries so you can get your voltage to 16V for comps

Trouble is you need them charged before you get there and its only good for a bit like all batteries...

if you want to keep with one battery, switch the starter battery to a Kinetik 2400 before the event.

as for adding a second RE MT15, and 8Kw of power and only gaining half a dB, that sounds like you may hve an issue with cancellation or something.. if this is in a truck, you may also have a pressurization issue, which could be overcome by finding a place to vent (say, through the firewall behind the dash) the cabin to outside air without having to roll down any windows.

Otherwise, look at a battery isolator, and adding the Kinetik in back, as a dedicated audio battery if you do change classes.

well this main issue is no room under the hood. i have no room for anything bigger than what i have in there now. ryan 16v is now illegal in most sanctioning bodies in my classes. although some people stretch the rules and run 20+ volts. im probably gonna throw either an nsb90 or a kinetic 2400 monster in the back. i didnt gain match the amps i didnt have time but what is the best way to do that?

best way?
with an oscilloscope.
you need to measure the output on the scope and match them so each is putting out the same power at the same volume position.

guess i need to buy an ocilliscope any other ways to do it?
