Hey guys, first off I'd like to say great forum!! I have learned so much here and acquired so much inspiration from reading others post that I took on the challenge of trying to unsuck my Ram factory Alpine system. I'm hoping to find someone here that has some experience with this truck to help me in my quest. I'm deep into trying to make this "upgraded" Alpine system sound good. I wont bore you with what I've tried because that list is of great length.. I'll just start with what I have now and where I'd like to go, if that is okay.
Hertz 3.5 in the dash (all 3), Hertz 6x9 3 way front and rear doors and Hertz 1" tweeters in the front door panels to add a little extra touch (the front doors are crossed over at midbass only.. should have went with a mid driver was unaware of crossover points at time of purchase). Two sundown SA 10s on a SCV 2000D in a Fox acoustics box, Fosgate 1/0 amp kit, LC2I LOC, 220 amp alt, dual batteries.
The doors and dash speakers are running off the factory amp and crossover points. It sounds amazing compared to the Alpine factory crap that was in there.. The LC2I is hooked into the factory sub channels
The subs is where I keep having issues, I am not sure what frequency the factory sub channel operates and can not find any information. I'm assuming its low as I have unloaded a sub or two to the point of mechanical failure thinking the factory sub was protected by some kind of factory crossover point.. The Box is 1.35cf of airspace per side tuned to 35hz the subs displacement is .1 and calls for 1.0 to 1.25 of air space and sundown recommends 35hz port, so this box is built for the subs. The amp is more than enough to push these things so what is going on??? Seems like the bass rolls off on the SSF way to fast low pass is set to 95ish.. I need to get this thing meter set to make sure my crossovers are set correctly but having a hard time finding a competent shop here in the 4th largest city in America.. Oh and I have the SA D4s wired to 1ohm. The SCV remote comes with a clipping light and seems very accurate. I set the gain using a multimeter using the watts x ohms square roots system, calculated for box rise so 750 x 2 = 1500 x 2 = 3000 square root = 54.77 volts. I then pay close attention to the clipping light.
1st question, since these subs are beast mode can i just leave the SSF set at 10?
2nd question, should I set the low pass higher to something around 110 to 120?
3rd question, how can I figure out the frequency coming to the amp?
I have tried the LC7I to sum all channels but it seems like it wont get low at all using this method.
I got two dc level 4 15s im throwing in the back of my accent hatchback, as you can see all amps are wired up and ready to go, just gotta build box, but I cant figure out what would be best..
its going to be a big and tall slot port box, if port is to the rear it will only have like 4 or 5 inches clearance from hatch, i noticed walled off setups are always port and subs forward and sound great but also hear to always point it backwards... with my setup, what do you think would be best? after i build it, its gonna be hard to turn around and experiment so kinda have to do it on first try.
(Sorry if bad english)
I currently have a Hifonics BRX2416.1D (which delivers 1600w at 2 ohms) for my Sundown X12 V.2 (1500W, dual coil).
The sub is 4ohm and wired at 2ohm, so it takes about 1600W.
I want to buy another X12 V.2 D4, and a BRX3016.1d (which delivers 2000w at 2 ohms) to have a good amount of power and to wire the two amps as slave / master.
But I really don't know :
- Is it possible to wire two different amps as slave master? (like the 2416.1d and 3016.1d)
- What will be the impedence if I put my two subs in parallel or series?
- How many watts will each subs recieve?
- If I manage to get about 2000w for each sub, will they take it or will they break? (I heard that sundown subs are underrated by the manufacturer)
