*UPDATE* Well big 3 done (was 4ga, now 1/0), 150 amp alt installed, xs power D925 installed in trunk, head unit changed out from 2v pre to 4v jvc KD-X340BTS, and amp (Orion xtr extreme 2500.1dz will arrive tomorrow. Stay tuned........

Do you changed everything except stuff thatbeffects the woofer?

Big three and alt effect amplifier

Xs925 is a tiny battery that’s prolly won’t help much. Shoulda bought a Duracell AGM g31

HU rca voltage doesn’t matter, that’s just means u gotta adjust the gain on your amp.

The Orion 2500.1 should be nice power for the xv2 though.

Not really. It’s not going to be magic. It’s a install issue. Amp will help a bit but it’s only a few db gain. It will wear off I a few weeks.

head unit voltage does matter when the original head unit cant put out a voltage high enough for the amp to reach proper gain settings without overly distorting. As in those head units that claim 2 volt pre-out but is not even 1 volt. Overall quality of the starting signal is important too aka better DACs, Amplify a weak distorted signal, you are gonna get distorted bass the clips prematurely. This is why stock head units and line out convertors are always a few db behind a real head unit with a real sub out, every swap i've seen done has always netted spl gains.

So are you telling me there won't be much gain adding 1,000 or more watts to a sub???? And what is installed wrong?? Installing is not rocket science, maybe all the eq settings but definitely not the install..... I need answers???

Get an app on your phone to play sine waves and just let the sub play a sine wave at a very moderate volume so it can break in faster. an also that way you can figure out what the actual box tuning is.

WHen I first built my box and fired up my sundown e12, there was almost no bass but I just let it play a sine wave for 20 hours and then turned up the gain on my pg xenon 400.1 and this little farter started going like it's supposed to //content.invisioncic.com/y282845/emoticons/santa.gif.e1ec9cf2e0a0dd232ad35aa594a126d0.gif Sundowns are known for their raw bass and can take a good beating.

if it doesn't start playing, then it's either the box or the signal.

the amp will help yes..

 

[shredder2]

Once you get a good signal to a strong amp that'll move that X... you might be happy... you're doing all the things that needed to be done anyways now... it'll be done right now... electrical... amp... strong signal... with a weak signal on a HiFonics there was NO telling how much actual power you were getting

I don’t think his HU RCA voltage is going to fix his problem.

Somebody getting frustrated lol

Yes...install isn't as easy as putting cheese on a hamburger. It takes thinking involved.

Watched an old vid of yours from 2016....oldbass40 took the vid //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
