  10. Good voltage too good to be true?

    and the 3k is both amps combined (my bxi2607 and p400.4) But then again my 400.4 isn about 60% gain on front and rear channels and but the 2607 is gained out max without clipping no bass boost of course

    gain position doesn't matter. how the fuck do you have the gain maxed out on the hifonics? only way i can see that is if your headunit preouts output .2v

    I shouldn't of phrased it like that I didn't mean I had it maxed out as in the knob cranked all the way, I tuned the amp with an oscope and its as high as it'll go without clipping I mean...

    i think your ok... if i was you, id just maybe add more reserve (bats) and spend your coin else where until you see some dip....

    your meter is fine... even if it was a cheap turd.. and it wasnt totally acurate, your also looking for drop... if your meter was off, you would still see drop.......... and you see none...(or not anything ape shit)... so, start thinkin a bit bigger!!!...just my .02 coins

    Sounds good I think I will grab two batts and take out the stock batt...

    If they are both reading the same I'd say you are golden, the odds of 2 diff. meters giving an identical, and off, reading has got to be almost impossible.

    hmm well now I'm wondering how the hell my stock electrical is stabily keeping almost 3k of wattage going...

    impedance rise probably

    x2 probably not seeing the full 3k

    I got em wired to 1 ohm...I touched the leads of the dmm together and they present 8 ohms of resistance and then I measured the speaker leads and they were 1.8...

    Sooo I got a voltmeter in the mail yesterday and threw it in the car hooked up to my sub amp....driving voltage stayed in low 14s high 13's...resting voltage with the acc on was about 12.3.....Then I tested it and let the subs rip full tilt on some decaf and the voltage stayed in the mid to low 13's and high 12's. So I took my multimeter and put it to the sub amp to double check and make sure the voltmeter wasn't trickin me..it read the same exact thing!...Is it true that my voltage could stay that good? I only have the stock battery and stock 160 amp alt right now with the big three and I'm running a bxi2607d and a p400.4 off of that..

    Also I did mount a 1.5 amp bat charger in the trunk and I've been pluggin it in for the last 2 nights since I got the charger...

    I've had the same problem with my pioneer headunit.

    Every thing you tried, I have tried as well. but still failed to fix the noise.

    Until I used an inline power noise filter.

    I just matched up the fuse rating to the headunit and bought the one closest to the fusing.

    I used this one

    But here is a cheaper one But does the same exact thing, but looks better.

    *Edit* lol nvm im slow...this goes like you connect the red to the constant 12v and then ground the black and then connect the blue to the battery constant on the h/u correct?

    Does the hiss go away when you unplug the rca's from the amp? Does it go away with them plugged into the amp but not the head unit?

    II don't remember exactly I know I tried that though but say if I unplug the rca from the headunit and keep the rcas plugged into the amp can the speakers still produce ground noise?

    I ran my RCA's right next to my 1/0 power wire right down the middle of the car with the wire and rca's taped to each other all the way down with no noise what so ever.

    First pull all rca's out from the h/u and amp and let them lay there and have the amp powered and car running to see if it is your amp making the noise and connect everything back up 1 piece at a time till you encounter the noise, it is possible a ground issue it is also possible a colder solder joint inside the h/u or amp but you'll need more equipment to replace what is in there now to make certain.

    You could try and ground the rca's as well as moving the ground locations at the amp and h/u if your unable to locate it through doing the other things.

    Yea I guess I'll have to work my way from amp to headunit, although I've basically already done it I am almost positive its because of the rcas but to me it seems that if grounding the h/u rca leads didn't work that things would point more to the rca's just being bad..even though theyre brand new..but cheap lol

    the way i fixed mine was take the radio apart, and try to plug it all back in, and the whine could also be bc ur kenwood is cheap... i have a poineer avh3200 double din and have had no whine what so ever

    saying I have whine because I don't have the same h/u as you doesn't help at all...thanks tho

    why are you using splitters and such? do you only have two preouts?

    Yea I only have a front preout and then one rear/sub preout

    I have a ground loop and it's driving me freaking crazy...my system consists of a kenwood kvt-512 to a rf p4004.4 and hifonics bxi2607d...I have the front preouts to two splitters into the 400.4 and the rear preout is goin to the bxi2607d...The rear preout used to have a ground loop too but I fixed it by grounding the rcas to the headunit...The front preouts though are driving me crazy It hisses when the car is in acc position and makes a high pitch tone AND hiss when the car is on all the way. It used to be much worse the other day but I put a ground loop isolator on the front rcas and it helped quite a bit but I still hear it Heres all the things I've tried all ready

    1. grounding front preout rcas to chassis ---fail

    2. grounding front preout rcas to h/u ---fail

    3. grounding 400.4 to chassis rather than the battery --- fail

    4. grounding h/u to different ground on chassis --- fail

    My front and rear rcas are ran through the center of the car and are not ran with ANY power wires at all...what should I try next?
