What headunit do you have?

Excited to see this build! Tuned !

Well its weird that the new ones just flat out dont work.......are you sure you have the rcas in your rear preout of your h/u and on the input not the output of the amp?

hook up the old ones and then see if they work again...

break in? let em rip!

There's a gain and a bass boost knob like all amps....I haven't touched my bb knob... he means the remote knob that plugs into the amp with a telephone cord Oh I don't even have one I use lc-1s for both my mids and highs amp rcas and sub amp rcas..

you could also try throwin a relay in there and seein if that helps.

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...

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

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 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

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

Yep thats exactly what I did and it was right on point with my multimeter

This one I adjusted it and it was exactly on point with my multimeter 07 Dodge Charger and yep I'm almost positive mines a 160 amp one

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 actually have a filter like that already on the rcas...it helped a great bit...but not all the way > : (

*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?

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? 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

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

*Edit* I dont even remember writing this lmao but I take it back cuz I love ebay

are these good? also is the aspect ratio the same as the "series"?

hmm I looked on tirerack.com and they said they didn't have that size?
