I just installed a Pioneer AVH-1400DVD, Audiopipe APSM-1500d, and Kicker L7 12 in a friend's 2011 Dodge Challenger. It all came together good. Sounded great while playing music off of his iphone and flash drive. And it sounds good when using the radio until i turn the bass knob up (max output at about 750 watts at 1 ohm). The more i turn, the more static i have. I have never heard of this happen before. What could it possibly be?

was wondering if anyone has benched these yet. was wondering how much power they put out at 4 ohms bridged. al

can a one wire self exciting alt be wired to the same batt as the stock alt ? or can two stock alts run to the same batt ? or would they have to be two seperate power systems ?

Alright I know I havent posted anything on here in a while but let me bounce and idea off of you guys... I bought a d3100 recently and upgraded my grounds and I am about 13.9v on full bore depending on my rpms. Now I am pushing a dc lvl 5 15" on a SAZ-3500D. My question is - do I buy another 3500D and put 7k watts (not sure what clamped would be) on it? Its a d2 woofer so I think its possible to wire it down to 1 ohm using 2 amps.. My other idea would be to get rid of the 15 and get 2 dc lvl 5 12s and another 3500D. In order to power both my ideas I would need another 3500D (or sell it and get one massive amp) and another 3100. Oh and I also have a 200 amp alty with the …

I have a 1.5 farad capacitor a friend gave me and I'd like to put it to some good use. I have a small mtx amp powering a pair of JL coaxial 5.25" speakers and a punch800.2 bridged for my RE HC 12". I understand some people are against using caps but I have one so I might as well use it. And generally they are used for the amp powering the sub however, in my case I highly doubt it would do anything noticable. So here's my question: What would happen if I hooked up the cap to the MTX amp that is powering the front speakers? Would that give the MTX amp a little extra boost? I believe it's a mtx roadthunder and it's pushing maybe 50rms total.

I had a guy offer me a Kinetik HC600 for $30 today. He said it was in good condition and everything, just trying to get rid of all his old equipment for his new build. Are these things any good, and is this a good price for one? I was planning on getting an extra battery for my trunk soon anyway so this may help.. what do you guys think?

I'll be powering a 12" xcon off a saz 1500d and mli65/not sure about tweeters on a sax 100.4d in a 96 volvo 850 glt. The stock alternator is a Bosch 90amp, and I'll be replacing the stock battery with a Kinetik 1400 (already purchased). I'll probably be putting a kinetik 2400 in the back as well. But will this be enough? I have 235k miles on the car, so not sure if I want to get a heavy duty alt. Also, which charger should I be using: 45, 60, or 80 amp? Posting here since it's 10pm and likely won't get an answer from kinetik soon (holidays), but I did email them anyway.

SparkFun Electronics - DSO Nano - Pocket-Sized Digital Oscilloscope seems pretty decent, not sure if it covers the ranges needed to detect clipping from HU and also to set my gains properly...Any input? Thanks.

Wow it looks like nothing came up... So, i'm wanting to get a Sundown SAE-1000D to power my Fi Q10. My sub has dual 1ohm coils. My question is, what will i have to do to keep my amp from burning up if i wire it to .5ohms? If planning big three and a bigger battery. Any ideas? Thanks, Michael

Will be installing my second RF T1500bd-cp tuesday and need to know if i should use a spliter on my rca cable or use the pass thru on one of the amps?

I currently have a kdc 138 and I was looking to upgrade and I was wondering if anyone knew would I be able to just plug in the 993x?

Well, i dont have a problem but my dad and brother do. They are trying to hook up a new HU and it wont power up i guess. He said that after it not working when wired through the wiring harness, he hooked it up to a battery to see. Still wont power on, but he only hooked up like 3 wires... 12volt accessory, 12volt battery, and illumination. He only had those 3 wires hooked up so he could just test the radio. Do you need to connect all of them to get the radio to go on??

Did you know that of all places Circuit City is now stocking Eclpise?? I have just gotten and installed the CD-3000 and I do have to say it is VERY nice for the money. Not a ton of features that you dont need but it seems to have good clean sound. Nice 5v constant outputs from the pre-amp. A few built in EQ's and a somewhat OK cross-over. It playes MP3's ect and has a pretty nice display! I would love to see the CD-7000 in action. Then again.. I dont need navagation! Good day all!

I have a simple quick question. If i wire my new kinetik 2400 in parallel to my stock car battery will i be fine with my 3000 watt amp? some people are saying i must get an isolator and others not. and i have no idea if it will damage anything or not. and no i wont be playing music without the car on

I measured my GF's CDA-7893's pre-out voltage this morning ... Here are the results. Notes: My multimeter only does AC voltage to 1 decimal point. I only did the subwoofer pre-out, which is rated @ 4 volts. I measured at the end of a 17 foot RCA cable. Battery Voltage = 14.39 volts Subwoofer Volume = +15 (0 dB) All filters off EQ flat No loudness No MX etc. Volume - Voltage 0 - 0.0 1 - 0.0 2 - 0.0 3 - 0.0 4 - 0.0 5 - 0.0 6 - 0.0 7 - 0.0 8 - 0.0 9 - 0.0 10 - 0.0 11 - 0.0 12 - 0.0 13 - 0.0 14 - 0.0 15 - 0.0 16 - 0.0 17 - 0.0 18 - 0.0 19 - 0.1 20 - 0.2 21 - 0.3 22 - 0.4 23 - 0.6 24 - 0.8 25 - 1.0 26 - 1.2 27 - 1.4 …

wat head unit i should get for and suv for Fi BTL 12 or 15" and high and mid speakers which one r good high and med speakers

I have a Soundstream RUB 1600 watt amp wire at 1 ohm. When I set my gains I used the typical 50hz, sub wires disconnected, etc... I set the voltage to 40 volts on the nuts. Hooked everything back up and let er rip. Sounds fine. Well I finally got around to mounting the amp and cleaning up the wires. Before I did that though I double checked my gains. Voltage was at 47 volts? What would cause it to rise like that? I used the same tone as before. So I have been checking it off and on for the last couple days and sure enough, volts keep rising up even the the gain knob hasn't been touched. Any idea on why it would do this? I've checked everything from the battery back and ev…

Alright, so i own a PG Ti. 500.4 and my speakers will randomly seem to cut in and out. All of a sudden only 1 speaker in my car will be working, and at other times all 4 will work. Now i went back and checked my amp, it seems that the aux inputs are the problem. When i wiggle them around a bit, unplug them and plug them back in they all work. They will work for like a week and then start cutting out again. I actually ended up taking the cover off and looking at the solder points on the amp where the inputs are and they seem to be fine. Should i just like... tape the wires in place so that they dont move? Idk what else to do.

I am looking for some real world tests done on the 3 types of batteries that show current draws to voltage drops, charge rates, how they funciton and how they differ from one another in a more technical way than "one is wet and one is dry" i seem to recall reading some where that AGM could deliever greater power in a shorter time than a standard lead acid but i cant find anything confirming or deneying this on google. thanks.

hey yall, i just wanted to get your opinions on the volt meter i have. i actually bought this Autometer voltage gauage quite a few months ago for around 60$ (msrp 120$) and um i thinking should i get that install for my system? or should i get a digital one since this one is a gauge and it doesnt tell u the EXACT voltage.. and if the digital one.. which one should i buy? no one near me seems to be selling it less then 100$... thanks!!

How do most HUs hold up under high voltage, say 16V?

I just purchased a sundown 100.4. I'm going to run 6.5's in the kicks and two 3 inch mid ranges in my front pillars. I am going to band-pass channel's 3&4 with the subsonic filter set at 150 hz then setting the Low pass frequency crossover at 4,500Hz for the 6.5. Then channels 1&2 would be set on High Pass and the High Pass Crossover set at 750Hz for my pillars. I will also be running tweeters, those will be running on channels 1&2 also, but those will have a passive crossover set at around 5khz. This is just a rough draft. Now I was wondering can I use my o scope to setup the crossover network. The dials don't have any accurate marks neither do they click.…

i dont want to second guess myself so im trying to get another opinion on a good estimation of what size fuses i need to get. what im running is a kinetik 1800 in the hood and a kinetik 1800 in the back of tundra (ext. cab with seats taking out) with 2 runs of 0g. i have a 180 amp alt under the hood complete with the big 3 all in 0g. I have two ANL inline holders, one in the wire right after the + terminal on the kinetik in the hood and then one on the wire in between the alt and + terminal on the kinetik under the hood. What size should i get for those two (they should both be the same right)? are there any other places that would be ideal to place an inline fuse. then i…

Would it be better to install a kinetik HC 1400 and replace my original battery or could i just add a smaller kinetik like the HC 600 and have my original battery and the kenetik. im on a budget and it would be a lesser dent in my pockets if i had the smaller kinetik also will my stock alternator be able to handle either one. or do i have to upgrade that too? im getting the hifonics brz1700.1d amp and i dont want any voltage drops, cause it already drops with a sony xplod amp

Who has the best deal on 1/0 wire? I'm looking to upgrade from 4 gauge to 1/0.
