Amplifiers / Head Units / Processors / Electrical

I couldn't decide for the longest time and now i've finally decided. And i'm going with AVIC-D3. I bought it today now its just a matter of time until i get it in. Hopefully tomorrow. I was bored so figured i'd post. Feel free to tell me what u think about it.

i have a 2nd post similar to this but not as on point so ive made this one to nail down some questions and make things more searchable in the future. coworker was setting gains on an amp the other day and what he was doing got me thinking. if you follow mecp and set gain off a 40hz tone wouldn't the power output of that amp change drastically if the box were tuned to say 29hz or 55hz (something 1/2 or more octave above/below the frequency you are generating? or transversely if the box were tuned at 40hz...) the thermal handling of both amp and sub (assuming that's one thing you do such a procedure to keep in check) would change drastically while playing music. so wou…

I'm thinking about buying an O Scope on a budget,was wondering what you guys thought about this http://www.amazon.com/gp/aw/d/B00BB4ETJW/ref=aw_d_dsc_industrial?qid=1388172095&sr=1-4 or might recommend.It'll be a month or 2. Before I buy one.thx

Does anyone in lower/central Michigan have an O-Scope?? I would really like to use one on my setup! I live in the Marshall/Albion/Jackson Area and would be willing to drive 100 mi. or so to use one!

was thinking about getting one in a little while. I dont want to spend too much, but want something reliable. how long would it take to get familiar with one? any suggestions?

So I've tried both my HU and Ipod for a source to my amp and wired the amp to 2 different subs at different impedances. Always turns out the same way, some rattling sound coming from the speaker. So Obviously it's the amp because I've tried two of everything else. The "sound" plays with the signal, not with engine RPM, so I know it's not related to my ground. You can hear it at low volume with gain turned up just enough for sound to come out. I think it's also causing my amp to go into protect mode prematurely for some reason because it would go into protect around 30 volts on the DMM when setting with a test tone. Amp is a Hifonics 1505d (explains a lot, I know) left ove…

hey whats up im looking for a huge battery for my secondary battery something that can handle burps really well and a lil music here and there what are the differences between these two and which ones better thanks

i am considering purchasing a pc2150 from a forum member. is it possible to put this battery under the hood or is it exclusively a second battery? i am running a zx2500.1 and a 200 amp alt. i need a new stock battery and i need a car audio battery. was hoping i could solve both problems with this one battery.

With a pretty significant build on the horizon now steering towards higher end equipment, i still am not ready to part with my factory head unit unless it becomes an absolute must. I prefer the OE look and like the fact that my navi and bluetooth are integrated in the setup now, although i know that with a little tweaking i could likely make them work with something different, if needs be. On the G35 w/ the Bose system, all the processing is done at the actual factory amp. The leads running from the factory receiver are low level already and many people prefer the results with the RCA cables spliced/soldered into those leads over using an LOC. I myself initially had used…

My lights don't dim or anything, maybe slightly if i crank it up. but its an 05 Civic, stock alt and battery...is there still any concerns i should be aware of? my amps: JLA 400/4 (using 75x2 currently) class a/b MTX 1501d (using about 1400 watts, 1.33ohm load) class d 4 guage power. Overall, system seems fine, nothing cutting out..etc. The OEM alt is a Mitsubishi, no idea how many amps it pushes but i'd be suprised if its over 100a. if lights don't dim, is it ok?

Got a new build in works on Acura TL. Need amp recomendations for pure SQ app using very high end drivers(listed in my subwoofer thread). Rms over 1000 needed other than that just looking to upgrade my current bsheeted 1650 at 14.4 with >92 s/n ration, 83 db chan sep, and <.05%thd from 20-85ish. Also have to use an OEM integration because Acura thinks there stereo is perfect the way it is... Looking at JL's, the RF 360.2(or other versions) and a couple from audio control(all good shit). Basically looking for anybody who has installed or heard systems with these or other high quality amps and OEM int units. I think my choices would suffice but always considering bett…

I'm thinking about going all out in my car. I'm already building a new box or two for my Fi BL15. I'm thinking 8"s in the front doors maybe some HLCD. Rear fill will more than likely be something modest. Now here is the kicker, I want to keep the factory radio. The car is a 2005 Chrysler 300c with the Boston Acoustics 8ch system. I was looking at the JL Clean Sweep, Rockford Fosgate 3Sixty, and I recently came across the JBL MS-8. The JBL website it awesome compared to the other two, but it appears the JBL is geared more for the person not wanting to add amps or aftermarket speakers. Has anyone used any of these products or something similar? There are no real sh…

MTX re-Q, Fosgate's 3.sixty, JL's Cleansweep...there's a metric crap-ton of these Factory stereo processing units out there. Anybody got any experience with any of them? Are they even worth it?

got a new truck coming and I think I will build something big in it. (big to me anyways) 2013 Ram Longhorn I will be keeping the stock HU so I need OEM integration. 3 way components up front rear door speakers 1 12inch sub I think I will be using ZED amps (leviathan,draconia,and minotaur) I need a processor to run all this...I don't care which one, I don't care if I use the processor Xover or the amps Xover.......but I would like TA. thanks

Well I recently (2 weeks ago) purchased a Brand New Volkswagen GTI and it just turned 1000miles so it's time to play (I told myself that I'd at least drive it for 1k miles before tearing it apart.) Anyhow, I'm looking into processors, line level converters, ect.. I'd like to keep the factory deck, It's a in dash 6 disc with aux in and Sirius so I'd like to keep it for now (I've never ran a stock so this will be a new adventure) What I'm looking to do is just get some better sound.. I'll probably throw a five channel amp in there with a single 10 and leave the stock mids intact for now . Currently the stock setup sounds terrible... I've never heard a factory set sound so …

What's the difference between the wire? I need amp wire and wire for my big 3 .. I will be using knuconceptz and a Rockford fosgate punch 1000 watt

Have an opportunity to purchase a 250A Ohio Gen alt to temporarily bandage my voltage. Has anyone ever used their alts? I heard they put out straight poop @ idle so that is why I am worried. My car idles at a very low RPM: 2004 Pontiac Grand Prix

Looks like i may have found a alt for my car finally, talked to Ohio gen and they seem to be able to make a monster little alt for my car 200 at idle 300+ with some throttle. My question is are these guys still building quality products and how is their cs, would love to hear about some experience with Ohio. Thanks.

How do ohms have an impact on the electrical system.? I know that if the woofer is wired to a lower ohm rating then there is less resistance. Does this mean that a 600 watt amp at 2 ohms is the same electrical strain as 1200 watt at 1 ohm? And. I have heard that a higher ohm rating results in "tighter" bass. I believe it is a myth but I want to ask the input of the users on this forum.

Ok, so basically a gain is this : the voltage from the RCA wires is say 250mV, and the amp takes that and does its thing which would amplify it by say 90dB, which means the subs would be receiving 250mV * 90dB, whatever that is.. and then introducing the gain just increases the voltage from the RCA to the amp so the amp would perceive the RCA to be sending a higher voltage, say 250mV * 10dB of gain, which the amp would then amplify the 250mV * 10dBof gain * 90dB which would then hit the speakers.. Is that correct? All the numbers are just random, just tryin to see if I got the idea..

Im installing 4 super tweets(8-ohm each), 10 cadence mid-high 6.5 (8-ohm each), 4 kicker 8" comps for mid-bass (8-ohm each), and a cadence 5 channel amp. (tweets wont be amp'd) I have no crossover or processors yet. My question to you guys is, how would I make this work? And what do you guys suggest I buy as far as crossovers and processing?

I'm just curious without the ac converterr, what would happen if I cut the power wire and connected it to the battery, or a 12 volt connection. Would it A. burn up the ps2 B. Not get ebough power C. work just fine. I say B

Ok I was told the Sundown 4500D is a bad amp because the 86% eff @ 4ohms at 100Hz, so I was told to look into the HellFire 2500.1, the MTX TA92001, and the T1500-1bd. I am going to be getting 2 12" BTLs, fully loaded daily drivers. Anyone have any words of wisdom?

I have a 220A H/o alt for a 01 lincoln LS and I am current running just a stock battery. If I get two other batteries, even though Ive not got my amp yet, and install the alt in my car would there be any damage? Or if I hooked it up now to a stock battery would there be any damage? and second question, I flubbed up and read the ebay post wrong and ordered 2 S3400 from XS power, I wanted D3400s, whats the difference and would I regret using the S over the D series?

as some of you know, i have an 84 300D benz, and i have had this freakin 200a alt lyin around in my room waiting to be installed for 4 months. My dad is weary about installing this into my car because he is scared that if the regulator goes out, it will overcharge and blow my battery up. Other concerns are the stock wiring (not the big 3 wiring) the dimmer wire, startup wire and all that good stuff (all in a wiring harness) is going to catch fire. His wearyness has caught on to me and i am scared that my car is gonna catch fire. FYI: my dads been a benz tech for over 20 years, and worked on diesels like mine for a long time, so i kinda tend to believe him. but upgrading…
