Ok I have a dual brand double din trying to hookup to the pac rp5 gm31 to retain chimes steering wheel controls etc on my 08 silverado....the harness off the pac unit for SWc has the option for a 3.5mm jack and a blue wire yellow stripe..the 3.5 mm jack won't work because the dual double din doesn't have a plug for it....the dual stereo has a swg(ground) and sw1 and sw2....what needs hooked up I can't find answers anywhere on this any help would be appreciated

I’m trying to see if someone can answer this question for me in simple terms. Basically I want to know what is going to happen to my signal as it’s going to be transferred and how multiple equalizers, crossovers, and gains will affect it. So basically, my head unit has a built in equalizer and crossover (they’re not that great though.) From my head unit the signal will go to an external equalizer I have. From the equalizer the signal is going to go into a stetsom 3way 6 channel crossover. The crossover is a crossover (obviously). From the stetsom crossover the signal will go into my full range amps. I have 2 amps, one for mids and one for highs. Now to make things even …

Looking at buying one of these,but cant find any user reviews anywhere. Does anyone run hertz amps? This thing supposedly makes 2k at 2 ohm! Seems pretty badass!

I just spun myself out on this, I feel like I know the answer but fuck it If i'm running an amp that draws 400a rms, and I have a 200a alt, a g31 under the hood 4/0 to the rear bank, and 6 g31's in the rear, I fuse appropriate for the wire always, not the peak rating of my alternator yes? something like, 300a for 4/0 iirc. If I already plug up the bank and charge it fairly often (once a week), no real concern for such a small alt supporting that bank, correct?

so i went to spl show and wanted to see what my two sq hds200 dual 2ohm that is wired for a 2ohm load and even checked them with d.m.m and shows 2.1ohms but my mtx thunder 1501d older style no elite suppose to do 1500wrms@2ohms with 14.4volts has 2gauge welding wire and at the car audio show it only clamped 844watts. Im wondering why is this and is there something im missing here and how to fix this to get my wattage up because my spl score in my 00 s10 ext cab was only 142.3 on dash http://www.termpro.com/asp/officialevent.asp?EventID=15579&Method=1000 name is david downs i entered the hardcore truck so i could have door open driver side and then unlimited car truck…

I forgot to rewire the BTL to 4ohm when I swapped it with my 15's in the HT, and while I was doing so, I began to wonder, if my amp is only 4ohm stable, how does it function exactly, under 4ohm? (I had it wired at 1ohm for the Neer) For example, if you sweep the box, and you measure your entire playable range, and it never exceeds the rated RMS of the amp, say you're wired at one quarter rated minimum like me, and you have it set conservatively, and safe, does that prevent premature failure that low impedance is known for? Is that how people run amps at .25 daily and shit since it's only passing the rated amount of power through? I always assumed they did that for comp…

I read some where that all alpine head units have crossovers that cut off bass at 30hz so they want allow you to hit the low lows. Is this true or just internet BS?

Greetings Folks, I was in to mobile audio around year 2000. Back then the Big Box Brands like you found at Best Buy were OK but the high end companies had a significant boost in performance. Lower noise floors, met rated power output, better thermal management, and cleaner sound. Today I see that the mainstream companies products pricing has DROPPED dramatically. I wonder if quality has suffered as well. Let me give an example... Sounstream 15 years ago was a high end company that made top shelf products. Today they are owned my the corporate overlords and have mainstream products. This amp caught my attention for price, performance, and looks. …

Hi guys, I have recently been saved by a cheap voltmeter plugged into the cig-lighter 12v input. It showed me I was loosing voltage badly. I found something was burning under the hood. The plastic on the wire coming from the positive post on the battery to the alt was bad, and the cooper was touching a metal part. I took it off, and now everything is ok. The alternator works as usual. But now I want a better voltmeter. This one is 8 years old ! I want something small enough to fit anywhere. I won't cut anything in the dash to have it mounted, so I liked the cig lighter plug a lot. Which model do you run ? And second question : if it's…

So ive had this issue for awhile now. my headunit is Alpine CDE-164BT id say around 4 months ago, i first noticed this issue my headunit would randomly shut off for one second, then power back on. when it would turn on, its as if i just turned my car on, it displays the alpine logo and then starts to work again. the good thing is, its always turned back on right away. but the weird thing is, its extremely random? like when it has this issue, it will normally turn off around 4 or 5 times within 10 minutes. but, these random instances only happen maybe once every 2 or 3 weeks. from what ive been told and heard, it seems i would need to check several thin…

So I'm starting on my front stage. Finally got a car. It's a 98 camry. I'm trying to find a decent head unit but I'm not trying to spend 300 bucks on one. Any recommendations? I used to have a boss and Jenson but they would freeze when I turned my subs on I'm not putting any subs in the vehicle not until I got a little more money.

What are the pro's and cons of Korean built amps compared to Brazilian and Chinese. And for daily spl builds which is better.

Need some help with my alt. I have an ohio gen 300+ amp alt and it was bought for my old caravan and had a plug harness so it was able to plug into the vehicle plug . . Now I got a 93 cherokee and the alt will fit but on the jeeps stock alt instead of a plug there is 2 wires next to each other bolted to the alt rather than a 2 pin plug. . then a ground and power for the alt. . I know the 2 wires on the harness on my high output should connect to the 2 wires that are on the jeep that bolt to the stock alt but how do I find out which one connects to which?. . Let me know if that doesn't make any since and ill try to explain it better lol

Has anyone ever seen a JL audio HD1200/1 amp dyno'd. I'm just curious as to what kind of power they actually produce. Seems like every other amp in existence has been tested except the HD and slash 1200's. I'm guessing but I would think they do slightly over rated like 1250watts just curious if anyone has tested them or knows for sure.

I recently had been in the market for a DSP, and ran across this pice of equipment. The PPI DSP-88r and some input from fellow car audio nuts. Is it worth the $209 bucks. Pros. And cons. Thanks in advance

I'm curious as to what I could upgrade to with my current electrical system. I currently have zero issues with voltage at full tilt with all lights and a/c on blast, steady 14.0 with my AB PH-4000 and Lanzar Vibe 231 (ick, yes eww) I have two group 65's and a group 29 ran with zero, big three with 200a alt. Batts are under backseat, so pretty short runs in my mountaineer. I used less than 30ft of wire (direct runs both positive and negative). How can I estimate this myself for future reference?

Just curious if anyone knows of a double din touchscreen hu that could keep up with something such as the 80prs audio control wise. I like to use cds and usbdrives, so extra points for those additionally.

I feel like this question has been asked, but I did scour the web and went 30 pages into this forum looking for advice. But I still have questions! When installing a second battery, some say get the same as what's under your hood, but some say it doesn't matter. Opinions? How do you suggest securing it in a trunk? For a battery such as an xs, do I need to put it in some sort of case? If the batteries are wired in parallel, do I need to hook up my speakers and sub to the second or can I just leave them on the front and the rear battery will flow through it? These are just a few examples of questions because I am completely blind and when it comes t…

Quick question for all of you who are a lot smarter than me! My math told me it wasn't enough but I wanted to double check with you all. If my sound system drives 4100 watts will a 270 amp Max 200 idle alternator be able to support it? Especially accounting a/c etc. If it will that would be awesome, but if not I'll just go with SSA Icons instead of xcons. Ps I know I could probably get multiple alternators but it would be a tight fit, and personally don't have the capability so it would probably cost too much.

Hello! I really am looking forward to upgrading my car audio but have run into "crossroads". I would love to go the raw driver option, but I do not know or think I'm inclined enough to get an active crossover.. in your opinions, is it difficult? Or does it just take a lot of patience..I only ask because I have my eye on a Focal K2 Power 130 which would have it's passive crossover. Also have my eyes on jbl 670 GTIS component set.

So I was just curious when wiring a voltmeter to my amp, can I just put the power, remote, and negative wire directly into the amp where the battery wires are put in? Or do I have to try and splice them into a "Y" right before they enter the amp?

Hey guys quick easy question, my vehicle is set for a 24f battery, and I was look at xs batteries but they do not have one and said to just use their size 34. However it is slightly smaller so does anyone have any recommendations for a 24f sized battery? Or should I just go with a 34 xs?

I currently drive a 2013 Dodge Avenger R/T with the 3.6liter V6 and I have 2 JL 13w7's, 2 HD1200/1's, Alpine 137bt HU, with Alpine 200watt power pack running JL C2 61/2's in front and C2 6x9's in rear and stock 31/2's in my dash and I also have a audio 1000 watt capable battery in my trunk wired in with the factory batt. As of right now I'm only running 1 sub and 1 amp and I wandering what kind of electrical upgrades I would need to run both sets for 2600watts that's 2 amps and the power pack together. I'm gonna do the big 3 and add another 1000 watt capable battery, do you guys think this would be enough, or would I need a high output alternator as well. I pretty sure …

What is the problem with linking amps? I always hear its not good to do on here. I have my 2500s linked right now and wanna know what the problem people have with that is. If it would be better I would get some rca splitters and just run one to each sub

I was swapping my pioneer hu out and putting my sony back in, and somewhere during the installation something happened, and now my T250x4 doesn't turn on anymore. The board stinks like a dead amp, but the internal fuse is fine, and the inline fuse is fine =[ I am not sure where to go from here as far as fixing it, everything else in the car works fine, and I'm just weirded out that it might happen to another amp. Thinking about replacing it with a PPI900.4 o.O I checked all my wires, even pulled them out, inspected them and re ran them (I only have 6 or so ft of 1/0 power, and a matching ground run to a block, then from the block to the amps). I sorta feel retarded. M…
