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

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.

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…

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

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. …

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?

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'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.

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

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'm looking to do the big 3 on my 98 expedition. I was looking at the wiring from alt to batt and there are 2 runs of wire. Both are fused. Either 150 or 175 amp fuses. Am I alright to run wire straight from the amp to the battery? Or should I replace wire from alt to the fuses then fuses to batt? I'd rather leave stock wiring there and then run a 4 or 0ga run straight over. Of course I'd just do the 2 grounds chassis to block, block to batt. Any have experience with a late 90s ford?

What can happen if to many things are hooked to one remote wire? . . . Every once and a while my amps will shut off like there protecting and sometimes the cd player will shut off but volts will be in the low 13s . Could this happen from alot of things hooked to one remote? . I have both sub amps. My 4 chan amp. An eq and both volt meters all from one remote

Is changing passive crossover same as changing headunit EQ? like i have a 9 band parametric EQ on my alpine 164-bt. and i have alpine spr 60c component speakers. the highs are very harsh. and im debating attempting to mess with my doors to edit the crossover. i have absolutely no clue what im doing with it. and dont want to risk much. i cannot find any videos for the year my car is. i have 2013 hyundai elantra coupe. only video i saw was for a 2005 elantra, 4 door. mine is a 2 door also and many years later. and about the passive crossover. i cant find any pictures only or guides on how to change and edit the crossover? what exactly is an EQ changing…

Installed a self exciting high output alternator worked fine once installed but once the car sits over night if the temperature drops below 30 degrees the next morning when I start the car I'm not charging, voltage is at 12.3 I have rev up to 3k still it takes probably 20 seconds or more before my voltage goes up to 15.1... on warm days and nights never an issue. .what could be causing this?

So i believe my headunit can go up to number 35 for volume. When playing music, around 12 is pretty decent loudness, but up to around 16 is pretty loud. and i dont think i would ever turn it above 20. when there is no music playing, my speakers hiss quite loud. the same volume of hiss can be heard when the headunit volume is set from 1 to around 10. any volume above 10 on the headunit, then the speakers his increases with each volume increase. i dont really notice the hiss when theres music playing. just wondering, is this normal? is it a bad sign? how might i go about fixing it?

I ordered a hifonics zeus 1800w amp. The spec sheet online says it uses 4ga inputs. I feel like 4ga is rather small for an 1800w amp. I know I can get wire reducers, but could I just run 2 fuse holders, and on the rear at the amp go down from 0ga to 4ga? Or should I just run 1 fuse, and solid 1/0 run to a reducer?

Pioneer GM-D8604 http://www.sonicelectronix.com/item_63974_Pioneer-GM-D8604.html its $140. class d RMS Power @ 4 ohms 100 watts x 4 channels its around $100 cheaper than the next comparable amplifier that has RMS listed and is a decent name brand? Im aware that its class D so, thats part of why its cheaper. But other than that, im worried its bad for some reason because of how cheap it is?

Im getting Alpine Type‑R SPR‑60C 2‑way Speakers. rated at 4 ohms Going to be using an amplifier that can output at least 100 RMS each channel. up to around 125 RMS per channel. My car is a 2013 hyundai elantra coupe. I tried asking dealership if they knew the gauge of the factory speaker wire. or how to figure it out, in some manual or booklet. they said theres really no way to know, unless u measure or look at the wire itself. I tried looked at youtube videos or other sources online and couldnt find anything specifying the gauge of the factory speaker wire. Im assuming its between 18-22 gauge wire? I heard that something such as 20 gauge wir…
