O.k. I will be hooking up my amp (soundstream 2000w monoblock) to my factory h/u via a PAC audio plug-n-play (c2a-chy) harness. The rca voltage isn't fixed and will be adjusted as the radio vol. is increased up to 5 volts. My question is, in order to set the gains on my amp, do I just set by ear with a test tone or get a line driver and have that fixed voltage to set my gain with a dmm. My amp has a range of 300mV-5V max. Thanks guys !

I'm currently in the process of redoing my sound stage. I'm going to replace my Alpine, the front Kickers with either Focal or Rainbow components (rear fill will stay Kicker 6x9s), and most likely 2 Mach 5 15's on a Sundown SAE-1000D. I figured an in-dash T.V. head unit would help pull the chicks , not to mention I could put my XBox in my car http://www.bestbuy.com/site/olspage.jsp?sk...d=1168044601606 It seems like a good in-dash video head unit, and the store near me has it for $400, hence why I'm thinking of getting it. Does anybody have any experience with these?

does anyone have any experience with this unit ? ... can it do damage to anything in my car as it regulates the charge of your alternator to around 15.2 volts ... how easy of an install is it?

So i have an Fi Car Audio SSD 12 inch Subwoofer and a planet audio amp and the box is a groundshaker sqpxl 1 12 at 33 -35hz and how do you guys think i should tune my amp to this setup

I'm new to car audio and i need help to figure out what wires and/or wiring kits would be a good purchase for me. My system: 2 Fi Q12's fully loaded (subs) Fi: 2 Alpine SPR-13s (speakers/ 4 total) Alpine Electronics of America, Inc. 1 Audioque 2200D (amp for subs) Audioque: Amps: AQ2200D 1 Alpine PDX-4. 100 (amp for speakers) Alpine Electronics of America, Inc. 1 Alpine CDA-105 ( head unit) Alpine Electronics of America, Inc. I was looking to get wiring stuff off of knukonceptz.com but give me other websites please, and help me find all the wire i'm going to need. thank you

I am looking to buy a head unit with a built in gps. I want a high end head unit and I am willing to spend around 500-1000. So any suggestions will be appreciated. It will be for a pontiac g6 gxp.

Question for yall: I just got my saz-1500d, hooked it up, all is good. With my previous amp, I use a kicker kx3 xover for the linedriver/bass knob features on it. Just for kicks, I hooked up the kicker bass knob to the sundown amp. It works fine, but when I turn the knob up over halfway, rather than increase gain, it decreases gain. It does get to the same volume level that the sundown knob gets to, I'm just wondering if it will hurt anything to use the kicker as it is already cut into my dash. Thanks for replies.

I have a Cadence ZRS-C65 with two SA-10 D2s. When setting the gain, do I go by the impedance the subs are wired to (2ohm), or what they actually measure at when I test the wires with a DMM (2.7ohm)? Also, when voltage drops does the power drop, or does the amp draw more to keep power where it should be? My electrical isnt up to par at the moment (all stock), so I sit 13.8v idle, and drop to high 12s when the amp reads ~30v. So if thats 450w at 2ohm, which would be 32amps if it stayed at 13.8v. Since it doesnt, and drops to about 12.8v, does that mean it draws 35amps instead to make the 450w, or does it continue to draw 32amps and only put out 410w? And when figuring effi…

http://www.parts-express.com/pe/showdetl.cfm?Partnumber=265-081 Could that amplifier reliably produce at least 30w rms per channel run as a sub amp? rated for a 4ohm minimum, but with plenty of reserve i'll be running it at 2ohms.

ok im currently running sum cheap o wiring and id like to know what is the best route to upgrade it im running a 130 amp alt upped from a 60 amp. Big 3 is done with some good 4ga scraps i rounded up at the shop with copper ring terminals crimped on. I am running a RE audio dts 1500.1 amp battery is unfortunately stock till i go pick up my yellow top this sunday. Should i just get a quality O.F.C. amp wiring kit? Should I just order some welding lead and build my own? If I do either of these do i need to get 4ga or thicker like 2 or 0ga? There is also a 200 or so watt 2 chanel amp running 2 memphis 6x9s. this amp is already ran and hooked up tho so i could…

hey guys i am going to be buying an SI d2 in a few weeks and i need a more powerful amp and i only have about 250 i found a hifonics brutus 1500 watt amp on ebay for 225 buy now is it worth it or should i get a rocksford fosgate power 1001bd for 250 thanks

Have a few questions bout charging batts on an actual battery charger. I have a D3100 and a D5100 in the car. Let's say i purchase a Schumacher AGM charger. Since the rear batts have always been connected in parallel their whole time, is it ok if i charge them paralleled together? I don't really see how 1 batt could charge better than the other but i dont know for sure. Second, since i have a solenoid which isolates my rear batts from the rest of the car, is it ok if i charge the rear batts with everything still connected including all the ground cables ran to my chassis? I know not to charge while car running, that's obvious, just check the two things above.

Hey everyone. Was thinking of picking up a Crescendo Audio BC2000D amp to run 1 15" sub. My question is what kind and how many batteries do you think i would need? I have a 200 amp alt. and have done the big 3. The car this is going into is not a daily driver. Mostly just to car shows. Any help would be great. Thanks

Hey guys, so i'm at a stump with my electrical in my car. I have two sundown SA-15's in my Honda CRV being powered by a hifonics HFI 1500d. I would love to upgrade my amplifier and get about 2500 watts to the subs but my voltage is too low for that type of power. I have been searching for a compatible high output alternator with the CRV for a while now, but have had no luck. Also the alternator is located under the engine so I would have to pay a shop to go in there and install it. All lots of money i don't have to spend. Are there any other ways i can give my electrical system a boost to maintain that 13.8+ to power a higher wattage amplifier? I have already done the big…

Hey guys Im looking for a single din flip out for my car. Reason why I am choosing a flip out is because I have limited space, and still want my A/C. I could put in a double din below it but I dont want to do that. I am looking for a NAVI/GPS h/u with basic features, cd/dvd. I don't want to spend a fortune on it. My price limit is about $700. So far after some research, I am looking at a Pionner AVIC-n4 or n5. Anyone have any input on whats a good h/u? Brands? Thanks!

is anyone on here using them? I was looking through their website and found a diagram that shows pretty much exactly what I will be running so I figured I would just copy what they suggest. here's a picture of the diagram can someone fill me in on the pros/cons to running something like that? I know 1 pro would be a much greater tuning capability but not sure on the cons any input/advice is helpful edit: heres a link for the 6xs http://www.audiocontrol.com/t34/5251/18487/Car-Audio-Electronic-Crossovers/6XS-6-Channel-Electronic-Crossover.html and the link for the crossover http://www.audiocontrol.com/t34/5250/14149/In--Dash-Car-Audio-Processors/Three1-In--Dash-Car-Audio-E…

hi, i am thinking about getting a jl audio xd600/6 and going 2 way active using my 9887 for the processing. and i plan on using channels 1 and 2 for the tweeters. and 3 and 4 bridged for 1 midbass and channels 5 and 6 for the other midbass. now i am wondering by doing that. will i lose some features such as time alignment? or should it be ok as long as i have the rca's matched up right, thank you. and also i plan on doing the 2 way active this way with that amp because it is going in a truck so space is limited and this is only option that i can think of that can give me the power i want and still keep me within budget. thank you.

ok want to install my amp but i'm not sure where to put the phase at. i have a SAZ-2000D should i just leave it at 0? or where's a good place to put it? i should know what it is. BUT I DON'T :/ maybe i'm missing something here lol thanks!

Before I start going through the troubleshooting list since there is noise with the radio turned off I was thinking there might be a quicker answer. Here goes, my brother had his system installed a couple of years ago in his VW "something" I think jetta but it worked fine the whole time but a week ago all of a sudden there was noise with the radio turned on or off using the turn signal, winsheild wipers, rpm, pretty much anything electrical coming through the speakers with radio on or off like Lelu please help

well, I just replaced the alpine 7949 I bought I now have sony cdx-c90 coming... don't think I can do much better than this

I am tryin to figure out if i should install an isolator in my setup and have been reading a LOT of info about this and have came across a LOT of things that i have never read about before from others. I've read things like- Not using an isolator can hurt the starter by it receiving a superior CA load and may kill it quicker. Showing off with car off will kill starting battery. Now, i've been on Stinger's site and i gotta call them about some things because they got some products and descriptions that are just begging for answers! Such as their SRVG which shuts off power altogether in the rear to prevent front battery from dying.... really? How? And also, their 200A rela…

Hello there, my name is Mark. I Would like some input on best options for continuing to improve my electrical system. I am not satisfied with the way things are performing now. Seems like my voltage is very inconsistent and that there is way too much draw at higher volumes. No I have not hooked a volt meter up to see what the voltage has been. However, the dimming of interior and exterior lights have been a good indication something more is needed. Here is a list of what's already completed. Thanks in advance for all input and help.
