im not too sure what bass boost is or how to properly set it. some of the people i know say i shouldnt use while others say it helps...please help i know probably a noob question.

Hello, I have two 12" SSA GCON dual 4ohm vc subwoofers in a sealed box I made. (750w rms each) I was previously driving each subwoofer with an Infinity Kappa One amp, 800W @ 2ohm, but my stupid pre-out adapter decided to push 12V to the amps, frying their input circuitry. So I guess I need a new amp or two, and was wondering recommendations, and what info you need in order to give good advice. Car: 2011 Dodge Charger Hemi Sound deadened trunk (2-3 layers ballistics damper) Wire: 1/0 KnuConcepts to the amp, 10 gauge to the speakers Speakers: Two 12" SSA GCON dual 4ohm voice coils, 750W power handling, RMS Enclosure: wedge shaped, dual 12", 1.5^3 foo…

I want to know in very good detail, on what the advantage is in the difference from a 3v pre--out to a 5v pre-out?? i'm just curious.

So I get to the alt shop and talk to the guy. We test my alt with a clamp meter and a volt meter. Here is the results. No accesories 12.7@600rpm 13.9@700rpm 14.5@900+rpm Acc on (no stereo, just lights and A/C) 11.8@600rpm 13.6@700rpm 14.5@900+rpm Now here is the part that gets me. The alt shop told me that I do not need a smaller pully. Shop: "You need another battery and an isolator." Me: Why??? Shop: You have plenty of amps but low voltage. Me: OK, another battery run by itself is going to help? Shop: Sure it will... Me: please explain this to me? Shop: the second battery will no longer be tied to any of the other accories in your truck. Me: thats fine and all, b…

is it bad to run your amps during the winter

Hello, I have a 2000 Crown Vic Police Interceptor. It has a heavy duty battery and a HO 130 amp alternator. At the moment I have 2 Kenwood 12's (Yes, I know they're not that great, but they get the job done at a cheap price ) with an alpine 500 watt amp. I was happy with this setup until it quit working a couple weeks ago The amp just cut off, and I haven't been able to get it back on (I checked the amp fuses and the in-line fuse). I think the amp is fried, but I'm taking it to get checked out in a couple days. If it is fried, then I'm going to use this as an opportunity to upgrade. I'm thinking about getting an 18" Fi BL sub and possibly an AQ1200D (unless you think I s…

Just upgraded my headunit now have the Pioneer DEH-P610BT it looks great, and I've always loved pioneer headunit. Anyone have this headunit? Opinions on the microphone and bluetooth? http://www.pioneerelectronics.com/PUSA/Car/CD-Receivers/DEH-P610BT Can someone tell me which frequency I should have for my subs on the radio??? I was always told 80hz is good.

i have a 12in SSD, hifonics 1208d amp (i know, i know). i have the hu settings as follows: sub level 10 out of 15. bass on 0 (-7/+7). then on the amp the bass eq is set around halfway, and the subsonic is set around 27-28 i believe. when i have the gains about 3/4's and the volume around 20/35, i start smelling WOOD. im like 95% sure its wood, and not glue from the sub. but i haven't heard of anyone else say anything about this. am i just a noob or what? im afraid to turn mine up cause of this. also, how much of an effect does all this have on the battery and alt? i have all stock wiring and plan to do big 3, just haven't got the money yet. i baby it most of the time. if…

i finally did the big three today... and omg my voltage jumped up from 12.8 to 14.1 with the engine on.. and under load still getting 12.8 only 70 amp alternator and stock batterys and 8 gauge wiring the old ground cable was so ugly, it was soaked up in motor oil where the terminal bolts on to the engine mount and up at the top where the connector goes to the battery it was corroded with acid dust... (shoulda taken a pic of it before i threw it away). for the grounding from the engine to the chassis i bolted it to the long screw that screws into the alternator and then sanded off some paint and grounded it to the chassis. then for the + battery to alternator i ran the …

so, i tried searchin...but said i cant search for "big 3" because of html codes or something. but i was wondering, about how many feet of 1/0ga did you guys use to do your BIG 3? i ask because i wont have my car untill next week and im gonna go ahead and order my amp kit, wire etc... thanks -jonathan

well my friend bought subs, an amp, and a box from bestbuy. so i told him to let me install it but he said his neighboor has alot of experience (which wasnt true). so any way the guy hooked it all up. he did a nice job on the electrical wiring but when wiring subs to the amp he ran the wires in series which presented an 8ohm load and the amp isnt made for 8 ohms. he was supposed to run them in parallel. im not sure y it worked but it did. then my friend said the amp kept shutin off after a few minutes of play, but then would turn back on in about 7 seconds. but my friend kept on bumpin for like an hour. then i went over there today and rewired the subs in parellel and we …

well here are some gut shots of my new mids and highs amp. this will be part of an active two way front stage.

Has anyone ever heard of their wiring? I've been looking at it because it was so cheap. It's on 1800woofers and I've looked at welding supply, I'm debating on which one to get right now. Thanks guys

So I have been browsing around for some decent amps to push 4 18" BTL's and cant make up my mind. Does anyone know if the Soundstream XXX-6500D amp is any good???

If you have one post up your opinion please.

just got my amp. in the box it came with a paper that says "Total Maximum Power Output: 930 watts." can anyone explain what exactly this means? like is it at 2 ohms at a certain voltage or is it the 2 ohm and 4 ohm ratings total added? or what? thanks!

As the title states Would it be possible and worth it just to use my cap as a voltage meter? I know caps are useless but i already have it and i dont want to buy a volt meter when i have one on my capacitor. So do you guys think it will be ok, iv heard that sometimes caps can mess up your electrical but not too sure on how caps work and what there designed for. Any info on what to expect would be great, its an easy hook up process and would like to use it if it doesnt mess anything up, thanks in advance

Hey guys, I've got 0 gauge wire running the length of my vehicle, but my amp accepts up to 4. I slapped on some reducers and realized they were too close for comfort, so I heat shrink tubed each post. Although they're on there very solidly, they're still sketching me out a bit. What do you guys think? Should I go for some distribution blocks or something instead? Been a pain in the rear. Running ~1500w Pics:

i have had a couple pioneer 980's that had ground problems, then on the 3rd one i had for over a year with no problems. Now i havent had a stereo in almost a year ( bought a bike and never drive truck), now i am putting stereo in truck. I would like the new 800prs, but have still read of many people having trouble with pioneer ground problems. What headunit does everyone use comparable to the pioneer? Locally, only choices here are pioneer, very few being premier models, alpine, and some lower end kenwoods. thanks for help

i've had my system hooked up for several months now and just decided to add a rockford 360 line driver. i hooked it all up with the remote wire to the rockford 360 tied in with the remote wire to my amp. as soon as i started turning it up my amp went into protect mode. so i took i guess at that me adding the remote wire to my amp did it. so i moved the remote wire to one of my secondary batteries just to see and it still throws it into protect mode. the voltage doesnt drop it will just go itno protect mode. any ideas or suggestions? just incase you need to know what i have system wise 2 18'' HDC3 audioque DC power high output alt 3 batteries in the back (2 kintik HC1200) …

I was doing some thinking.. Taken from http://www.rockfordfosgate.com/rftech/wire_calculator.asp quote: Because music is dynamic in nature, it will be easier for the amplifier to reproduce than test tones. Our testing has shown that it is typical for an amplifier to consume on average roughly 50% of its maximum input current on such. If it is consuming 50% of its max input current on average, isn't it correct to say that when playing music, the amp might have peak outputs of up to 3000Wrms, but on average, might only give out 1500Wrms (over the length of an entire song).. so from that theory, isn't a 3000Watt amplifier better suited to play a 1500Wrms sub?? thoughts?

I have always crimped my connections as they mostly are 8 awg or less. Moving to large wire I have found crimping to be a royal pain in the a$$. I was looking at soldering as a nice option but I have only ever soldered water pipes. Is the process and technique basicly the same? Flux the wire and inside of bass connector, heat connector, insert wire and place solder around the edge of the wire so that it is pulled into the connector? Any help that you could provide or tricks of the trade would be great. Plan on upgrading the Big 3 this weekend and some under the hood wiring. Thank you.

Hey guys!!! I bought an alpine cde123 and it says it has 4v preouts before clipping. Well I am wondering why when I measure at volume 23(at 24 the speakers start to distort) it only measures .188v, I had to max my amp gain out to get it to play full tilt. Even the the amp clipping light doesn't come on when it's up all the way? What could be the cause of this?

is there going to be any auidible difference between the two amps? and how much more power is the t1500 gunna suck out of my system? will be used for a 15" XCON
