Amplifiers / Head Units / Processors / Electrical

I have a soundstream XXX4000d is this amp worth anything? I have it currently on my 12 inch warden and I am not feeling the power or seeing the numbers that I should be. Is this amp junk or am I missing something. I have 3 batteries, a 220amp alt and the dual 0 gauge inputs going from the batteries to the amp. The sub is in 3 cub with a slot port tuned to 47hz. I am only at 145.2db and we tuned the box for the rez freq of the car.

Whats up SSA Forums, Im looking to replace the alternator on my 2002 BMW 530 ASAP with an HO Alternator. My search online and in person has not been too good, so i was wondering if any of you guys could refer me to a person, website, or shop if it's close to the Raleigh/Durham area in North Carolina. Thanks

Okay, so i've been away for a min but i've finally got me another vehicle with room for a system, and my question is as far as opinons go what is the best head unit for around 400 or less that is internally amplified, thanks for the help in advance!

We've created a blog to clarify a lot of questions in this market and here is just one of the many we're going to have. Enjoy: http://blog.dcpowerinc.com/2010/09/05/the-benefits-of-high-voltage/

Soon i should be running 2 saz1000d's strapped for 1800 at 2ohms in my isuzu rodeo(60 amp alt) big 3 done in 1/0. I have both amps already and i also have one stinger spv44. I will be buying another batt soon, probably a deka intimidator 9a31. Now my question is, which one should i use as the starting batt and which as the batt in the back? im not sure what i should do. I wont have a h/o alt for another couple months also. I know thats probably not enough to run the amps at full power, but i will keep the gains low until i get a h/o alt. thanks for any input! -Max

Well I have finally gotten around to using the MB Quart PXD-213, I have had them sealed in box brand new for 6 years now. Fantastic product just never used them. The question I am having is this and it may sound like a noob issue so please be gentle. I have a phenix gold 250.2 running them, have 12 gauge speaker wire in lengths less than 3 feet from amp to crossover, now I don't understand the installation diagram cause the damn thing is in german. or deutsh. so here is the issue, it says to run biwire from the amp into the low input and the high input, I have them wired just to the high input from amp and they sound phenomenal. now the issue is this at high volum…

I have spent most of yesterday checking connections and redoing them. Before that the only thing I did was actually put a crimp on the main remote line running to the amps as to how I had them before just twisted together and taped. before the crimp I rarely got that THUD sound and now it happens every time I take key out of ignition without turning off radio first. Heres what I have kenwood HU running to, clarion EQ, from there to one Rockford P1000-1bd and a P400-4 I guess I'm being lazy and should just undo that crimp but I think that crimp is stronger than just twisting line together, could I be wrong? could I have done the crimp wrong?

whats up guys and gals....i am installing 2 18" fully loaded btls being pushed by 2 us amps md-3d rated at 2000 dont think power rating for the question matters but oh well..anyway the question i have is how to run the subs on the amps so i can use 1 bass knob from 1 amp and not have to run both...the amps are multilinkable amps just not for sure how to wire...help out thanks alot

So I am looking for some help choosing an amp, but I need help because with my speakers I have the options of making ohm loads at either 0.86, 1.26, 1.5 or 3.43. I am looking to push a minimum of 900 and a maximum of 1200 watts continuous. My absolute price limit would be 250, but the lower the better, I'm actually looking for the cheapest that I can get away with while still meeting my requirements.

2001 Chevy Impala. A friend's car. Aftermarket alternator rated at 220 max, 105 at idle. Overdrive pulley. Had his mechanic install the big 3 with 1/0. Optima Yellowtop 1050 amps. He only has one amp right now. 2 gauge wire running back to a JL 1000/1v2, 2 farad capacitor, and a 500 amp dry cell, running a JL 13W7. All of this was put in his car professionally... which could be good or bad. His headlights still dim, especially on the heavier individual beats. It's my understanding that the ground wires on these cars connect to a thin piece of metal that's simply folded onto another one, and therefore can't really flow that much current. ...meaning that running a dedic…

What are the Pro's and Con's of a Capacitor?

So basically I put the ground wire in the power input and power wire and the ground input, now my amp won't turn on, fuck me. All I wanna know is what did I fuck up or possibly fuck up? Thanks for your help..

Hey all.Was just wondering if my amp (the one mentioned in the title) is able to be daisy-chanied with another Autotek Street Machine 1500 watt amp.Thanks

will a audiopipe 3000d see 1ohm as a daily driver?

i'm curious about a 2600 on a 18'' btl fully loaded dual 2ohm sub, do you guys think it's a decent amp or should i pick up something a little better?

Well I finaly got to mesuring my cars voltage, and to my suprise, my dmm read 14.23 and this is all stock electrical without the big three. I got the voltage Through some cheepo 8 gauge from my most recent system. I wanted to know if this sounds good for a 1kw system. Thaw alternator is 95 amps and the batery is a die hard. I want some opinions if you guys think I may be able to run a aq 1200d whithout any major electrical upgrades. And I am doing the big three in 1/0 cable.

Hey guys, I posted this on 180db.com but have yet to get any responses. I just purchased a new Kinetik HC1800 and when I installed it my car was idling so rough that I was scared to continue with it. Let me explain the install first cuz it might have something to do with it. Had an Optima Redtop that was okay but I kept getting the dimming when pumping the tunes. I then bought a 1.2Farad RF capacitor and it was a little better but not by much. So instead of experimenting with upgrading wires yet I decided to purchase the HC1800. Well, cables were too short to reach the battery connectors even when turned 180 to be a little closer. So I went to the hardware store and purch…

Just curious what all of you guys are running as far as engine belts with your HO alt? I'm running a new stock GM one now, thinking of getting a gates belt...

Can you hook up a set of 2ohm speakers on the front channels and 4ohm set on the rear channels of a four channel amp?

are the hifonics amps still any good would anyone recommend them i had one about 4 years ago and it was stout its in my friends car and still playing. do they still do they still put out as much as they claim

hey all i am looking to upgrade from my us amps xt1600.2 which i recently found out is highly over rated (noob purchase..my bad) to something with a more true rms rating. i am looking to spend about $250 tops and although i know that is not a very big budget i just need something that pushes closer to the 1000rms rating of my ssa icon 12''. i am looking at hifonics brand amps and have come across these two. http://www.audiosavings.com/products/Car-Amplifiers/HIFONICS-BRUTUS-BRZ1200.1D-1200w-MONO-AMPLIFIERAMP-KIT/BRZ1200.1D---XK4B1.aspx and http://www.audiosavings.com/products/Car-Amplifiers/HIFONICS-HFI1500D-1500W-MONO-CLASS-D-AMPLIFIERAMP-KIT/HFI1500D---XK4B1.a…

I am adding a second battery and a bigger amp. I need about 25 feet of 1/0 wire. My question is whats the best place to get it from? Also, I see people not liking KnuKonceptz wire. What is up with that? Is it really not worth the $1.75 a foot they want? Is it better to buy from a welding supply company for about $2 a foot? I know these probably sound dumb, but I've only dealt with 4 gauge in the past, which you can get anywhere. Thanx guys

So I got on it today getting on the interstate, battery light came on, stayed on a few seconds then went off. Put it in neutral, reved it, nothing for a few seconds, stopped reving, light came on a few seconds. Pulled over, put DMM on front battery 14.18. Reved it up, droped to 13.2...stereo off. Checked rear batts, 14.18 running, dropped to 13.5 off, probably would have kept dropping slowly. O'Reilley AGM in front, 2 large O'Reilley AGMs in back 100aH. Iraggi HO alt, the highest at idle lowest peak: 160-180 idle, 200-220 peak.

So my car has been dieing after sitting overnight. It won't start in the morning. I have been leaving it on the charger overnight. I have an Optima Red Top under the hood and a 55ah SR12-205FR Super Rate Series in the trunk. I took the trunk batt out at Autozone and the guy tried to test it and said it was at 10.xx volts and he couldn't run the test with it that low. He said that I have to do a trickle charge on this batt, it can't be charged with a regular charge. Is this true? Then we tested the red top (with the trunk batt still disconected) and it was resting at 12.41 volts and read as a bad batt. The Autozone guy said it should be around 12.45 volts and I should tri…

Looking to get a 40 amp fuse for my sundown 1500d. Looking online I can't tell wether I need and ATC fuse or a MAXI fuse, just wanna make sure I get the right one. Thanks, Nick
