Amplifiers / Head Units / Processors / Electrical

I have currently a 250 amp fuse on my wire from alt to battery, would upgrading to a 300 amp fuse help or hurt in anyway? Does a bigger fuse give me more amp current to the battery (off a 180 amp alt)?

Finally listened to you all and got a cheap charger at Walmart, 6A charge maintainer, microprocessor controlled, 72W 6amp fast charge 4A medium and 2amp slow 6V/12V automatic. Hooked it up and let it sit over night. In the AM the remote unlock didnt work so I knew it wasnt charged. Looked at the charger and it said full charge. I unplugged it and tried to start it, dead. Reconnected, put back to fast charge, it started...the fan revved higher and higher then shut off. I unplugged and reset, put on slow charge, fan stayed low reve so I left it for 2 hours. Came back, said full charge, but was dead. Gonna take the cheapie back today

Will it make a big enough difference in upgrading quality of my midrange amp but not power to be worth it? Will it make a difference in the sound of my? Or is 400 watts 400 watts and switching amps to a higher quality amp of the same power not make a noticable difference?

Is the tsunami DB440 amp any good? What other amps would be comparable?

Ok i shoulda took pics, but hey.. So i have it hooked up @.5 ohms and well yea this system is alot louder than my PA3000db. but i have a slight problem, i'm guessing its an electrical issue, but... I can only turn the system up so far before a big bass note hits and its like the amp goes into protect and then comes right back on, say 2 secs later. SO is it wiring or electric? I'm going to hook the battery charger up to my car to check but any ideas? IT wangs dont get me wrong, but i just cant turn it up louder than a certain point..

The new SAX 200.4 makes me feel like everything I ever bought has been wasted money! I hope this isnt going to be considered spam. But I just had to SCREAM IT AT THE TOP OF MY LUNGS! Come to me SAX 200.4 . Unbelieveable. Just had to tell someone.

believe me i know this is a stupid question but i had an argument with a guy from a mechanics shop and he doesnt believe me: if you have 2 DVC 1 ohm subs wired in series then together to come to a 1 ohm load and run that to a monoblock amp that is rated at 1600 watts rms @ 1 ohm, does that mean each sub gets 800 watts each or do they both get 1600 watts?

So i didnt realize till after i bought my amp its a 2 channel amp instead of mono. So heres the wiring im going to do http://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/2DVC_4-ohm_2ch-br.jpg Now i cant understand my amp specs as i dont understand how to fully read them correctly. But there this 300X1 @ 4 ohm 500X1 @ 2 ohm 750X1 @1 ohm So my question is in the wiring i did how many watts will each sub get? Thanks

The xtant is a 3 channel amp 75x2 + 150x1 at 4ohms or 150x2 + 300x1 at 2 ohms. The system is going in a Ford 350 dully. The doors have 6x9's. My original thought was to run ID's 2ohm 6.5 comps in the front and doing nothing in the back doors. Then running a single IDQ 10" or 12". Also thought of running 2 sets of 4ohm comps or coaxials in front and back doors. I haven't decided on a HU yet. Mainly just looking for one more geared for SQ and one that will run an ipod. I have plenty of time on this build and am not commited to anything but the xtant 603x. Any thought's would be appreciated.

hello everyone, I recently change all my system and after the installation i get a lot of engine noise and alternator noise. the install was like follows: Alternator: a 250 amp Ford alternator modified to use a voltage regulator, so it generates from 10.5 to 18 volts. Power wire: upgrade to 0 gauge from alternator to main battery, to second battery, to capacitor, to distribution block. Ground wire: upgrade to 0 gauge from alternator to engine, to chasis, to battery, to second battery, to capacitor, to distribution block. Amplifiers: 1 Memphis st-1600d to subs (2 10"Ascendant Audio) 1 Autotek 500s to mids (4 5.25" Crossfire) 1 Pioneer Gm630…

can some one give me names of companys that make HO alternators? and a website or # cause iam in the process of getting a 220amp one.

I've searched here and there, been to the12volt, etc etc etc. I'm still a little bit confused on how exactly to wire three amps with one remote wire. I've photochopped something from the12volt to illustrate my issue. Not much of a photoshop, but you get the idea. The question is this: Do I splice each remote wire from the three amps into the same single wire coming from the relay? Thanks for any advice.

120a2 just arrived, adn I plan on picking up a mint 800a2 this week

Blue one: http://tinyurl.com/ybem7ro Red one: http://tinyurl.com/ybndc95 just ordered mine.

this forum is alot better to get answers from. so i was wondering where sould i put the amp? on teh sub box? or on the carpet under my back seat in the van? does it matter? and should i look to get a CAP?. i have a 130AMp alternator and a Die hard Gold battery, and the amp is a 1200 concept. with 2 gauge wiring and the fuse i dont know what size? either to choose thanks alot i will post pics when i get it all which should be wensday next week.

I just got a sundown 3000d and it since it can run from 10 volts to 18 volts, ive got to thinking of a 16 volt battery setup for the future. But how would i do that and keep the rest of the car that needs to be 12 volts stay at 12 volts?

I've never bought all the wires and stuff separately, I've only used those amp install kits. Im trying to figure out how much it will cost to wire up my amp and stuff. Orion 2500D. I'm going to need an alternator, I was thinkin a universal alternator... I can make brackets for it, we have welders and stuff and I can weld. Reason why is I have an engine coming sooner or later for the truck, and its a different engine than what is in it. So I'll just make a new bracket for the other engine. I want to run the secondary alt seperate than the existing charging system, and have it dedicated to 1-2 batteries and the amp will run off those batteries.. Not sure what batteries eit…

So I have a Alpine ute52bt that is cutting out whwn I turn it up. I first thought it was a connection So it was checked. Tried to move the ground from factory to bear metal to battery and it still cuts out once I start to turn up the volume. do you guys have any other ideas? Sorry for the short post. My set up is the deck listed. A pair of i65c and a pair of infinitys in the rear. Nothing follows.

what would it take a Capacitor? Or another battery in series?

So last night on my way home from work I was listening to my stereo and all of a sudden the H.U. shuts off and then restarts(Alpine 9884). I installed the H.U. last year in November and never had a problem with it then about a month ago I put in a Sundown SAZ-1000D and a Fi 12" Q. Never had a problem with my H.U. turning off before last night. I dont know if the cold had anything to do with it. It was around 30 out and snowing. Today comming home from school it was listening to it seeing if it would shut off and it never did then comming to work a few hours later it started doing it again. I have yet to do the big 3 and my voltage drops pretty good. Im driving a 97 bla…

chit fudge chit driving home from school today, music playing next thing i know my truck starts randomly slowing down and my ABS light is blinking. THen i see my voltage meter is droping lower than usualy with the beat. I turn the system off and everything is good. Turn it back on and same problem. Im pretty sure my alternator just died on me. how this relates to the ABS randomly comming on i dont know. Glad my 4 year old battery had the life in her to get me home, Hopefully it can get me to the parts store to have my battery and alternator tested. If it is the alternator, while im paying $150 for a new stock replacemnt, i'll probably pay $100 more tops for a Hight Outpu…

I don't know if you guys even talk about video here, I did a search but didn't find anything. I was wondering what are some good quality 7" or 6.5" headrest monitors? I am putting one in my dash and have been looking at dei and sony. Can't find many companies that make a plain monitor w/o all the buttons on them. Eclipse has a nice one but not shipping till may or june and clarion's are nice but has buttons on them. I was looking at farenheit but I heard they are not good quality and customer service in near zero, and this was from one of their dealers. Also looking at visualogic or something like that, at a dealer but they come with the headrest only. any help would be …

I am going to be running a Pioneer 80prs with front and rear RCA output for my front stage. I am going to have two amplifiers for my front stage. How do I go about my lack of RCA signal ? I know I can use a processor but is there another way to go about it and not be poor quality? Thanks for any help

well i got a weller 140 watt soldering gun, and some rosin core solder. I tried to solder my 1/0 to a ring terminal for one of my grounds, but the solder just balls up and doesnt stick to the ring terminal. i dont think im doing it right. lol. any suggestions?
