Amplifiers / Head Units / Processors / Electrical

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…

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?

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.

Does anyone have any experience with the AQX3500's? im planning on running one on 2 AQ HDC318's copper coils. Id like to run it at .5 ohms, will it become a frying pan or will it be ok.

How do you guys do it and still get the door sills back down? That wire is so thick I cant get the plastic sills to snap back in. Also for those of you running the amp behind the rear seat how big is the amp? I have a sundown 1200 v2 and Im starting to wonder if its too big to fit back there. I cut out the rubber to fit the amp in but Im wondering if when I put the seat back in if it wont fit. Id like to know before getting it all done.

I have a DC power H.O. alt and big 3 done with a kinetik hc1400 up front and a hc600 right next to amp with 4 awg connecting to my SAX-1200d and yeah my voltage is fine MOST of the time but it seems like on CERTAIN random songs with a perfect note my voltage still gets awfully close to 12v occasionally.. HOW many batts you guys running and on how many watts rms you pushin? Since Im thinking about upgrading to an Xcon 18 > over my current 18 ssd, I will most likely be upgrading my amp to a 2000rms amp or something close to 2k like AQ/AP/Hifonics and Im wondering if adding a battery or 3 will help make a difference because Im NOT upgrading alts again.... 1200rms seems w…

My sister is looking to add a sub and amp to her 07 charger. She came to me and I showed her a few things. Prices are too high. I'm trying to get her into a single 12" ia lethal injection or fi Q possibly icon. So we're looking at around 1000 watts rms. showed her the sundown 1000.. Too much ($289). What do you guys recommend in the $150 or so range for an amp? Is something of fair quality able to be had new for this price or is used the route I'm going to need to take? Just looking to toss around some ideas and see what others have had experience with. Sub choice is pretty much set. I have a friend with a single 12" fi Q and she liked how it sounded. Absolutely hates ho…

i have two fi ssd 15's running at 600rms each on a pheonix gold 1200.1 and it just isnt pounding enough for me i wanted to give the fi's a little more so i was looking for a new amp. i wanted to give them anywhere from 800-1000 each. i came across an amazing deal and got a brand new opti4000d which retails for about $900-1200 and i got it for $300. i just couldnt pass it up.. i know there are mixed opinions on the opti's but for the most part i hear they are decent. now heres the question.. 3000 watts at 2 ohms is too much to give to my ssd's. what do you think i should do? im totally down for new subs.. or i can sell the opti and make like $500 for a new amp. i love the…

guys i was wondering about a system that has say 10 amps & a couple of processors if the remote wire voltage from a typical deck will be sufficient or safe to turn on all of these or will a relay be needed to help boost the turn out voltage ? what is usually the voltage out from a deck ? what voltage is required for amps or processors to turn on ?

im a noob,and i keep hearing about amps "clipping" what does that mean?

Few days ago i went to pick up my suv from my aunts house since ive had it there stored for few months. On my way back i notice my “RE XXX” tweeters stopped playing, so i thought for some reason they got damaged not knowing why when they were playing fine before vehicle being stored. I removed them and tested them just incase a wire was pinched and they didn’t play so I tossed them. I installed some new alpine type x tweeters yesterday that i pulled out from my truck and tonight on my way to work they stopped playing, it looks like they also got damaged. Im using a pioneer avh x4700bs on active mode, highs setting on 5k,12 slope and have my hertz hdp4 setting on full. I …

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

I've always been a fan of getting an Alpine H701 with a W505, but I am scared that with the H701 being discontinued I may never find one. So I'd like to find some more options for what is available and capable of 3-way processing. Also would be nice to have a collaborative list here for those to reference to.

I've narrowed my choice down to these choices. Mechman 270 DC Power 270 XP I was wondering if the extra 35-40 amps at idle is worth the extra $150. I'm only running one AQ2200D, and I don't have an endless pile of money. I'm almost certain what the responses will be, so I think I'm leaning towards the Mechman. Let me know!

I bought my Alpine CDE 9881 from a pawn shop for 50 bucks back when I had my old car and I recently got a nissan maxima. One thing I rly hate, this headunit has no aux in front or USB and most important, it doesnt work with a steering wheel adaptor. I have had a few people offer me $65 for it (is that a decent price?) and I think I might sell it and get something a little better. I know crutchfield is usually over priced but their headunits seems fairly priced, especially since they give you all the install stuff and save me around 30 bucks. I'm not going to do much with this headunit, just listen to music on my ipod. Idk how to tune, etc. I'm also running a passive setup…

What does what better then the other and which should i use for a 1500kW set up and a 3000kW set up? thanks

Hi Guys, Are the Audioque amps ( 2200, 3500 ) good amps or not ? I what thinking maybe someone out there has tested one the website numbers look good.

Fuse Holder with 300amp fuse-- Batcap Rca's Speaker Wire 5 0/1 gauge o rings Can someone help me on where to get this.

So I'm going from Kansas city to Cali once I got to Denver I notice that my amp is getting hot not hot hot but a warm hot my apt is at 14.9 volt and I'm not playing it at all just listen to music but the amp is cut on

i can get both for about the same price. i know the 8053 can run an active 2-way + sub. anyone know what sort of crossovers the alpine has ? which one to get ? i honestly don't have a clue as to which to choose...

I recently purchased a 12 inch dcon and was wondering if it would benefit from a class A/B amp or if I should just buy a class D. What do you guys think?

k im looking to replace my headunit with one that has higher out put voltage whats a good brand and modeal i should look at i heard some of the kenwoods are good or would it just b better to get a line driver for my system
