i have a hk-802sx, i have 4 L7 15s D2 and can wire 2 Parallel/Parallel for .5ohms witch the amp can do 2200wrms x 2 or i can leave the current way all 4 wired Series/Parallel @ 1ohm. i was wanting to try it at .5ohms but b4 i take all the subs out and rewire i thought id ask and see what ppls thoughts on this, pros or cons???.. any input would be great.

I went to Advanced Auto, their load test doesnt do ampers, 1st with car off all electric off: advanced auto print out battery test 12.82V measured 1256 CCA rated 758 CCA Temp 21deg F While stating: starter voltage 11.74V 0.0A time 625mS dipped to 10V running: Charging system test no load 14.62V ---A loaded 15.58V ---A ripple 37mV Went to O'Reilley's Load test 74A

I figured this is a great place to post this. Anyways. . . My current occupation involves a great portion of the automotive electrical field. I have access to a myriad of 24V alts, and I'm wondering how feasible it would be to make some 24V amps. I would love to have half the current draw, but I don't know about the 24V electronics and interference between them and the 12V system the other accessories would run on. I have a guy I'm coordinating with right now on the amplifiers, but I'd like to get some more input. Thanks!

ive seen people around here with them. where did you get yours and could you estimate a price? i have found some for $370 and $380. just wondering if there were any cheapers ones out there withought sacrificing quality. Thank you, Matt Cusack

Hey I wanted to know if I could get some help for a friend. His car is a 98 Toyota Avalon and he recently bought a 250amp mechman alternator. He switched out his old alt for his new alt(Everything on the new alternator is a plug and play), revved the engine made some minor positioning adjustments to get rid of the squeeky loose noise. We went to a bank to get some money for my brothers install he did. The battery was dead for some reason. So we thought maybe the remote wire for the subs was touching the power wire while in the bank for so long. That wasn't the case. Anyways we got a jump and headed to a auto performance shop to put my brothers new muffler on. Well on the…

throw out some budget amps thatll do around 2500w rms @ 1 ohm daily, will run @ .5 or whatever if its stable daily...its for my 15" mts...i have 4. i know the power acoustik a3000db is rated at 2300w and doesnt even do that, but i heard they are .7 ohm stable daily, does anyone know what these amps are capable of? hifonics? help!

Eyh, Got a great deal on dual DD3515 2ohm dvc subs, so i'm planning on running them at 2 ohms, Been looking at the kicker 2500.1 amp but is there any more good altarnatives out there ? Thanks, Denven

I finally got my DC Power Inc 250amp alternator and switchable MLA module installed. I now have 250amps (140 at idle) available at 15.6 volts sweeeeeeet. I just have to clean up the wires and I'll start a build log with pics. Now I need to run power wires to the trunk and start building the enclosure and kicks.

like my title says, i did some trading with a guy and hes sending me his 260amp iraggi alternator. its just over a year old and he has only been using it to power a saz1500 for a few months. is there anything i should be on the lookout for when hooking this up? like is there any electrical upgrades i MUST have done before i can hook it up? i have all 4 gauge wiring now but i am switching to 0 gauge before i try to push anything big. i only have a reg. car battery from napa right now but i plan on getting 2 deka 1800's (from Alan427 when he decides to sell) in the future to run as well. anything else??

Hey guys just recieved my Alternator today from Singer Should hope to install it over the weekend let me know what you think? Its going in a 2004 f250

has any one ran power to a 2d blazer, i all ready ordered 25 feet but im wondering if i will need to get more, i am running one line from pos to pos on my powermaster and and the pos to amp and hopefully use it for a ground too, any one from experiance think 25 feet will do it

Hi im looking to buy two Fi 12" SSD's and want to hook them up to only one amp, is it possible to wire them at 1 OHM?

ok looking 2 a good 2k amp narrowed it down to pca200d,us md-3d or will have to just settle for a kicker1500.1 and be short some watts. whats ppls opinion first hand on these amps thanks

Would I be able to run 2 alternators on my 2003 Lancer if i made the bracket and had room for it? If so how would I go about wring the second one in, or could I have it wired to just my audio battery ?

Newb here. Im thinking of getting a rear battery in my tahoe. I've done the big 3 in 1/0.Some people tell me to run the positive wire from front batt. Others say run it from from my alt to rear batt. For grounding some say go from negative on front batt to negative on rear batt. Some say ground to the chassis. Some say get an isolator and relay. What am I really suppose to do and do I really need an isolater and relay. What do they do

Im getting a second battery soon for my truck and i was wondering how to install it. I know you wire positive to positive ans neg to neg but after i wire the batteries together do i run a wire from the second batteries neg to the ground spot on the amp? And i just wire the 2nd batts positive to the power on the amp right? I also plan on grounding the alt case, and both battery negs to the frame. Good idea?

Ok I bought a 2nd battery for my car and wanted to know if it would be ok if i ran 0 guage from front bat positive to rear bat positive. and just ground the second battery in the trunk. I'm also doing the big three.

I picked up a 2nd battery today. Wired it + from the front battery to positive on the back battery, Then positive from the back battery to + on the amp. Then with the front battery negative disconnected I connected negative from the back battery to ground on the amp. So with the car being shut off and the front battery negative disconnected my amp is on, I basically have constant power? What am I doing wrong? Do I have to connect both front and back grounds to complete a loop or what? Is there any chance of blowing my amp or anything else by trying it? My remote wire for the amp is hooked up to the deck n I jus don't get why my amp is constantly on when the front isn't ho…

I have a 08 xB with a regular wet-cell in front. I'm going to run a Sundown 1500D. I can get a pretty good price on a Kinetik HC600, would it make a difference, or should I save my money?

Just installed my 15" bl running off a bc2k. Stock alt, big 3, and a gold battery up front (don't remember the brand but it was the best I could get from advance) voltage is ok until I'm full tilt. I was looking at a cheaper Xs power battery but there still $150. Any other brands I should b looking into? Looking for a cheaper price but I don't want a shitty battery

I got the wiring already so would a 2nd run benefit me? I'm running a 240a alt, xs power d3400 up front, big 3 and 2 kitneik hc2400s in the back. Soundqubed 4500. I just hear many different things and not sure if it would be worth my time. Thanks guys

okay im running my subs at 2ohms but my amp isnt 2ohm stable, its a crunch 1100wat i kno someone selling a sony 1000watt 2ohm stable amp, is it worth it? he's selling for 35 bucks, (he needs cash quick) but is it worth it?

Hi. I'm looking into head units and came across a Pioneer MVH-P8200...I noticed in the specs it states 2v output, is this too low? I'm planning on running a sax-125.2 and 1 or 2 sae-1200dv2 (eventually just one more powerful amp). How would this affect power output at the amps and gain settings? Thanks.

2volt headunit vs 4volt headunit which is better? what are the benefits of a high voltage sub output? I currently have a 2v alpine that i'm thinking of replacing I'm thinking with my current setup that I can use a little more power but idk If i get a 4v, will i have 2 retune my amps? Will I end up just turning my amps down with a 4v, and have the same results as b4? Would it be better to put that money towards a big amp? (money is rare)

so im gonna be pushing 2 fi bl 15's with flatwound coils and the cooling option. so... 2x hifonics brz1700's http://www.sonicelectronix.com/item_23547_Hifonics-Brutus-BRZ1700.1D.html or a hifonics colossus http://www.sonicelectronix.com/item_32990_Hifonics-Colossus.html ive got strong electrical so feeding power to the amps wont be a prob thanks everyone!
