ok im about to hook my system up an im gana put 2 batteries in the trunk there gana be in mdf boxes mounted to the trunk. do i need anything special to do this or can i just put 1/0 wire from front to back with a fuse by the front batt and one infront the back batt.

ok so i have a 2006 chevy colorado and im going to be getting a 270 amp singer alternator that comes with an overdrive pulley that adds 30-40 amps. and im pretty dead set on getting an xs battery for a secondary battery and i was wondering what size or model i should get. and i wanted to keep a battery with top posts under the hood and was wondering if i could go with like an optima yellow top under the hood or if i had another option for under the hood? ill be running a crescendo bc3500 on two fi bl 15s.

My H/U only puts out 2v. Figured this could help so I bought one. Im tryna set it to about 5V. Got the cover off and everything. But how do I check what voltage its at? I put a DMM on the outside of the rca plug and it stayd at 0. Put the prongs on the inside and the numbers went crazy! What am I doing wrong? Do I have to have the LD installd and the rca's hookd up before adjusting the voltage?

I ordered an Fi Q15 with BP Power option. Would a Sundown Audio SAE-1000D be a good match for this sub?

Am using a US Amp MD.3D amp. I got a HO alternator from Nations that push out around 140 Amps at idle and 230 Amps max output. I also have a 2 Farad cap and a battery that is 1000 cranking amps (CA)and 850 CCA. Will this be enough to run this amp without it going into PROTECT mode or shutting off due to the lack of "juice"? What is the "BIG 3"?

I have been looking at the clarion eqs746 dash mount crossover. Not sure if I like the idea that my head unit has 3 rca outputs and the EQS746 only has one input. I am interested in installing a crossover but was thinking of looking at a trunk mounted model. thoughts??? Opinions???? model suggestions for the trunk mount models??? have been looking at Audio control and I have a MTX RT-X02i used in the 90's looking to improve my current sound output. I feel like I am missing something just haven't figured that out yet.

any of you guys have any experiance,opinions on this amp. http://www.woofersetc.com/p7750/DTR11700D-...s-Amplifier.htm ive been a fan of Soundstream amps(ive had the PIC 1.1700d and loved it)and really like the way these look.plus i found it on ebay for less than 300 shipped. i plan on running it on a single Fi SSD 18. so feel free to post up you opinions/thoughts.

after seeing some reviews on the audiopipes i was thinking about buying one to see what it really can do. but i wont buy from a dealer that don't have a decent warrenty or a authorized dealer. i saw some rickies electronics or something... the 30001d they said it was 15inches long... i keep getting these "dealers" with false information.

ok i have this amp and i want to run it at 2 ohms how do you wire 4 6x9s that are 4ohm to make an overall 2ohm load while using all 4 channels? http://www.onlinecarstereo.com/CarAudio/Pr...ProductID=19342

well im about to start my new build some time next week hopefully and im trying to get my electrical squarred away this weekend so here it goes. i recently recieved my new amp (cactus 5kw), and i know it is going to need alot of juice so my plan is to 1.) upgrade my starting battery to a decent car audio battery (everstart maxx, walmart style now) 2.) do my big 3 in 0 ga (haven't done that yet) 3.) run 0 ga to the trunk 4.) one battery in the trunk for sure (d3100) and possibly another if i need it. so far my knu koncepts cart looks like this: 2, 0ga amp kits(for the extra wire, 250amp fuses), 4, battery terminals, 2, 200 amp fuse(for alt and rear batt.), 10 foot of 10ga…

What are ya'lls opinion on Panasonic head units??? I can get this model for free from work through reward points.

I know that the 3500d is on presale, how does the presale work? Were can I order them and how long does it take before I would receive them.

What are you guys' thoughts on this? It is sort of temporary give or take on how much I like it, I don't like the looks too much but it seems like its fine. I like having the noticable volume and channel changing button also. The USB I have read that you can plug your iPod through the USB and it should work (if it doesn't I have a flash drive or can get a bigger one for ~10$) and it plays cds. I have an iPod touch and I haven't been able to use it because the wireless ones dont work for chit (and differ in each car), I have no tape deck, and all I can play are cd's. This unit also has 6v pre-outs with front rear and subwoofer RCA inputs. (I can use them for my subs) I als…

Hi, need a small powerfull amp for one ssd 10 dual 2. I think about one Fosgate PUNCH P1000-1BD or one Soundstream Stealth Series STL1.1200D. The Punch is BD class and has 1000watts and the soundstream ab class and has 1,2kw... The amp has to be stable and powerfull but most importantly SMALL..... Whats the better choice?? Patrick

I am never one to cut corners, on the flip side I am one to over build. I am ditching Iraggi alternators cuz their service SUCKS and I am going excessive amperage. I will be getting another HO alt and 2 more big AGM batteries and doing some more runs of ott. 1st off, do you guys recommend I get a missinglinkaudio voltage regulator? Anyway, should I get dual 4 ohm XXXs for the VAN and go 2 ohm, or should I run dual 2 at 1 ohm since I should have good electrical to back it up? I have heard stay 2 ohm, and I think that is what I will do. It's already too loud as it is 99% of the time.. my ears hurt and get numb on a daily basis and I know it's stupid. But when i'm showing o…

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…

So my friend bought a Lanzar MaxP1200 (for some reason) and he proceeded to changes his (3) 30A fuses to (3) 40A fuses because he said that the bigger the fuse the better. Now, in my head it seems like the amp was rated at 90A for a reason but i dont know shit about fuses. So, by changing the fuses, is he screwing things up?

http://www.crutchfield.com/App/Product/Ite...A465&tp=115 Link to the amp. I need an 4 channel amp that is 2 ohm stable and has variable cross overs. My fronts are Infinity 682.7s with stock 8" midbass in the doors. No rear speakers. I'm actually happy with the sound using my HU to power the 6x8s, but it is starting to die since the speakers are 2 ohm and the HU is not 2 ohm stable. I also want to be able to control the cross over points of my midbass speakers better.

I have a Rockford Fosgate punch 501s 1500W amp These are the specs- Bridged Into A 4-Ohm Load: 500 watts x 1 Per Channel Into A 2-Ohm Load: 250 watts x 2 Per Channel Into A 4-Ohm Load: 125 watts x 2 Im really interested in buying a single gcon 12 and was wondering if it would work with this amp and if so does anyone have anysuggestions on how i would wire it up to sound good. here is a link to the Gcon 12" http://store.soundsolutionsaudio.com/products/gcon-12-sound-solutions-audio-12-750w-gcon-series-subwoofer.html let me know what you think Thanks..

So who has a new aq3500d.1 and how do you like it? i cant stop drooling over it and for the price i want it. Does it do rated or more? I just need some more power... welll.... not neeed but i sure want some hahaha

just a quick question, is it possible for a amp to be "too cold"?

Hello, iv just been looking around for a battery and oddly enough i found a marine AMG battery in my dads garage. Its a Cabela's Advanced Angler "Group Size 30" battery. Heres a link showing all of its specs. http://www.cabelas.com/product/Boating/AutoBoat-Batteries-Chargers/Marine-Deep-Cycle-Batteries|/pc/104794380/c/104698080/sc/104446080/Cabelas-Advanced-Angler-AGM-Batteries/727395.uts?destination=%2Fcatalog%2Fbrowse%2Fboating-auto-boat-batteries-chargers-marine-deep-cycle-batteries%2F_%2FN-1100564%2FNs-CATEGORY_SEQ_104446080%3FWTz_l%3DSBC%253BMMcat104794380%253Bcat104698080&WTz_l=SBC%3BMMcat104794380%3Bcat104698080%3Bcat104446080 Now seeing the amp rating an…

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...me=STRK:MEWN:IT Been doing some research on this for lil while and the retail on just the HU is $2200. I think I made out okay!

Do any of you guys know what's the maximum unclipped output voltage for a PG tantrum 1200.1 at 3 ohms?

Lately my cars "radio" fuses have been blowing not the fuse on the hu but the cars radio fuse. First time the fuse blew when I first turned the car on.. Which was weird since I never had a fuse go out on me since I had the hu a year or so now. So I went and pick up more fuses (8amp Volvos standard) put one in worked fine at idle went down the road turned the hu volume up half way and just as the bass hit the fuse popped!. So the next day I took the hu out looked around checked ground power etc nothing was wrong ( besides a big mess Of wires and rcas) placed another fuse in with the hu out and banged on it for 20mins zero problems. Put it all back in. Worked perfect for 4…
