Amplifiers / Head Units / Processors / Electrical

I know you're not supposed to run more than one REM wire from the single one off of the head unit, but I'm kind of (read: really, really) crunched for time at the moment - it would just be a small component amp and the subwoofer amp.

Okay this is the second one I'm posting of this the update is I replaced the 8ga to 4ga and I'm still getting light dimming so far I replaced the alternator from a 2003 highlander and did the big three so I'm guessing the battery is left to replace or do i have anything else to fix before replacing the battery

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

Is it possible that the 900 d can out do the memphis amp? Thinking about going all powerbass. Switched from my f-150 to a xterra. 3db jump to a 144.5. Hoping to get better going with all powerbass. Thanks

Well I have been talking about this and other head units on another forum but i want to get peoples opinions on this one. Eclipse CD7200 mk II Would you use this one for the price? If not which one would you go for? What do you think about it? On a scale 1 to 10 what would you rate it? If it could be out done by another head unit what is it (equal or lesser price)? If you would get a cheaper one, which one would you get? What is it missing? and last what are you guys using? I am looking for blue tooth and and iPod connection. I don't care about hd audio and all that stuff. All of this is going into a 2002 VW Passat without a Monsoon system. So the deck isn't quite a doubl…

KnuKonceptz has a 1/0 CCA amp kit for 60$. Their 4 gauge OFC kit is 52$. I know pure copper is better than clad, but is 1/0 clad better than 4 gauge pure copper?

as the title says I need a downloadable users manual for the cda-7949. Alpine doesn't have them or pac parts. I'd be glad to pay for copied one of you have it. All help appreciated. Thanks, Joe. P

I mean exact wiring for this...i feel like it wasnt done correctly bc we are incorporating the crossovers into the mix. STOCK HU. Rockford Fosgate 3sixty.2 Crescendo 800.4 Crescendo 1500.1 2 sets of Mezzos. 4 tweeters and 4 6.5's Fi Q D2 Im not sure why, but my guys that helped me out with they system incorporated the crossovers into the system. I thought the 360 could be used instead of crossovers. If someone has some time and would really like to help a fellow car audio fanatic out, how would you wire this setup? I would love to see a diagram drawn out!

i work at a shop and have a customer who wanted to buy a large power amp. none of our main dealers have anything in his wattage range. so.. down for sound has a JP53 that calls for 600 amps of fusing... then we have a tara amp thats calling for 209 (music) 419 amps sine. both claiming 5KW of power. 120 - 390 amps of difference is (any way you slice it) a massive change in electrical system demand. why would anyone buy a ...? is tara incorrect? bottom line - im digging into efficiency numbers that ive never really had to care much about when working with 500-1500w JL and rockford amps...

Ok, so the tittle may be a little confusing. Sorry about that. But what I am trying to get a answer for is to know whether or not, 1 watt, equals 1 watt? For example, lets say one company claims 1000 watts rms @ 1 ohm. And some other company claims the exact same thing. Now if we set these two amps up to a controlled vehicle/setup, why would one seem louder, or just plain oh better than the other? Obviously the main possiblity would be because someone is not providing that 1000 watts, but lets say we testing both amps the exact same way, with sophisticated equipment and techniques, to find out that they are putting out exactly 1000 watts. Then what could be the reason? T…

so i sent my money to dominick irraggi for a custom hand made alternator, and havent heard back from him since. havent gotten an email, and he will not answer my calls. i have left a message, but when i tried to leave another one i got a message saying his voice mail was full. USPS confirmed that he recieved the money order on the 11th, and that was a full week ago that i have waited and not heard anything from him. can anyone help me out here, i dont wanna start pointing any fingers, but a full week when i havent heard from him and dont have an alternator yet he is holding $500 of mine isnt exactly letting me sleep easy at night. anyone else on this forum dealt with him…

So like the title says, im looking to buy bout 50ft. of 1/0 power wire. Which brand should i go with? Have been looking at stinger hpm, knu kol fleks, kicker, welding cable but not sure what size and if its even good for car audio, and shok. Going to be running approx 3.5k watts of power from it.

So I was just about to buy the AudioControl lc2i and I saw that it has "2 speaker-level inputs with 400 watts RMS power handling". I have 2 crescendo bc2000s and going to have 1 crescendo c1100.4. I won't be using them all at full output, but somewhere around 3.2k rms all together. Does that mean it can be hooked up to speakers that are getting up to 400 rms or does it mean that it can only support amps up to 400 rms. I looked at reviews to see if others have used with more power and they were all under 600 rms. I didn't see any other LOCs that support more power. Will the lc2i work? If it is that I can't use this one, are there any other LOCs I can? Thanks. http://www.cr…

ok i have a problem with my voltage. i can't seem to find the problem so i was wonding if anyone could help. I have a 250 amp alt with 2 runs of 0 gauge 3 batteries one is 100ah and the other is 139ah. Plus the blue top under the hood. The amps are a sundown 2500 on 4 12 skars and a sundown 1000 on 2 skar 8s and a old school Rockford 1500 on the highs. But at full tilt I drop to 11.8v and driving 12.2v idk what the problem could be. all grounds are to the frame and i did the big 3 all 0 gauge. all batteries tested fine. If u have any suggestions please let me know. Thanks!

I just noticed the other day that when I hit the nav. button on my 8120 it just goes to a black screen. The rest of the 8120 seems to be working perfectly.... except for the blacked out nav. screen. I know that the Garmin nav. on the 8120 is hard drive based so I'm wondering if the HD has crashed or died..... I tried resetting the unit but still no luck. Anyone else run across or heard of this issue before? I'm calling Kenwood on Monday but just looking for ideas first.

Would 2000 be to much for 2 SA-10's? I was told by Jacob too put them into a 2 cube box, but i dont know if thats too much power.

got a couple of memphis 16-st1000 amps and i was wondering if they can handle a .5 ohm load for burps?? anyone have any knowledge? all info is greatly appreciated. thanks

So my knew 220 anp alternator came in I cant fully test it cause Auto Zones tester only goes up to 100 amps but it's working fine as far as I can tell. Here's my problem my 2002 Taurus Idle stop is set around 900 RPM (no dimming out of gear) holding at the 100 mark on Auto Zones meter but when I put my car in gear the RPM drop tp 550 to 600 only giving me an output of 68 amps so if I'm at a stop light I get slight dimming. I did a eye test and left my interior lights on and the get super bright when I get to about 1400 to 1600 (not exactly sure cause the guage isn't that defined) with absolutly no dimming. Has any one else had this gear engaged problem and can it be solv…

I know there numbers but would like to know,of any personal opinion's which one and why

I've been looking for a cheap amp to power 2 morel tempo 6in coax, and i found a small one, but i came across this CRAZY deal and for the same price, i get more power, plus extra to give my sub in the back more than it gets right now http://www.ugotadeal.com/product_info.php?...uejmadbkkre83j5 and if thats not enough i can always go with http://www.ugotadeal.com/product_info.php?...uejmadbkkre83j5 for a couple bucks more no prob. I just wanna make sure it's worth it because I've never heard of Crunch before yesterday

Is there any difference between kinetic racing batteries and regular kinectic batteries? I'm looking for a trunk battery for my build and was looking at an HC2000, but I found a better price on the KR2712. Which looks to be the same battery but in a red case. I went to kinectic's site to look up the racing line of batteries. But they aren't listed anymore. Which I'm guessing is why the racing line is cheaper since it looks to be discontinued.

I've seen these batteries locally in Houston but can't find much info on them. Looks identical to a kinetic. Cheap rip off? Or just a generic at a lower price?

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.

Hey guys, I have a couple of questions in regard to properly setting the gains for my new SSA Xcon 18. I have a Pioneer AVH P4300DVD head unit with a Rockford T1500.bdCP amplifier, and the Xcon in a custom 6.5 cubes ported box tuned to 33hz. I am using a DMM to set the gains and have read that the amp gains are supposed to be set while all the HU EQ settings are flat (or on 0), the volume on 3/4 the max setting, and a 50hz test tone in the cd player. I am not sure how right that is so I decided to ask. My questions is what is the best way adjust the sub "bass boost" and "output level" settings on the HU? Do I put them on my desired point before adjusting the sub amp gains…

The amp in question is a Linear Power 4.1HVS taken from another forum.. in the highlighted section above, i know there is a flaw in the maths.. can anyone please point it out for me??
