hey guys again with some noob questions Tomorrow i am going to start my build be for i get far into it on my old setup i had an extra battery i had the negative on the second battery connected to my main battery since there both in the trunk so my question is was that wrong? should i have the additional battery's grounded to the frame? if i am right about my mistake i am thinking of grounding my additional battery's to the frame. then power from main battery to second then third battery and a fuse from battery 3 to amp? that correct?

Does anyone know much about this amp? I had a hc100 us amp but was kind of dissapointed by the performance of it ,so hope this one aint the same

I'm at my wits end trying to figure this problem. I don't know it's my amp, battery, or alternator. I have one Kicker sub amp and one Alpine 4 channel amp. The problem lies with the 4 channel amp, it keeps turning on and off. It only happens randomly. I have checked all connections and they are tight. I checked all fuses and they are good. I also have relocated the ground for the 4 channel amp but the problem still continues. The gains are not maxed at all on both amps. I have checked the voltages multiple times and there are the results : All measurements are at car idle. Both amps on : 13.79 volts - 13.81 volts Both amps on and AC running : 13.79 volts Both amps on, AC…

Im getting a 18' Fi BL 1000watt Subwoofer and I have no idea what kinda amp to get...Im looking to spend under $250...what kind of specs do i look for in a amp?? ALso i have the choice of getting a 1 ohm or 2ohm subwoofer wtf is that all about i have no clue???HELP!

I installed an Avital Avistart 4400 today and I'm having a simple problem. I am just using the alarm features, so I did not hook up anything for remote start. Upon testing the unit, when I ope the door, it activates and the display on the remote shows door intrusion. I cannot get this to stop even after disarming the system. Do I have to have the remote start hooked up so it will read an ignition cycle and reset the alarm so my LED stops blinking and remote shows normal status? Thanks in advance.

hey guys. i need some input on what kinetic battery to use in the trunk. i have a stock alternator and my setup will be pushing around 2500watts. i plan on using a yellowtop up front. so my question is how many watts should my kinetic in the trunk be? the power cell calculator on the site says i should use (2) 1400watt power cells. which will be costly to me. any cheaper solutions? do i really need that much? input please and thank you.

I just purchased my sundown100.4 for my front stage. I will be running 6.5's in the kicks and two 3 inch full ways in each of my pillars. I will band-pass 3&4 , for example channels 3&4 will have the subsonic filter set at 150 hz, then I will set the Low pass frequency crossover at 4,500Hz for the 6.5's. Channels 1&2 would be set on High Pass and the High Pass Crossover set at 750Hz for my pillars. I will be running tweeters on channels 1&2 also, those will have a high pass crossover set a 5,000hz run in-line. The rest will be active. I was wondering can i use my o scope to set the dials on the 100.4 crossover, as they do…

so i upgraded from a zx750 to a zx1500 and i dont really notice a huge difference from the two im pushing two kicker cvx 12" at two ohms my head unit goes from -15 to 0 to +15 db on the head unit and i dont really see a big difference from the new amp i usly keep the head unit set around + 11 i was thinking if i doubled my amp size i would go from only having my head unit set to around + 4-5 to get the same out of a + 11 db setting on a zx750.1 is it just my electrical thats keeping my system back ? am i missing something i mean my side mirriors viberae the same but i was thinking i would get a huge difference in sound going from 750.1 pushing two CVX's to goin…

There is a JL Audio 500/5 for sale in my local pawn shop for $250. Aesthetically speaking, it's in damn good condition. Has been mounted, but that's really it for scratches and such. I'm not interested in it, nor am I selling it, but figured I'd see if anyone else was interested in having me pick it up for them and them shipping it to them. Doesn't seem like a great price for it, but certainly not a bad one!

Any one know where i can get a new pigtail for my headunit? upon further inspection, it appears it is missing a few wires... thanks chop

I'm looking for some good coaxial speakers. I had a pair of MTX 4 ways and I liked the way they sounded alot, however I can't find them anywhere anymore. What I liked about them were they were built tough and gave me great highs with alot of detail. Who makes tough built coaxial speakers that come in 4 or 5 way 6x9s? I was looking at Pioneer 5 way 6x9s. Are Pioneers any good? I want a good pair of 5 1/4s and 6x9s. I had Kenwoods, but those sucked compared to the MTXs I had.

I have a 2001 Blazer 4 door 4.3L 2WD and i think my alternator is bad. The things i have nticed are when i have the car at idle and i give it gas to about 3000RPM and let it go, the volts according to the gauge cluster go from 14.16 down to 13 volts and then it jumps back to 14.13-16 on idle. Another thing that i have noticed is i have a 1000watt RMS car audio systm and when i have my music up decently loud. My sub cuts out until i lower the volume a bit. The battery i have unde the hood is a brand new optima yellow top. The one with the light grey casing. I also have the big 3 upgrade using 1/0 tsunami oxygen free compotion power wire. My grounds on my amps are good. Ful…

I am thinking of getting a new head unit. I really like double din monitor head units. I have seen the pioneer avics and i really like them but i don't know if i want to spend upwards of 500 on a head unit. Does anyone know of any other quality brands for head units that would have something like what im looking for? It also needs to have 2 sets of rca outputs and 1-2 sets of rca inputs including video.

a friend of mine has a pioneer avic-f90bt and he is running a 300/4 and a 500/1 when he has the balance/fade centered, it cuts out all low and mid frequencies, when he fades it all the way to the front or to the rear, it plays at a normal full range strangest problem i have seen. i have yet to get in there for my self, but i asked him the following, how many sets of RCA are being used : 3 are you sure they are all into "outputs" on the head unit :yes did you try another amp : yes a boston 4 channel same issue have you tried another head unit : no he also stated that pioneer has a few updates on the site, i recommended he reset the head unit, and then downl…

Are the MIDI fuses better than the bigger anl fuses?

so today i went to a car audio shop to get a 2 way alarm system with remote start. when the guy finally finished the system worked fine and then i realized when the car was off and everything locked.. the brake light and the front caution light wont turn off...... does anybody have any idea why this would be.... its almost 11 at night where im at and the guy told me to come back in the morning which means i have to disconnect my batt so it wont die and the re connect it in the morning.... CAN ANYBODY PLEASE HELP WITH THIS TOPIC..... im very frustrated right now..?????? thanks

Hi guys i hope u can answer a question for me. Is there any way to test an amps rms rating other than a bench?? Possibly having it installed in my truck?? Thanks in advanced

I have a Carver 2090mi that I got back in 93 It's gotta be the cleanest and for it's size the most powerful little amp I've ever owned. I used it to run 2 4 ohm 12 inch kicker stilwater designs that I got in 92 and yes they still rock, I want to incorporate it with my new setup and have lost and forgot the specs. I've tried and was unsuccessful in locating them. Maybe someone from the olden days knows.

sorry I double posted idk how to erase it on mobile.

I am planning on buying some XS Power batteries to replace my Deka Intimidators. I have a g34 as a starting battery and 2 g31s in the back as of now, so I guess the first question would be if I need to upgrade them at all. I will be running 2 crescendo 3kwds at .5 ohms each, a MB Quart DSC4125 bridged at 4 ohms, and a MB Quart DSC480 bridged at 8 ohms. I am rebuilding an alternator to give me more idling current, so I think it will end up being around 275 or 260 max. I am going to run an extra run of 2/0 gauge through the truck and my big three is done in 0 gauge. If I were need to upgrade and change my batteries what would be a safe amount to maintain my voltage? I…

Ok I am trying to set my car up as SQ so I am lookin into another Nine.1 and another 2 ch so I can go 3-way active....only one lil problem my car has 100% stock Electrical. I found a few places to get an alt for about $350 for a 200 amp unit, here is the kicker tho.... I was looking at the do it yourself manuals at autozone (Haynes I think) and its telling me I have to pull both axles and pull the K member, then drop the motor 6 inches or so to get it out!!! F*$& that I am a welder and I have access to a water jet. So will adding another alt not of the same make or model cause me any problems. I was just going to get a one wire unit and a longer belt, make some mounti…
