Hi everyone im going to be running a kicker component set for my front stage and in my back seat i will have selenium super tweeters the component set is 4 ohms, but the super tweeters are 8 ohms, the component set is 100rms per pair (driver and tweeter) and the super tweeters are 100rms each. i plan to buy a sundown 100.4 now for the speaker system. is it ok to run everything per channel? what ohm load would everything be? i assume 4ohm and is that ok for the supertweeters? this all sounded good in my head but now physically its lookin a mess lol... please dont judge my decision to get supertweeters, i know i will enjoy them.. this would be my first build with supert…

Like the title says im trying to wire up my components. They are Infinity Perfect 6.1, and im trying to use a kicker kx 250.2 amp. I know I have to bridge the amp to get 4 ohms but every time I wire it up the amp shuts off at high volume for a few sec ds and then tries to kick back on. Some info: 0ga run from the battery to a distribution block From distribution block 4ga to Hifonics 1208 Brutis, 8ga to Kicker kx 250.2 Same size wire for ground to another distribution block and 0ga to frame 200amp alt. with big 3 done SO my question how do I wire this up so I know im doing it right, and what could be making the amp shut off?

Most audio equipment dies for one simple reason. Most people push their equipment beyond its limits. Whether it is the amplifier, subwoofer or full range speakers, clipping is the number one cause of failure. To prevent clipping, use this tutorial. To figure out what voltage you should set the gains to, multiply the RMS power of the amplifiers output by the impedance of the speaker, then find the square root of that number. If you are using an amplifier that has an RMS rating of more than your speaker(s) can handle/rated for, then use the RMS rating of the speaker (instead of the RMS of the amplifier) to determine the voltage to set your amp to. This is also referred to a…

"A second battery is never a good idea as it's an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off."

how would an audiopipe ap1500.1d preform at .5 ohm. with 14.2 v roughly.

I have two giant bulldozer batteries in my barn, hold charge fine. All they say on them is Deka 8C12, 90 min, and extreme deep cycle. They are open cell with acid in them so that's why I'm worried. Would they work as secondary batteries in the back?

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'm thinking about purchasing an Fi bl 15 or 12, and was wondering of anybody knows anything about the hifonics Brutus 1700, is it a good amp?

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!

I was checking out this amp. I remember hearing nothing but good things about their stuff years ago, nothing recently. but I hadnt heard of SSA, sundown, Fi, or... either seen it usually for 260 and up, ikesound has it for 199. Ive seen ratings listed anywhere from 990-1150 watts RMS into 1 ohm. their website as a link to there amps but is loading a blank page for me right now, so I also cant find out if it has a SSF? they any good? put out true ratings? underrated?

Currently on my HU there are a lot of options for bass and sub settings. I currently have the bass setting to zero and the sub settings at -20 (lowest it can go) and on my amp I have set my gain using a DMM and reading the "how to set your amp gain" post. Now I was just curious if by having the subwoofer to -20, and having my eq for anything below 50hz set to zero or lower (on my hu) is hurting the performance at all. Currently, the gain on the woofer is about 70% of the way up and its not clipping. Do I set the sub (lets just say) at 0 and same with the built in eq for anything below 50hz? Will this improve anything? And yes I would re set the gain on my amp. EDIT: I for…

What is the best way to decide on a head unit? My budget is no more than $250. I want something that looks clean, functions well, and sounds good too. Does anyone have any experience with the Alpine iDA-X303?

Hey guys, Just wondering if you could give me some insight on this. When I start to play a new song the front speakers start playing about half a second before the rear ones... The front ones are on an amp, the rear ones are going into the HU... any idea on this?

My buddy wants a cheap system installed in his car. He already has a deck and speakers, just wants a little amp and a little bit of bass. His HU in an intro line Pioneer, bout a year old. It doesn't have a seperate sub out, but only has one pair of outputs. I know he wont have subwoofer control, but could you hook up the one pair of line outs (front) to the sub amp? I don't really see any reason why not, I've just never had to think about it before. Always had 3 sets of outputs. I know its probably a stupid question, but any help would be appreciated. Thanks

Why is it that my headunit nearly has to be turned up all the way for my subs to get extremely loud I have an aq 2200 with 1/0 ran and a second battery and the big three done my headunit is kenwood not sure on model number my subs are 2 audiopipes 15" an are rated 1000rms my headunit goes up to vol 35 and 1-28 are barely pushing then when I hit about 33 it's loud then when I hit 34 there is a huge difference in bass any help thanks

I have a Kenwood x793 HU. I love the features on it. I use a USB 16gig thumb drive 95% of the time. I do compete. I am currently at around 146-147 db. The problem is the faceplate shuts off at high volume. This poses a problem as you can't turn the volume down or anything when it goes off. If I press in the faceplate it will not shut off. My question is has anyone ever had this issue and if so how did you fix it? I thought about soldering jumper wires from the faceplate to the HU. I never take the faceplate off. I'm not sure this would work or not. Thanks

I have a 2005 4runner Limited with the JBL package. I am about to install my headunit and have already gotten my wiring harness and dash kit, but need to know if there is anything else specific I will need. Seen a few modules that are said to be needed to bypass items in the 4Runner. Not really sure what it meant or if needed. Anyone who has done an install on a 4th Gen 4runner (03-09) please help. Thank you.

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…

anyone know of a place that can fix an internal amp on a HU for less than 120 bux.. the place here says 40bux but there labor charge is 80 bux off top <_< .... i talked to david from RE a while ago about it and he said he had a friend that could do it for like 70 + shipp, but he hasn't been on aim lately..

Well, i dont have a problem but my dad and brother do. They are trying to hook up a new HU and it wont power up i guess. He said that after it not working when wired through the wiring harness, he hooked it up to a battery to see. Still wont power on, but he only hooked up like 3 wires... 12volt accessory, 12volt battery, and illumination. He only had those 3 wires hooked up so he could just test the radio. Do you need to connect all of them to get the radio to go on??

How do most HUs hold up under high voltage, say 16V?

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 …

would you guys recommend- 1. running power from battery to the cdplayer instead of using the factory harness? 2. grounding to the fire wall or use the factory harness? deck is the clarion mentioned in my build log (the cheap one that can do active)

Ok i'll start with the part, its broken, i don't know the proper name for it or where to find a replacement, clue me in. http://i2.photobucket.com/albums/y50/vladd...-10-06_1852.jpg I know its hard to tell but basically is an 8pin ribbon connector, a couple of the wires are broken, i could solder them if i had superman vision and nerves of steel, but i don't now for anyone else that may be having this problem...the rear screen on my pioneer 960 went out, thats it, i got pissed, figured what the hell, take it apart and fix it mr mullins, or make a nice paperweight

Hi guys. As the topic states. below is what I have considdered so far pls give advice .. feel free to add and give a reason. preffer not to get processor just yet. system will be used for 2-way active. eclipse 7200 MK II (this is what i wanted to get but now people say its not all that) Price around s$1050 alpine 9887 around $800 singapore dollar clarion D2 (price not sure and the ugliest of the bunch) Pioneer DEX-P90RS (looks promising but way over budget and no-one here have it, so that i can audit it. s$1500)
