I have a question. I have 4 12'' subs, each one is 500 watts max, and 250 RMS. They are all 4 ohms. I wanted to get a 4 chanel amp if its easyer. The amp I want to get is 1600 watts. Can anyone tell me if this amp on this link is capable of getting good bass out of my subs. P.S- the subs are lightning audio. Thx Replies (28) 2fastxd on 08/16/2004 01:43:13 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4950&item=5714114790&rd=1 this is the site, please tell me if I should by this uochronos on 08/16/2004 02:06:27 that amp would not net you good bass it is only cabale of maybe 150-200watts per channel and i doubt that is in 4 ohms. in general this is a bargin basment amp and you really go get what you pay for... all 4 subs wired together right well net a 1 ohm or a 4 ohm load. so a good 2 channel amp or a good 1 channel amp is what you should be looking into. what is your price range and i well look up some amps in that range for you... off the top of my head a JBL power valve 1200.1 would work well here and they run under 300$ there are several on ebay for 240$ and this is a really great amp that well give you what you want from these subs. also the jbl 600.1 would work and is around 50-60$ less on ebay then the 1200.1 a 4 channel amp or a 2 channel amp big enough to power your subs is going to suck alot of power from your alternator and require upgrades of battery, alternaot, and wiring to them. this well cost around 400$-600$ just to upgrade power system to handle a 2 or 4 channel amp that big. a 1 channel amp pulls less current and if gain is kept at a reasonable level and not cranked all the time well probaly be ok.. although even with a 1 channel amp at 1000+watts upgrading electricals may be required. it may be wiser to get a 600watt-800watt amp that well pull alot less juice from the electricals and barely noticble in how much volume you lose. just to outline it bargine basement amps are what you pay for them almost 95% of the time. not as good internal parts and alot of fudging on the spec sheets to get better looking specs. and if you run over 800watts of amp power expect to be upgrading some of your electricals which can get real spendy real fast. ok i hope i have helped you out. please let us know your price range and we can throw in some more good amps in your range. Chronos 2fastxd on 08/16/2004 02:16:59 Thx my price range would probly be around the max of $150, Im a nub so how would i wire the 4 subs. Is there any way I can get a digram. And if any of of the amps you show me what kind of install kits do I need. Thx P.S. do you think 4 of the subs I told u will get good base. Thx 2fastxd on 08/16/2004 02:18:08 i jus bought another cd deck and its has a sub out, and dual rca hook ups 2fastxd on 08/16/2004 02:46:22 would this amp be good, if not whate else http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=18797&item=5715173860&rd=1 uochronos on 08/16/2004 02:53:35 boss is another low end amp company... let me take a look around and find you a couple amps in the 100-150range.... the JBL 600.1 is one that is right around that range and is one ohm stable.. that last one you showed me is only 2 ohm stable... you either need a 1 channel amp thats 1 ohm stable or a 2 channel amp. every sub you add to your set up only adds 3db of volume. lets say 1 of these subs puts out 120db at max volume adding 3 more only raises that 9db not a huge raise in volume... personaly i would go with 2 of them and sell the other 2 and get a nicer amp then you can afford with the 150limit.... that would probaly net as good of results... and no strain on electrical system thats my worry with this system you have planed over 600watts rms and you start getting into the danger zone of need expensive el;ectrical upgrades as i mentioned before alternaotr, battery, wires. etc. 2fastxd on 08/16/2004 03:09:29 theres no way i can get 2 2chanel amps, and hook all 4 up. It will put strin on my battery thx uochronos on 08/16/2004 03:15:08 uo can get 1 two channel amp and hook all 4 up.... the problem is it well not just put a strain on the batter it well strain the alternator if you run a 1000watts worth of amp. and well make your car stall or not start and eventualy the strain well kill your alternator and you well have to buy a new one. where as running just 2 subs at 500watts well not starin the alternator most likly and well hardly lose any volume. over 120db you cant differentiate much volume. and 2 of these subs well pound quite hard... my last set up was a 500watt set up with 2 10" subs i could be heard over a block away when it was cranked up/. 2fastxd on 08/16/2004 03:19:54 so your saying that 4 subs wont be much different then 2subs uochronos on 08/16/2004 03:25:58 the differnce between 2 and 4 subs is 6db of volume. which at the volume we are talking is not a huge differnnce... i well be happy to guide you threw all the upgrades needed to run 1000watt system. but the stock electrical system in a car cant handle that kind of wattage without upgrades. i'm running 2 amplifiers that are pushing around 2000watts but it cost me 700$ to upgrade my car enough to get it to work. it is all your call. but we can help desing a killer system with just 2 subs. and if you sell the other 2 you can get a nice amp that well really make them pound. for instance you well lose 6db by only using 2 of the subs but if you use a ported bnox you well gain +6db so it well be as loud as if you had 4 subs in sealed boxes..... really there are lots of options here but it sound to me that if you want to keep this under 150$ yo wont want to spend the 300$-500$ to upgrade the electricals. please if you dont understand anypart of this ask i well be glad to explaim. Chronos 2fastxd on 08/16/2004 03:36:53 ok i dont understand much, about a week ago , i went to best buy and they had a package sale, 2 12'' 600watt subs , 1 pioneer 760watt 2ch amp and a box. I said , what if i get 2 of these deals . That will be 4 12'' subs ex. they said getting one package would be good but getting 2 will be twice the bass. I was gonna buy it. But anyways they were gonna install 2 760watt pioneer amps in my car and they didnt even mention about the altenator or any of that. what do u think about that. 2fastxd on 08/16/2004 03:37:56 but i didnt get it cause lack of $ uochronos on 08/16/2004 03:41:38 guys at best buy, circuit sityt, etc are there to sell you stuff that is there job... any guy who goes threw high school can sale car audio doesnt haev to know anything. the installers there are usualy new as well and know little. maybe one older guy. places that do just car audio are a step up but in general they dont know or if they do know dont tell you so you well buy more... and no you well not get twice the volume from twice the subs. this is something many a guy at best buy has told me infact the best buy here in portland oregon i wont even shiop at because they did a simialr deal to a friend of mine and then installed it wrong to boot. have you already bought these subs and amps??? the one reason this forum is nice is we arent trying to sale you anything so we have no reason but to state the facts here... and not to worry all of us where new to this at once. and i know how it can get flustrating. uochronos on 08/16/2004 03:42:11 ahh your second post gave my awnser... do you haev the 4 lighting audio subs already? 2fastxd on 08/16/2004 03:45:11 yea uochronos on 08/16/2004 03:47:37 ok i'm going to sort of recap on what i know and see if i got the right idea on what you want... your looking for an SPL(sound preasure level in other words loud and in your face) system you have 4 250watt RMS lighting audio subs you dont want to upgrade the alternator and what not because of cost you currently wish to spend less then 150$ on an amp and amp install kit and have no box for the subs is this all accurate? uochronos on 08/16/2004 03:48:35 this post is getting really long if you wish we can discuss this over a IM system AIM oebchronos yahoo uochronos or ICQ 16919163 or we can continue here. 2fastxd on 08/16/2004 03:49:11 yes good staying wit me lol, complicated 2fastxd on 08/16/2004 03:53:03 do have msn messenger, if not wut is icq uochronos on 08/16/2004 03:54:53 ok sounds to me for you to get what you want the best option with the subs you already have is saling 2 of them. then either build or get a ported box built for these subs. then use the extra money you got from saling the 2 subs to get a good mono amp that puts out 500watts at 2 ohms... as for the box we can either walk you threw getting one built or you can pay to have one built... you can build one for under 50$ and having one built well cost from 100-300$ mattering... the only other thing you well need is if you do go ported is a Sub SOnic filter which we can show you where to buy one for 30$ that just plugs in. this in my opinion is your best bet for a good system with the subs you have and the money you want to spend... and it should sound pretty good and get quite loud. uochronos on 08/16/2004 03:57:15 evidently i do have an MSN account did nt know that lol.... i assume my SN on it is my email which is uo_chronos@hotmail.com 2fastxd on 08/16/2004 03:59:32 damn, i dont know anyone willing to buy my subs uochronos on 08/16/2004 04:01:52 even if you cant sale them right awayn its alot easier to find a 400-600watt amp for 150$ then it is to find a 1000-1200watt amp for that.... also you can always sale them on ebay... i have sold many piece of equipment on there. uochronos on 08/16/2004 04:24:47 http://www.thezeb.com/detail.aspx?ID=6503 http://www.thezeb.com/detail.aspx?ID=3514 here are 2 amps that well work for 2 of the subs swez on 08/16/2004 10:24:35 Doing a fine job here guys. This is not rocket science stuff, but it does take some skilled hands and good planning to devise a low budget, yet great sounding bass system. I agree w/ Chronos on using 2 subs, keep the others for spares or sell as you can. Then use a modest Class D sub amp in a range of 500-600 watts RMS. (that's 1000-1200 peak watts) This type of amp will pull less than 50A of current, stable at 2 ohms and a very good match to your subs. Plenty of SPL available here w/ just 2 x 12's, especially if you go for a ported design. To keep the price down, look for factory refurbs or used amps off ebay. Kicker, JBL, HiFonics, Orion and Audiobahn all offer Class D amps in this power range. The catch is getting them at the price mentioned. Swez soul_karver on 08/16/2004 13:18:48 that profile seems like it would be a good cheaper amp... otherwise i would also recommend a jbl power valve 600.1. all you have to do is find a box that fits 2 12" subs and is designed according to the specs of your subs (look at the recommended volume of chamber per sub and the recommended diameter and length of port per sub) and make sure it will fit in your trunk. then wire the subs to the inside box terminal and from the outside box terminal to the amp speaker outputs (left speaker + and - to the left + and - on the amp & right speaker + and - to the right + and - on the amp... or parallel wire them if the amp only has one + and one -) (any cheap 12-14 guage speaker wire will do). For wiring up the amp, you will need a 4 guage power wire that will run from your battery to your amp, a 4 guage ground wire that will run from your amp to the metal body of your car, any rca cable that will run from the back of your aftermarket HU to your amp, and any plain ~18 guage wire that will run from the back of your HU to the remote turn-on terminal on your amp. You can buy wire/wiring kits at fleet farm, wal mart, target, radio shack, etc. or if want to buy a kit online, this kit has everything you need except a remote turn-on wire (for some reason): http://www.knukonceptz.com/productDetail.cfm?prodID=KOLAK4 Hope this helps. ~SK swez on 08/16/2004 18:06:13 Ya know, a JBL BP-600.1 would run 3 subs if these are 4 ohm single coil version. Tha's 200 RMS + per sub in full parallel and a 1.3 ohm load. That amp will only pull ~50A when you crank it up. Put you in the high 130's dB range too. I've seen the 600.1 being sold at ebay for a shade over $150.00. They are getting harder to find as the new JBL amps are being rolled out and are much more expensive. HiFonics would work too, as these are 1 ohm stavle as well. If you really have your heart set on using all 4 subs, a solid 2 channel will power 2 subs per channel in 2 channel mode. In that power range, 2 channel amps tend to be more expensive though. More circuitry in them as compared to a MONO amp. They also tend to pull more current than Class D or Class T amps. Anyone got a line on Avionixx 2 channel or Class T amps in the 600 RMS range? These amps are Class T technology, very efficient on power usage VS output and it seems to me, they are well priced too. Anybody got a handle on Avionixx amps? Swez 2fastxd on 08/17/2004 03:17:17 THx to everyone for help Copyright ClubKnowledge 2009 * All Rights Reserved |
