whatme Posted February 24, 2006 Report Share Posted February 24, 2006 Ok. Im pretty new at audio stuff so excuse my inexperience. I am planning on redoing the entire system and was wondering what amp i should get.Im planning on having (Rockford Fosgate 5.25" high perf. coaxials)x2 as the midrange and (Rockford fosgate Punch 10" 800w/400w(rms) subwoofer)x2. What would be a good amp for this setup?Also i was wondering about the midrange. Im not set at all on the 5.25" coaxials and am completely open for suggestions. I really dont want kick pannels so these would go in place of the stock speakers. Thanks for the help. Link to comment Share on other sites More sharing options...
1997850T5R Posted February 24, 2006 Report Share Posted February 24, 2006 I'm no expert, but i would recommend two amps for that setup, one with a low pass filter and a high pass filter for the seperate speaker systems. Link to comment Share on other sites More sharing options...
NGB Posted February 24, 2006 Report Share Posted February 24, 2006 Two amps would be preferable, unless you're amping the new speakers off the factory amp.In which case you should bee looking for an 800watt RMS mono or 2 channel amp. It depends on the impedance of the subs. Link to comment Share on other sites More sharing options...
whatme Posted February 24, 2006 Author Report Share Posted February 24, 2006 if i was to get two amps, how many watts would i want in each? 400 for the midrange then 1600 for the bass? Link to comment Share on other sites More sharing options...
Ivanfbi Posted February 24, 2006 Report Share Posted February 24, 2006 Bing keeps saying that Infinity Kappa 5.25 speakers are best for stock 850 replacement. As for amp, i would get 2 matching amps rated for different watts. Look into Alpine V12 series, Phoenix Gold Xenon line, Hifonics, JBL, well, just do some research on audio forums. Avoid these: Boss, Kraco, Legacy, Lanzar Vibe series, Profile, Pyle, Pyramid, Rampage, SPL, Volfenhag, Dual, Sony Xplode. Link to comment Share on other sites More sharing options...
whatme Posted February 24, 2006 Author Report Share Posted February 24, 2006 why not just get a 4 channel amp? Does having a multi-channel amp not solve the problem of needing more than one amp? Link to comment Share on other sites More sharing options...
Ivanfbi Posted February 24, 2006 Report Share Posted February 24, 2006 Lets say, front speakers are 75-80 Watts RMS and sub will be 300-350 Watts RMS. If you can find some amp that will do 2x80 +2x300 you can go that way. also can go with 5+ ch amp and use 2 front channels for front and bridge the rest for subs.

whatme Posted February 24, 2006 Author Report Share Posted February 24, 2006 hmm...guessing there isnt an easy way to do it with one normal 4 or 5 channel amp? Link to comment Share on other sites More sharing options...
Gregg Posted February 24, 2006 Report Share Posted February 24, 2006 if only you would pay attention and look at the pinned threads in this forum http://volvospeed.com/vs_forum/index.php?showtopic=5013 Link to comment Share on other sites More sharing options...
whatme Posted February 24, 2006 Author Report Share Posted February 24, 2006 actualy i did read that, and all of the other pinned threads. But it didnt answer the question i was trying to ask. It doesnt really talk about amps except explaining that amps of the same price range from reputable companies will be the same. It doesnt talk at all about what amp should be selected for what type of setup.. Since i will have 1600 watts in subs its a bit different than one 400 watt sub. I wasnt asking if you could use a 4 channel amp to drive both subs and speakers, i was asking if there is an amp that has 2x400 watt rms outputs and yet still outputs that are low enough for midrange, maybe even a suggestion of a brand. Every amp i have looked at has either not enough high wattage out put for the subs or to high of an out put for the midrange. I was following the suggestions in that thread by planning to get a 4 or 5 channel amp, but everyone elses response so far indicates that would be a bad decision. I really know very little about stereo so a guide as sparse as that one still isnt really to helpfull, and thats why i wanted to asked people who were experienced in the area. As much as i try and research it my lack of basic knowledge tends to make everything above my head. Any help would be greatly apreciated, and im sorry for my lack of knowledge about the subject. Thank you Link to comment Share on other sites More sharing options...
Gregg Posted February 24, 2006 Report Share Posted February 24, 2006 if you had read between the lines in Bing's post or done some research of your own, it would be easy to figure out...Get two amps (just like ivanfbi said)...you only need 50-75watts to drive those Rockford coax speakers (so 2x50 or 2x75 amp). For the subs, a 2x250 or 2x300 will be fine.The reason you can't use a single 4-ch amp is because the subs you're looking at are going to be overpowering the coax speakers you picked out (any time you're running two subs, you will almost always require a separate amp for the pair of subs).Really, if you're looking for sound quality, then go with a set of reasonably-priced component speakers, and a single 12" sub. Then you'll be able to use a single 4-ch amp (2ch for the components, and just bridge the other two for the sub). Link to comment Share on other sites More sharing options...
whatme Posted February 26, 2006 Author Report Share Posted February 26, 2006 i guess thats what i get for a long post....another reply without even having read... Link to comment Share on other sites More sharing options...
Ivanfbi Posted February 26, 2006 Report Share Posted February 26, 2006 OK, for subs, I recommend Phoenix Gold X200.4 and bridge 4 channels to 2. And for the mids, get X100.2Phoenix Gold Xenon amps are rated by RMS power, they don't even state max power, and to say truth, max power is really not important. That means that your subs will recieve continuos 400W...well actually about 470W each, and I bet that those subs are rated somewhere 200-400W RMS, and your speakers will recieve 100W (in real life about 130W) all the time, which maybe even overpowering them. Also, don't say that you have 1600W stereo. adding max power rates never works. Link to comment Share on other sites More sharing options...
