PrimerPlus Posted February 14, 2014 Report Share Posted February 14, 2014 Hello everyone! I am new to the site, also new to car audio. Well I am here looking for advice. Hopefully you guys can help me out so I can get this going. Here is what I currently have. Red Top Optima Battery Deck (Pioneer DEH-6300UB)Front Door speakers (RockFord Prime Full Range 6.5" 4ohm 3-way) 40watts RMS 80watts PeakRear Speakers (Rockford Prime 6x9" 4ohm 3-way) 60watts RMS 120 watts Peak What I am looking to do: I plan on using my Nexus 7 tablet as a headunit that connects up to my Deck (Pioneer DEH-6300UB). Anyways I need to upgrade my sound system. What I have been looking at to power my current speakers AMP Rockford Fosgate PRIME R300-4 300W Prime Series 4-Channel Amplifier http://www.sonicelectronix.com/item_19566_Rockford-Fosgate-PRIME-R300-4.html?utm%C2%BFsource=google&utm%C2%BFmedium=paid%C2%BFsearch&utm%C2%BFcampaign=paid%C2%BFsearch%C2%BFgoogle%C2%BFpla&scid=scplp3601030&gclid=CM6Ju8KUy7wCFUiGfgodaRAA9A What I dont know is what ohm do I wire it too. Also my deck only has 2 RCA outs and that amp is 4channel to power my front speakers and rear speakers. I plan on having 1 sub and 1 more amp to power that sub. So can I use a splitter so I can use a 4channel amp and another amp? Here is the Y splitter http://www.knukonceptz.com/productDetail.cfm?prodID=KARSS1F2M My car is 1998 Mitsubishi Eclipse GSX that came with Infinity Sound System. (stock headunit and amp have been removed). If you think I should replace something or have suggestions let me know. I am totally open to ideas. Thanks again everyone!

CstrokerV Posted February 14, 2014 Report Share Posted February 14, 2014 i would get a new deck with 3 sets of outputs first... my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
PrimerPlus Posted February 14, 2014 Author Report Share Posted February 14, 2014 So are you saying I can't use a Y splitter. keeping my current head unit would save me some cash. Link to comment Share on other sites More sharing options...
CstrokerV Posted February 15, 2014 Report Share Posted February 15, 2014 you can but might not work right.. due t0 every time you split the signal im pretty sure the pre amp voltage splits and you would have to use 4 of them for a 4 channel amp and a sub amp my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
PrimerPlus Posted February 15, 2014 Author Report Share Posted February 15, 2014 Thanks for the reply! I have searched around on the net and seems that this will work to use a Y I just loose the ability to fade front to rear. Also I will only need 2 because I will be using 1 Y for power both Left speakers(front and rear) and 1 Y for both Right Speakers (Front and Rear). That leaves 1 RCA out for the amp that powers the sub. At least I hope my logic is right. If all fails, ill just power rear speakers fron head unit and front speakers from amp. And in the future I can get a better head unit. Any info on my other question for how to wire it up for the correct ohms. Thanks again! Link to comment Share on other sites More sharing options...
CstrokerV Posted February 15, 2014 Report Share Posted February 15, 2014 so you have 2 sets of rca's then yes you will need only 2 but if you only have 1 set then you will need 4 .. ohm wise just hook 1 speaker to each teminal if you want to save money just buy a 2 channel and just power the fronts with an amp and the rears with deck power... my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
