hey everyone i just purchased the following..... pioneer deh-7200sd hu jbl gto 1202d 12" sub and box jbl gto 1004 amp 4 channel jbl gto 938 6x9 parcel shelves tsunami 8awg wiring kit
so i want to connect the 2 6x9 speakers to channel 1 & 2 and then the sub to channel 3 & 4 my question is that the wiring kit i have has only 1 set of rca's so will i need a total of two or three ? here is my my amp (http://www.jbl.com/resources/Brands/jbl/Products/ProductRelatedDocuments/en-US/ OwnersManual/om_gto1004_english.pdf) for the front it has: aux out R&L, input R&L, and for the rear it has input R&L also do i connect rca's like this from hu...... front R&L output on hu to front input on amp .. and from sw output on hu to rear input on amp ? or something else... im not going to start fitting till i know everything .. thanks on any help given to me will be much appreciated
you need a sub that offers you a single 4 ohm coil, or dual 2 ohm coils, since bridged, the amp will only be 4 ohm stable. you'll also want 2 pair of RCA cables (4 channels total) and your head unit should have F/R/S pre-outs (3 pair) of which you'll use the front and sub pre-outs.
If you're using front speakers as well, I would strongly suggest you consider using the 4 channel amp to drive the four cabin speakers (front/rear) and get a second amp (mono sub amp) and exchange the amp wiring kit for a "2 amplifier wiring kit" (you'll need a total of 3 pair of RCA cables) to run the sub on it's own amp. This would be ideal, else your rear speakers will overpower the fronts and completely destroy any sort of soundstage.
PS, if you go the route of a separate mono amp for the sub, get a dual 4 ohm, or single 2 ohm coil sub, so you can go 2 ohms @ the amp and get more power.
ok right for now i will keep it like this till i got some money lol, here are sub specs 12" 1200W peak subwoofer Dual Voice coil design (dual 2-ohm, pre-wired as a 4-ohm sub) Power Handling, RMS: 300 Watts Power Handling, Peak: 1200 Watts Frequency Response (±3dB): 28Hz - 450Hz Sensitivity: 93dB Mounting Depth: 5-1/16" Cut-Out Diameter: 11-3/16" ok so if i put 1 pair of rca from HU (front) and 1 pair from HU (SW) where do they go to because on amp it only has rear and front input. do i put front HU to front amp and SW HU to rear on amp ? even though the speakers will be in rear shelf, and do i disconnect the rear standard speakers ? for total of 4 speakers thankyou very much i really appreciate
>Dual Voice coil design (dual 2-ohm, pre-wired as a 4-ohm sub) This. Ideal for a bridged amp like you have. Run it @ 4 ohms. If you go separate amp, look at the Audioque AQ1200D. It's $249 shipped from their own website, it's 1200WRMS @ 1 ohm (which your sub can be wired for) or 300 watts RMS @ 4 ohms (your RMS handling for one sub) You can even add a second dual 2 ohm sub to get a 2 ohm load on the amp for 300 watts per sub.
>Power Handling, RMS: 300 Watts more useful to know. this is a thermal measure of how much power the sub can take continuously without damage to the coils from heat.
head unit front channel RCA -> amp front channels RCA inputs -> 6x9 speakers
head unit SW out -> amp rear channel inputs -> bridged rear amp channels -> subwoofer (right pos, left neg speaker wires, or whatever it specifies for the bridged mode output from teh amp.)
This is what you want.
Later when you have a bit more to spend, you will want to buy something like that AQ1200D, a decent set of front speakers, and a power distribution block and a bit more power/ground wire, at which time your setup will go like this:
head unit front RCAs -> front amp channels -> front speakers head unit rear RCAs -> amp rear channels (stereo) -> 6x9s head unit sub RCAs -> sub amp -> subwoofer
This will be a terrific little setup. clean, clear, and loud enough for daily use.
man youre great you have helped me alot i couldnt find any info like this on web i am deffo going to do that after i pay off loan for car lol thanks alot
no harm in doing things in steps. you're better off doing step by step for quality parts as you can afford the work, than trying to do it all at once on a next-to-nothing budget and cheaping out on the gear in the process.
You'll be much happier with the end result, and appreciate it in the end for the wait it took to accomplish it.
