Hey can u do me a favor and list everthing i would need o yeah and im getting Jbl amps and they accept either 8 or 4 guage power cords
I'd go for 2 L7 15's. This is what you would need:
Run 0/1 or 2 gauge power wire from the battery to a distro block. Within 12 inches of the battery, hook up an ANL fuseholder with the approrpiate size fuse (add up the total amps of your 2 amplifiers and get as close to that number as possible without going under). From the distro block, run a 4 gauge wire to the power connection of the one amp, do the same for the other.
Find a bare metal spot somewhere on your chassis as close to the amp as possible. Sand it down first making sure its completely bare metal. Connect 0/1 or 2 gauge ground wire to that spot and into a ground distro block. From the distro block, run a 4 gauge wire to the ground connection on one of the amps, do the same for the others. Try to keep these wires as short as possible.
Does your HU have a subwoofer output? If so, run some RCA's from that output (you can use another preout like the rear if your HU doesnt have a sub or non-fading output) then into the trunk. On each connection, use Y RCA splitters that have one female and 2 male ends. Plug a splitter into each connection, so you now have 4 RCA's total, plug them into their respective amps.
Connect the remote wire to the remote turn on wire from your HU, run it to the trunk. Connect some remote wire to each of the amps remote connections. You can either solder all 3 of these wires together, or get a connector that is specific for 3 wires (i forgot the name of it). Soldering is easiest though, just dont use too much.
The L7 15's are dual 4 ohm, so youre gonna want to wire them in parallel. On one sub, connect the pos to pos and neg to neg, then wire it up to the amps speaker leads. Do the same for the other sub and amp.
Is your car running on a stock alternator? If so, you're definitely gonna want to get a higher output alternator. Go to a local shop and see if they can re-wind it for you, i'd say at least 150 amps. A nice new battery is also a must, check out Optima, they make great products.
I'm pretty sure thats it, someone let me know if I'm leaving something out.
Oh yeah, those kicker 15's are only 1000RMS, while the JBL puts out 1200 (i think it was measured to actually put out close to 1300, not sure though). Be careful with the gains so you dont overpower the subs. It's gonna be harder than normal because you have to tune both of the amps gains to the exact same level. To do this, after you get everything installed, turn the gain completely down. Turn your HU volume up to the loudest you ever plan on listening. In your case, i'd put it a notch or 2 higher than that. Then very slowly turn up the gain on each amp until you hear distortion, the moment you begin to hear the subs distort, turn the gain down a little bit on each amp and you should be good to go. It'll probably be less than 1/2 way up.
good luck
