They are clearly labeled "input" and "output"..so its impossible to screw it up...btw this aint my first time doing this.

So i ordered a HiFonics Txi 1008D but the site accidentally sent me a HiFonics Bxi 1208D instead...at first i thought it was a great deal since it's an upgrade. So i wired everything up and then i turn on the radio and i hear nothing from the subs. I spend two hours trying to trouble shoot the problem and i still couldn't get the amp to make any noise. I then called the site up and i explained everything and i asked for a refund, but the guy explained to me that the amp needs a mono signal from the RCA's to be able to play music. He said to use a Y splitter on one of the RCA outputs and plug that into the amp. So i did as he said and the amp still wont play any music, i tried putting the splitter on the black and white wires of the RCA. I've tried two different RCA cables thinking that one cable might be bad but that didn't solve anything. I checked and re-checked all my ground and power wires and my fuses, and i tried different sub woofer Ohm loads and still no sound. So now im thinking they knew that it was a defective amp and they wanted to get rid of it so they sent it to me thinking that i wouldn't ask any questions...ITS PISSING ME OFF! Any help would be appreciated, especially in the RCA/mono department...the manual makes no sense to me and it's very confusing so any clarifications is also welcome. Here is the manual if anyone wants to take a looksee: http://www.maxxsonics.net/manuals/hifonics...er%20Manual.pdf I did exactly what is described in that dashed box:

The only way you are gonna fit 4 15's in the back of a cherokee is if you take the box all the way to the top of the ceiling and make it a little more than a foot deep, that will give you ~10 cubic feet. The jeep measures: from spare tire to the wheel well it measures 3.25', from floor to ceiling it measures 3', and from the top of the back seat to the tailgate you have 2 feet to play with. If you build the box right and you dont tune it too low then you could hit 145's with 4 15's at 250rms each, if your jeep came with the 136 amp alternator then you wont need a bigger one. make the box 39" wide, 36" high, 15" deep with 3/4 mdf and you will net 10.10 cubic feet of space, then that will give you about 9" of space behind the box for your batteries, amp, and whatever else you wanna put there. and yes i also have a cherokee
