Help Audio System!

[GoodMike]

Ok, so i wanted to be thumping in my explorer...so i bought myself a boss amp, a audiobahn sub, and a q logic box. my sub box and sub will arrive today and tomorrow. I have a 97 explorer. We used my friends sub and box and we wired that to my car just to see if we could wire it correctly. now, everything is stock, i have the 6 disc changer in the center console. everything wired fine, but my amp has the high pass, and we ran speaker wire from the stock Head unit to the amp. we had problems with that. i was hoping that i would be able to just use the back speakers, but of coarse the car is wired by left and right. so, we took one positive and one negative from both sides and hooked that up to the amp. the sub does beat...but it is very quiet, and when i turn the music up and down...the sub does nothing different. what did i do wrong??? PLEASE HELP! i just spent 300 dollars...and its not loud at all! very dissappointing...

hey man. Hook up left and right rear speaker leads to speaker level inputs on amp. i assume you need to use both sets of leads. Read the amp manual to confirm this. Should be a simple fix. Then your subs should play. I have no expirience with using speaker level inputs so i could be wrong. Aftermarket HU's are so much easier.

thats the problem..there was no left back and right back...it was just full left side front and back on the same wires. same with the right side.

i had that problem too in my 2000 sport, i just gave up cause the speakers in it sound amazing for stock speakers, i still have the amp but i think im going to try to just wire it up to a subwoofer, but im not sure how to do it from a stock cdplayer, i tried hooking up my pioneer headunit but apparetnly if you have rear radio controls it wont work at least i couldnt get it too, if anyone knows what to do to get it working it would greatly appreciated

ok Good mike......i hope i can explain this good...on your amp you have the HI-Level plug you are using correct?...not the RCAs but a block that has four or five wires comming off of it that plug into the amp... You only have to pull a signal from one side but if the bas is only on the right and you have pulled your signal from the left you wont hear it....

A Signal Pulled From Left and Right -
You have to run wires from BOTH the LEFT and Right +s and -s...4 wires in all....look at your Amp manual and see which colors ar the left+, left-, right+, and right-....hook them up accordingly.....

The possible 5th wire is another ground you can tie into your ground on your amp or you dont have to use it at all

the reason its not working now is because the - is not a signal put out by the Headunit but the + signal returning to your unit...that is where Resistance(ohms) come into play...if the ristance is too low then the signal returning to the unit will be too strong and burn something up...too high of a resistance will cause the speaker to be lower in volume than the recommended resistance.

Good Luck and hopefully I'm right

hey, thanks for the help guys, i just went and dropped 200 dollars on a new deck and they installed everything for free...IT IS AWESOME! thanks again.

well, my sub came today, and i mounted it in a q-logic QB-110.3 box. the sub i got is an audiobahn alum 10 Q. i am running it off of a boss amp rated for 700 watts. so, when i was running my buddies box and sub..it was extremely loud, he has a alpine type S sub and it is in a huge box that he built. my sub and box isnt even half of the sound his put out. why? is my sub not as good? everything else is the exact same....please let me know.

how do you have the sub wired as it's a dual 6 ohm subwoofer? That and since he has a "huge homemade box" the specs could be better for his sub, or it could be a ported box which = more efficiency/output over the prefab sealed.

 

[GoodMike]

when i first got the sub, i didnt see it said 6 ohms...i noticed that last night. frick. is there a way to wire 6 ohms so it is 2?

 

[davesexplorer]

nope, you can parallel wire for 3 ohms at its lowest impedance.

Anyone know what to do if you have rear radio controls? in the wire harness box it says my headunit wont work if i have rear radio controls? anyone else have this problem?

moore-start a thread of your own to get more answers but your head unit will work, the rear controls will not
