Suggestions for System in Classic Car

Knukonceptz is great, affordable wire. I've always used them and it is quality stuff.

 

it looks as if that "sub in" can be summed from only having one input.

 

I forgot to mention it before but you are going to need two sets of RCAs. On the back of the headunit you have 3 sets (front, rear, sub) run a set of RCAs from the "rear" pre-out to the "AMP1" input on the amp. Then rn the other set from the "sub" pre-out on the head unit to the "sub" input on the amp.

As for wiring, on the 6x9s yes just wire them like you said, each respected polarity to the respective terminal. For the sub you are going to first wire the coils in parallel then wire it to the amp (i'll attach a pic). I'm glad you're asking questions, no point in acting like you know stuff to only ruin great equipment and we don't mind at helping at all.

 

And I think Pedro meant you could get away with just running a single set of RCAs. You would just wire one end (say the red side) into the "rear" (red) output on the HU and the other (white side) into the "sub" output on the HU, then keep it true to the amp (red to red on the AMP1 input and white to white on the SUB input). If you do it that way you will lose control of rear fade from left to right. Just an option.

 

no. his amp can take just one input if it had to. there is a button on the amp that lets you select one input or two inputs. in case your head unit one had one out put.

but if his head has front and sub he's ok. worst case scenario, if his amp wasn't able to sum the sub ch from the front input i would have told him to use a Y splitter to the sub in.

the button that says sub input should be set to amp 1 input if you dont have another set of rca's to plug into the sub in.

 

you can use the other set you arent using as the ones for the sub input.

 

yup. as long as its an input. the internal xover will turn it into a sub OUT.

your good to go.

i'd like to see how this turns out. pics when its installed please

 

Its kinda difficult to say which way to aim the sub but generally towards the rear is how you want it. The thought is it gives the sound waves more area to build and then they reflect back through the space louder than when they left. Of course rattle can kill sound and no car is perfect. I will say though that if you should build the box where there is enough room (several inches at least) above and/or beside the box for sound waves to travel back through.

For the remote you can just run a little jumper cable from the remote on the amp to the power terminal on the amp. I had a friend who did this and it worked fine for him. If I'm wrong guys let me know cause I don't want somebody to fry their amp trying this.

 

your wrong. the amp will stay on continuously with no way to power it off.

if your amp doesnt have a remote out you can wire a turn on lead to a switch and power the amp on that way. i would how ever use a power source that only has power when the key is on, so if you forget to turn it off it will power itself down.

 

looks great!. you may want to think about covering the rear of the 6x9's with something to seal them up.

the air pressure from the sub can and will make them over excurt (*sp).
