i need quick help..im installing my aftermarket HU and need to hook up the antenna turn on but i dont see the light green or black w red stripe,is there an alternative wire i can use. also from reading stuff it has to be hooked up to hear sound

[hellion240sx]

I know you don't think it's a good idea. What if i did seal it? would it work better. I Would just like to have the extra space without having to take out boxes and what not. I was thinking about like some undercoating like you would a cars underside along the wall. Maybe fiberglass or the birchwood? I'm just playing around with ideas. just trying to find a box to fit the back is going to be tougher, I don't remember it being that big of a space... I'll check tomorrow.

thanks again for your input.

well I was looking at some other subs now. MAybe to shoe horn a box in there. But at that size i only have 1.6 cu ft of room. which I can make a sealed box for two subs that need .83 cu ft each... is that correct?

[GSXRJJordan]

Any modern 10" woofer will be very happy in .75ft^3 of space. You could build a very nice vented 10" box like I did (I think mine was 1.6ft^3 with a HUGE port) for a single woofer, or go dual woofers in a sealed box. I'm currently using AVI SL250's in my truck (transplanted from my FD). Very tight response, still loud, doesn't need a ton of power.

Also, I build all my boxes for sports cars (where weight is a concern) out of 1/2" birch that I then pour a little fiberglass resin into to seal it. Stays very rigid (as rigid as MDF) and is almost half the weight of 3/4" MDF. That also gives you a little more internal volume.

Don't forget to poly-fill your box if you go sealed.

im having a bit of trouble with my install well not so much that but the deck will not hold memory,is there any other place i can try?

[GSXRJJordan]

If your deck is not holding memory, your constant +12V wire is not hooked up (or you have a REALLY horrible grounding location).

Check your fuses first, then pull the deck and check for power on the red wire going into the head unit.

my ground is good its hooked up to the shifter nut cover,how do i check to see if its getting power to the wire oh wait it has to be working because in order for the deck to even turn on both 12v have to be hooked up

That's where you're wrong, just about every deck turns on with the ignition-switched +12V wire, just uses the constant to store memory.

would it be crazy to have a ported and a sealed box next to each other???

the constant is the red w black stripe 12v battery correct and thats what i have hooked up but its not keeping memory or am i wrong and the blue is the constant

Would do much more harm than good. When you have two drivers with different frequency responses (like one ported 10 and one sealed 10) you would get constructive and destructive interference, like you sometimes get with subs and mids that have their crossovers not set correctly. Sounds like crap.

Test to make sure there's voltage on that wire with a multimeter or test light, if all your fuses in the driver's side kick panel are good (like I said in my first response).

[norcalslider]

yup thought so,mine isnt holding memory

Wow thanks man! okay well two tens in a sealed box it is...Or would you recommend a bass tube? I have never heard one. ANd I am very skeptical about them.

I figured I'd best just bring this thread back from the dead instead of starting a new one so:

I'm pretty set on the nice components up front 10" sub in the back run by one 4channel amp idea that seems to be the status quo in this thread, my question is this: I've been doing probably way too much reading around the net on rear fill and it seems to be a universal truth that when done right it is a huge improvement to a system, broader stage stronger mids and lows improved imaging blah blah blah. Most of those guides suggest things far beyond the budget system I'm planning wiring into and out of amps and processors in different ways to (L-R) etc. Any good ways to get the desired effects while still retaining a minimalist system? I.E. can I just wire my deck to the rears do such and such with the equalizer and sit back and listen to the improvements? My main reason for wanting to retain the rears is like so many I have a loud car and those extra speakers will go a long way overcoming my exhaust without putting heavy sound deadening all over my sweet race car

Skip rear fill. Spend that money on a better front stage and/or sound deadening.

damn dude two dc l4s? Are you trying to make your car rattle apart? haha nice setuo though

That's wat I want to do but I need a new box design for these dc and tune it to lower hz

Any car audio wizs out here that can help me with my problem, I think the the promblem is called an "alternator whine" When i have my stereo turned off i dont hear it when im accelerating or anything but when I have my stereo on and turned down a little I hear a whine as soon as I accelerate or give it any throttle. Could it be due to poor rvc wires? My setup is a 5 channel amp hooked to all my speakers and a 10 inch jl sub.

[DoobieS13]

hey i got a question for you audio dudes. all i want is to plug my phone in and listen to Pandora radio. i don't have a radio at all in my car due to my gauge panel. do they make something with a aux port that i can hook up to my amp that i have and run through my speakers...if not can i rig something up? thanks

[joemon]

@jonathong
Check ur grounds
Or most likely its ur rca cable is to close to it power wire
Run ur power line on the opposite side of the car
Or wrap ur rca wires in heat shrink or tape

You could have several issues:

Make sure your signal wires(RCA cables) are ran down the opposite side of the car from the power wire and remote turn-on.
Any component in the audio system(head unit, amplifier, processor) might have an improper ground. Make sure all grounds have less the 1ohm of resistance.
You may just have cheap equipment that is prone to ground loop issues.

Start with these then get back to me if you are still having issues

You can simply just get an 1/8" to RCA cable and plug it into your amplifier to try it out. However, you will most likely need a preamp to get the proper preamp voltage into the amplifier.

yea that's what i was going to use but i didn't know if it would sound good if i wanted to crank it up. what could i use as a pre amp?

[joemon]

Lol Sry I did beat u to it.
But u r the certify one to listen too haha

But doobies13 without a headunit there's not much u can do that I kno of.

But the cable to ur amp from ur phone, ipod, mp3 player, ect. Will be ur only choice that I see.
Just don't turn ur phone volume all the way up leave it 95% volume up

[azngangster2002]

subwoofer go bangbang

[HIGHFIVEBETA]

What set of speakers would you all recommend for a setup of only 2 fronts? I removed my rears and have no subs either. Plane jane basic 2 fronts setup. So I want a set of good bumping speakers with good sound quality. Please help!
