Stereo/Amp Questions
OK so this is my amp. It only drives my sub, a JVC, duel pickup (or whatever you call it when it has 2 cores/magnets and takes 2 inputs). I am re
wiring it all and just have a few questions. 1. ATM i have both the LPF and the HPF on. Is this right? 2. I want to turn it up so should i turn the
little nobs towards 6v or 0.3v. 3. should i run a L & R to both front and rear via RCA or just the left to the front and right to rear (or vice
versa) as they are both going to the same sub? 4. Can you see anything else im doing wrong?

turn the high pass filter off, unless you want to play vocals through the sub and turn to 6v, also what head unit are you running? As that makes a
massive difference having that set right

with that stuff. Its just not being sue about amps

Hi
Its a JVC deck, KD-VD7205. It has preouts (4x L&R, front & rear and sub out) that I was running to the sub amp, the other speakers are running
off the deck.
The amp has 2 bridgeable out connections, one for the front and one for the rear.
So do we run the L&R, front & rear preouts into the amp, we were just using the sub out?
The amp has a switch on the front circuit labelled HPF, on or off
On the rear circuit it has switch labelled LPF, on or off.
Steve

Just some checkerboard vinyl. I have it on my windscreen as well. If you are in sydney i will get my dad (1303steve) to throw up the details of where
he got it. I would love to see your floor if you could chuck some pics up. Checkerboard is becoming the theme of my car lol. Would you happen to be
another ska fan like myself or just a fan of the checkerboard?

OK so i totally didn't even take the effort to read you are from Brisbane. But yeah it is just some checkerboard vinyl that you can find around
easily enough. And the dash on the 1303 has that little pannel removable so we just took it out, vinyled it, then put it back in. I love the look of
it though. Gets some good looks at shows lol. Oh an another checkerboard thing is my speedo which you can see at the link in my signature

It sounds like you have a dual voice coil sub it will have two 4 ohm or two 2 ohm coils in it , the amp is not the right one to run a Dual Voice Coil
sub.You have a 4 channel amp that is designed to run a set of full range speakers from the front on full range or high pass,you cannot use this output
as a low pass for a sub and a set of full range rears or 1 single voice coil 4 ohm sub.
You will need a mono-block sub amp or a large bridgeable two channel depending on the impedance of your sub coils.
If you run a dual voice coil sub off a four channel the way yours is hooked up you will get slight phase variations in the signals coming from the
separate channels,so the two coils are fighting against each other.Also one coil is getting a full range signal and the other a low pass signal,NOT
GOOD FOR YOUR SUB.
