99 dollar 800W Amp w/2 10 inch subs at pep boys

[Wichitagreg]

Sounds good, but I have a problem.

The amp takes both speaker level and low level inputs, and I'm using the speaker level inputs.

I replaced the stock premium speakers with Pioneers, and since the Pioneers didn't ground one wire to the speaker frame, I ignored any polarity when soldering the factory speaker wire to the new speakers.

Now, the Visonik amp has 5 (five) wires for the speaker level inputs: left - and left +, and right - and right + and one marked "signal ground."

When I hook everything up, and ignore the signal ground wire, I get audio, but it does not seem to be amplified above what the rest of the speakers are getting. When I hook the signal ground wire to one of the other input ground wires, that speaker gets full power, but the other one only gets low level power. When I move the signal ground to the other negative speaker wire, the other speaker gets full power. Can't get them both to work at the same time.

When I tried to connect the signal ground to both negative speaker inputs at the same time, no sound at all (short?).

Does ground matter on the speaker leads going to the original speakers?

here are the color codes of the wires in my rear doors:

Right rear (pass)
Orange w/red stripe
Purple w/pink stripe (at least it looks purple)

Left rear (drivers)
Grey w/blue stripe
Brown w/white(or yellow?)stripe

Again, I wired my stuff up with no regard for polarity on the speaker leads, but my +12 and chassis grounds are correct.

Stock 97 Explorer V8 AWD with premium audio and 6 disk cd changer in center console.

PS, the subs are two 10 inch in a nice enclosure, and the amp is a 800 watt, or 400 into two channels. Really thumps, and it's only half working!

Thanks

As an FYI, your $99 amp is not putting out anywhere near 800W of power. This can be inferred from its very high power to cost ratio.

Haha yeah... 800W of power at 32 volts while cooled with liquid helium!

How do you know what amp he has?
Some people buy things during times called sales, and sometimes things called "deals" are found... careful it can be tricky!

Anyways back on topic?
do you have the manual for the amp, and what model is it?

Here is the link:

The amp is the v117sx, clearly indicated as 100w x 2 @ 4 ohms....hmmmmm box said 800w.

Matters not, at $99 with an enclosure, 2 ten inch subs, wires and the amp, it's a good deal for my humble needs.

Now if I could just find someone who new the color codes for the low level speaker outputs between the head unit and the amp so I could rewire this think correctly.

I got a live human at their us tech support office who said I need to tap into the signal before it gets to the factory amp, and to use a LOC (line out converter) to convert it to RCA and pipe that into the amp at the rca input location instead of dicking around with the (how 70's) high level speaker inputs (his words).

So, anyone know the color codes for the wires at the headunit (left right - + rear?)

[Wichitagreg]

All installed and sounds great!

Stock Premium head unit and amp.

Low Output Converter attached between stock amp and stock rear speakers: ($19)
Left rear grey/lt blu +
Tan/yellow -
right rear org/red +
brn/pink -

LOC rca jacks into new amp at low level input.

Front and rear stock speakers replaced with walmart pioneer 5x7's ($120 for all four)

CD changer removed and replaced with a FRD-W interface from xmfan.com ($68)

XM Roady Satellite radio ($99 + service)

2 ten inch subs with 2x100 rms into 4 ohms amp ($99)

Total about $400 and it sounds just awsome.

so how loud are these subs? Got any pics of your setup? Glad to here all went well for you.

 

[Wichitagreg]

No pics...sorry. See their web at http://www.visonikcaraudio.com/sub/products/enclosures_2.html

Loud is relative. I have no dB meter

It makes all the glass vibrate so as you can see it in the mirrors.

You can hear it from the house to the street with the windows up.

I can't turn it past 1/2 way on the head unit or I'm afraid I will damage my hearing.

The Amp is V117SX
400 Watt 2 Channel
Amplifier
2 x 100W Rms @ 4Ω
2 x 150W Rms @ 2Ω

You bought this all at pepboys? package deal? How much total? I 'm looking for something to pound better than my crappy 50W single 10" sub and crappy walmart amp.

 

[davesexplorer]

our pepboys just got them in too.... 99+tax I believe.....

 

[Wichitagreg]

two tens in one enclosure, 1 amp (100x2@4ohms) all wires and connections

$99

the speakers are rated 400 wats rms each, 800 peak, that's why the box says 800 watt system.
