Verge VGA300M Speaker terminals

I just bought a used Verge mono amp off of ebay, before I wire it up, I wanted to ask this question. On the amp there are 2 positive terminals side by side and 2 negative terminals side by side, when I go to wire my subs, do I use both the positive terminals together or separately, I have never owned a mono amp before so I'm not sure about the speaker connections on the amp.

Re: Verge VGA300M Speaker terminals

Mono amps often have two sets of speaker outputs; this is just to simplify multi-speaker connections. The two positive and negative terminals are connected together internally, so they're effectively the same as one terminal. There's no difference between connecting both subs to the same positive and negative terminals, or using different terminals for each sub; electrically they'll all be connected together either way.

Jl audio g1700

this is a mono block amplifier ,both positives are the same inside the amp and both negatives are the same ,there is 4 terminals to make it easier to wire 2 speakers . Use either positive and either negative ,with this speaker ,inside the box you can wire both positives together and negatives together (parrallel) this should be 3 ohms and the amp should run smoothly ,maybe a little warm but that amp can take it .

KAC-9104D output terminals

ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .

Connecting a subwoofer to a mono amp that has 2 sets of terminals

ok this gets confusing sometimes. Ok first look to see what ohm your subs are. If you have a dual 4 ohm sub When you run that on sub + to + and - to - then that will make that sub 2 ohm. its different on ohm if the sub is say a 8 ohm then putting the wires that way will bring that sub to 4 ohm. Now lets say you have 2 subs that are dual 4 ohm and wire both of them + to + and - to - and go bridge the amp which would be both wires from sub both + together and both - wired bridge on the amp will make it a 1 ohm to the amp. Please post what ohm your subs are and i can tell you alittle more about it

Lanzar optidrive series 4000watts mono block digital compitition class amplifier

Firstly, sorry to to tell you, but their is no such thing as a 4000 watt car amp. Google Ohm's law and RMS .

Check the owners manual or website to find the amps minimum impedance. Usually 4 or 2 Ohms. Next,
check the woofers impedance , If unsure check with a Ohmmeter,
It's actually the resistance,but close enough.

If they are 8 Ohm and you twist those wires together (parallel circuit) your amp will see 4 Ohms.
If they are 4 Ohms (paralleled) your amp will see 2 Ohms.
Do not connect in a series circuit (+ amp terminal to a + speaker terminal and that speaker - terminal to the other speakers + terminal and that speakers - terminal to the - amp terminal) .
It creates phase problems, and sounds like ****.

Most mono amps are really internally bridged stereo amps ,it's cheaper that way, but it limits how low of a impedance they will handle. Read the specs. Use the correct size connectors, scrape off paint for a good ground connection.Use the right gauge wire and above all. Fuse that power lead at the Battery!!!!!!!!
ps . if you have dual voice coils thats another chapter.
Good luck, Sumthin

Alpine 3523 no instructions or wiring

I know this is a little late but I have one and the hookup is very easy, On the right side of the amp there is a six pin plug. Above it it says BATT REMOTE GND. The two pins below BATT are the battery (V+). The pin below REMOTE is the (V+) switched turn on. The two pins below GND are the ground. The rest is simple. Two RCA inputs. The switch to select MONO(R), STEREO, or MONO(L) works as explained. If you want stereo, put the switch in the middle and supply two inputs and two speakers. The MONO(R) and MONO(L) are to select a single input that will supply a single (bridged) output. Connect two speakers and they will supply the same source or connect one speaker to the outer speaker terminals for higher power output. The variable or fixed switch just bypasses the GAIN CONTROL knobs(used for Alpine's 8 pin DIN plug on unit, for older EQ's and head units.

How to install this amp properly?

The amp is a mono amp with only one output channel so it cannot be bridged. You'll use one positive and one negative per speaker. The positive speaker terminals are connected together and the negative speaker terminals are connected together so it doesn't matter which you use for the individual speakers.

Problem with hifonics 1505 class d mono

The positives are connected together and the negatives are connected together. The two pairs of terminals are for convenience. You'd connect one speaker to a pair of positive/negative terminals and you'd connect the other speaker to the remaining pair of positive/negative terminals.

You need to confirm that you have a good signal feeding the amp. If you have another amp in the vehicle, swap the RCA cables between the amps to see if it makes a difference.

You also need to confirm that the speaker are working properly and that there are no broken connections in the wires. If you disconnect the speaker wires from the amp and touch the wires across a D-cell battery (for a fraction of a second), the speaker should pop. if it doesn't, check the wiring to determine why.

Jbl gto 3501 amp

It's a mono amp. There's no bridging with this amp.

The two pairs of speaker terminals are connected together internally. The second set of terminals is for convenience.

Sub hook up to PPI D3000 amp

I'm not familiar with this amplifier but in most cases, if a mono amp has more than one positive speaker terminal and more than one negative speaker terminal, the positives are directly connected and the negatives are directly connected. So  as long as you connect the speaker positive to a positive speaker terminal of the amp and the speaker negative to a negative speaker terminal of the amp, it will work properly.

No sound

you may have a blown speaker...many cd decks will shut off their audio circuits when a speaker is blown to protect from shorting out. Go to the back of the deck and try disconnecting speakers one by one. You will have to turn the deck off and back on each time. Hope this helps!
