Wiring Solo Baric L7 to 1 ohm or 4 ohm help please

[OGredneck73]

Thats the reason why people are riled up when you say you think your amp is too powerful for the sub when its barely enough to move the sub at 1 ohm. 4 ohm.

I never said it was too powerful I said "I know it is enough to push one sub" ?????IDK where you got that or why anyone would get riled up at that.....Thanks for the tuning help I will use your advice but I have had many different sub amp setups so I am pretty familiar with that process....and I checked out all the bad reviews along with the good ones and there were more Good videos for the amp than Bad.

The dealer put the sub in the box for me told me it could only be wired @ 1 ohm or 4 ohms

I looked up the specs for the sub and only found wiring option for 2 ohms I was confused at that point so I felt the need to ask...Thanks for the solid info

I just bought a 12" L7 and when I bought it I was giving him the specs on the amp I am running which is a 4000 watt Soundstorm SSL EVO which is 4000 watts 1ohm stable, 3000 watts @ 2 ohms, and 1600 watts @ 4 ohms. I only have 1 sub and am wondering if I should wire the sub to 4 ohms to be on the safe side because he wired it to 1 ohm and I have checked it with a meter and it reads 1.2-1.3. I know this sub won't handle 4k @ 1ohm so should I switch it to 4 ohms?

Wire the amp for a 1 ohm load and crank it up (have fire extinguisher nearby), if it doesn't go up in flames and/or shut down from thermal overload... it is 1 ohm stable.

Take a deep breath................................ and keep us posted..

A 4 ohm sub with dual voice coils can be wired for 8 ohm 4 ohm or 2 ohm..

A 2 ohm sub with dual voice coils can be wired for 4 ohm 2 ohm or 1 ohm..

To achieve a lower Impedance simply wire the voice coils in parallel.

To achieve a higher Impedance simply wire the voice coils in series.

A single 4 ohm sub with dual voice coils CANNOT be wired for 1 ohm..

The only reason for dual voice coils do is give the installer more wiring options, nothing less, nothing more..

So back to my question should I trust the wiring he installed which read 1.2/1.3 ohms or just wire it to 4 ohms?

 

[OGredneck73]

or 2 ohms if it is possible but I clearly asked him about 2 ohms and he clearly stated the sub could only be wired at 1 or 4

A dual 2 ohm subwoofer can be wired to 4ohms or 1ohm.

1 ohm would be wired parallel. (all negitives together and all positives together)

With imp rise you will be fine at 1ohm.

Awesome just what I needed thanks alot ya'll have a great evening //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Had many sub amps. Still ******* clueless. Buys 4000 watt amp for $150 for a L7.

Where are these people coming from

 

[gstokes]

Let's be realistic, a 4000 watt amplifier would draw 290 amps with a 13.8 volt source.

You probably have a 70 amp alternator and out of those 70 amps you can dedicate 50 amps to the sound system.

50 amps times 13.8 volts equals 690 watts but that's with an amplifier that is 100% efficient.

Class A amplifiers are 30% efficient.

Class B amplifiers are 50% efficient.

Class AB amplifiers are 60% efficient.

Only Class D amplifiers are "theoretically" capable of reaching 100% efficiency.

The amplifier you chose is a Class D design so that's a plus BUT it only has three 40 amp fuses so 40 amps x 3 fuses = 120 amps and 120 amps x 13.8 volts = 1656 watts.

So, you will need at the minimum a 150 amp alternator to produce that 1656 watts with a 13.8 source voltage..

Let's say you have a 16 volt charging system, now all you need is 103 amps to produce 1656 watts so a 120/130 amp alternator would suffice..

Oh ****, I forgot to factor in voltage drop so now you need even more current to produce the same amount of power..

A good way to tell how much power an amplifier can produce is to multiply the number of fuses times the fuse rating..

If an amplifier has a single 50 amp fuse then the most power you can expect that amplifier to make is 690 watts, 13.8 x 50 = 690..

If an amplifier with three 40 amp fuses draws more than 120 amps what's going to happen, it'll blow the fuses..

Your amplifier would require three 100 amp fuses before it could even dream about making 4000 watts..

Hope this helps bring you back down to earth and let's you be more realistic with your power expectations..

only leaving 20amps for car?

not going to work. a/c alone is 30amps. heaters on high about 20amps, lighting,,ect..

when i got my truck it had a stock 78amp alt. with just heat on my lights dimmed ..... and ya was a good alt.

just sayin.

Good point, I was being too generous with available current //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Just want to thank you all for the help I am happy with my SSL EVO 4000D it consistently puts out 1850 watts to my 1 L7 even though it says 40000 i know I know but 129$ for 1800 watts is ok with me. Thanks again!

I hope you set the gain thinking it does over 1000 watts.
