sub and amp question help

[DmanVT]

Hi all, i Am upgrading to 2 subs shortly and i need an amp to run them,

The subs are type s alpines ( 300w rms each) DVC @ 2ohms per VC

I have a couple of options and i want to get some opinions on what would be better,

1st option is:

1x 300w rms ( min ) @ 2ohms mono block amp and have each sub voice coil in series ( 4 ohm) and then the subs in parallel ( 2 ohm load )


2nd option is:

1x 600w rms ( min ) @ 2ohms mono block amp and have each sub voice coil in parallel ( 1 ohm ) and then the subs in series ( 2 ohm load)


What would be the difference in running the subs in either options?

Would there be no difference between the two options or would there be a massive difference or a massive problem?

Please help me, Thanks Darcy

Don't mix series and parallel wiring. The lower the impedance level (for subs) the better. Basically the less resistance, the more power an amplifier will make.

Wire them all in parallel and you will have a 0.5 ohm load. Any good 1 ohm stable amp will run lower.

what price range am i looking at to get a 1 ohm stable amp? can you suggest me an amp please?

OAK1200 1200wrms option audio mono block 1ohm stable. A bit more power then you need but you should be able to get one cheap

thanks, i will keep that in mind,

Today i made the custom box, i took my sub out of the old box put it in mine, sounded better i believe anyway i turned the car off after about 20 seconds and then i started undoing the sub out of the box ( took be about 5 mins, then i heard a phhht sound and looked across and noticed smoke pouring out of my amp, i grabbed it and ripped the wires out.

I think its F***** but im going to take it somehwere to test it coz im too scared to plug it in.

I didnt touch any settings, wires or anything between puttin the sub in the second box.

Why would it just decide to blow up?? :'( i'm shattered

Did you disconnect the battery?

 

[DmanVT]

no :/ was i supposed to?

 

[kcpwns]

Yeah...lol...did it blow the fuse at the battery though?

 

[DmanVT]

no it didnt, was i supposed to disconnect the battery just to take the sub wires off?

coz the power was off to the amp, well the red light wasnt on or anything :/ god damn it i never knew you had to take the battery off just for sub :/ i thought that was just for when your dealing with power wires :'(

Wait was the amp disconnect from the power wire or?
Yeah you should always disconnect the battery man
