Car Sub and Home stereo question
 

Well my car is off the road for a while until i get some repairs done and it passes its MOT.

I wanted to take the sub out my car so i know it was ok and not at risk of being stolen.

Anyway i have connected my Sub up to my home stereo. Obviously my stereo has a built in amp

Will this be ok?

This is pics of the sub in my room now

Re: Car Sub and Home stereo question
 

does the impedance of the sub and stereo match would be a good starting point :)

Re: Car Sub and Home stereo question
 

Firstly, I wouldn't because you could damage it if it isn't hooked up right. Subs are for low frequency repsonse, and you need something called a crossover to filter out anything too high for the sub (like vocals). If your home stereo has a subwoofer output though, that's ok, as that is a crossover.

Secondly, you need to find out what the RMS and peak wattage of your home stereo is, or you could blow your sub. Also, I hear, that heavily underpowering a sub can damage it also. If the RMS wattage of the sub is higher than the home stereo and the peak is lower, then you can use it, but don't push it. If the RMS wattage of the home stereo is higher than the sub, then don't use it at all.

I assume you are transforming the power from AC 240v to DC 12v?

I have no idea how to check that :D

So tell me how :D

My stereo speakers have 6 wires coming from them

2 for tweeter
2 for mid range
2 for the sub on the speakers.

I have plugged the sub in with the sub wires.

I will get the stats of my stereo in a bit

Re: Car Sub and Home stereo question
 

to find the RMS and peak wattages you need to look at specs in the back of the manual. The impedance will be in too.

You may find some or all of the above on the back of the unit too.

unless it is an active sub , he wont need to :angel:

Re: Car Sub and Home stereo question
 

Quite right, don't mind me, I am still half asleep...

Re: Car Sub and Home stereo question
 

What do you mean by that?

Re: Car Sub and Home stereo question
 

Don't worry about it, I wasn't paying attention.

Whats the RMS wattage on your sub?

Re: Car Sub and Home stereo question
 

Well i got told at the shop about 700W.

But i been told shops exagerate to sell

So i dunno

Re: Car Sub and Home stereo question
 

Is that RMS or peak though? Shops can't really exagerate because the figures are set by the manufacturer, and you need to follow them to prevent damaging the sub. If you ask them what the power output is, they'll always quote peak as that is higher, but RMS is more important. The only way you can find out what both figures are is to look at the manual, or the net for it (or on the back of the sub).

In case you are wondering about the difference RMS is more like an average power output, i.e. what it consistently can handle, whereas peak is a very occaisonal spike in power.

Re: Car Sub and Home stereo question
 

Well i think the RMS is 350W

Re: Car Sub and Home stereo question
 

does it have a 12v input or not , basically , does it have a built in amplifier ??? :)

However boombastic your bass may be, do make sure to remove that little pink & white plastic handbag you have there. Even the the saucy Abi Titmus poster you have on the door will not fully cancel this out.
