Is connecting the sub-woofer amp to the car battery a problem?

[Kulasangar]

Hi all,

I actually got a sub-woofer fixed to my 20-year-old car (Peugeot 406 d8) today from a professional auto-shop and I"m wondering whether this would mess up the car in the near future?

As a note I would like to mention that, the worker who fixed this connected the amp, to the car battery. Just wanted to know, whether it would cause any huge issues as an overall, to the car or it's wiring system?

Thanks.

what is the ampere rating of the amplifier? Normally it should be OK if its made for automotive usage the alternator should provide enough juice.

Use a cap to smooth out the spikes in the power take up.

Yes, the positive line for high power amplifiers connects to the battery directly. This is normal. Just make sure that the line is protected (with an inline fuse) and the fuse is located as close to the battery as possible. This will protect the car in case a short circuit happens. 

As for your question about potential issues to your car, it all depends on the current the amplifier draws versus the current the alternator produces to keep the battery charged.  Now that the amplifier is already installed, you can get your charging system checked out at full load (headlights on, AC on, stereo on high volume)  to determine if the alternator is keeping up with the power draw requirement.

I couldn't actually notice the rating, but I can get back to you on that. But then the people who did the job did all the amplifier testings using the multimeter and made sure it's getting proper juice.

Alright, noted and thanks a bunch.

Possibly the good thing I've read for the day , and yes they've kept the fuse close enough to the battery. Regarding the load test, they actually tested with high volume and with headlights but not with the AC though. I might have to test it again and see then. Can I do the test on my own at my place, or is it better to take the car over there and do it? Thank you so much for the point outs.

The D8 's batt case only allows a 55-65 amp DIN battery.

it cannot be upgraded as the space is limited.

the only upgrade is the alternator. The factory valeo unit is adequate for a small system. as it's been put in with the factory A/c.

Thank you so much @Twin Turbo for making it clear. (y)

Ok, wanna look at the rest of the system? Would be great to see some pics of your toy,..

 

Cheers

Umm seems like I've got an idea now, regarding how much amps does a d8 battery could supply and how it works. If there's anything else can I ping along this thread?

Thanks.

The battery is there to start the engine. the alternator runs the show.

That's right. Got it!
