second battery and split charging relays

  • Author

ok thanks but what about the alternator isnt that too much power ?

More batteries. Go on www.streetbassers.co.uk and ask there ;)

How does the mk2 even stay in one piece with all that bass???

well i've had to put a whole lot of insulation underneath the speakers

You're gonna need an uprated alternator for sure, as well as a battery or two. Whats the output of the amps?

A couple of drycell batterys charged off a split charging system would help you out no end. Running it off the standard battery will eventually kill the battery.

ok thanks, but how can i find out what type of alternator to use, which one will fit to my engine ? both ams give out about 3400W peak which is about 1700W rms

you will need 2 red top batterys for that lot I'm guessing as they are high charge high output batterys but there not cheap!!! you will also need a split charge system thats found on a caravan and then you will have to put a very beefy high spec alternator on it, try GSF parts and if they dont have them they will know where to get one from.

just out of interest..why use so many mutant subs, why not a few good quality subs, and what are you using for treble/midbass?

ok thank you for help.

i bought them very cheap that is why i am using them. for midbass/treble i use 5 coaxial speakers, there is no tweeters in the car cause all i wanted was a very loud car.

Is that a power cap I see :o

That must sound very interesting with the subs all being different distances away from you.

yep that is a capacitor :)

the sound is very interesting especially when everything is vibrating :(

just out of interest..why use so many mutant subs, why not a few good quality sub

Wouldnt investing in a couple of good quality ones sound much better and look much better. A set of rockford punch 8-)

I wouldnt even bother with a power cap. Useless. Buy some Big yellow batteries from forklift trucks on ebay. Give a lot more power than red top and yellow top optima POS batteries. What cuft per sub is the enclosure? Looks waaaay too small.

Yellow top batterys, split charge relay.

Have you upgraded the existing battery and alt wiring with 0awg yet?
