Is 7900 watts good for a car sound system?

Question

I have a 1983 Jaguar XJ6 and have a total of 7900 watts of sound system equipment, is this good enough or is this TOO MUCH for a car to have?
2 amps- 1200 watts total
4 10 inch subs- 3200 watts total
4 8 inch subs- 2800 watts total
4 speakers- 700 watts total

If this is too much, please tell me what I should take out and leave in.

Answer 1

Sparky is right. It is your amp RMS rating that shows you your total watts.

The numbers on the speakers are the maximum watts they can handle before they burn up. They are usually watts at specific ohms.

Answer 2

You don't have 7900 watts!

Your 1200 watts total from two 600 watt amp is more likely to be 200 watts RMS each.

Since your total actual wattage is 400 RMS, you are greatly underpowering those speakers/subs. This won't damage them, as long as you have the gains set correctly, but they won't be utilized to their fullest potential.

When figuring watts, you have to go by the amps RMS watts output, not by what the speakers can handle.

Newby is wrong when he said "speakers blow faster with lack of power than they do being over powered". You can never underpower a speaker, but this is NOT to say it can't be blown.

OMG, vart50 is so wrong on so many points I can't even list them here. Especially the last entry:

"remember if there over 8 inches never run 1 sub 1 amp.. waste of potential. never run 4 subs 1 amp.. might blow some circuits.. always run subs in parallel.. and bridge your amps.. you can even run your speakers two 2 chanells.. and then either run a 8 inch sub off the other 2 channels.. of if its a 2 channel amp then bridge it across."

This is ALL a load of crap!!!

Answer 3

Your measurements are wrong.. It sounds to me like you have a 1200 watt system total (RMS).. You need more amps.. YOU will blow these speakers if you run it with what you have.. "speakers blow faster with lack of power than they do being over powered" Don’t always look for wattage.. A system will sound better on how the power is delivered and received.. FYI check the parameters on the speakers vs the amps.. Make sure they are compatible.. But in your situation install it, listen and learn..

Answer 4

Whatever power u want to go with, is your choice. But why mix 10" subs with 8" subs???

That causes an overlap of low frequencies where your ears can't distinguish the mid bass from low bass. It's a nightmare to adjust a system like that right when sizes are so close.

Replace the 8" subs with 6" subs to achieve for a true mid bass & low bass system.

Or keep the 8" subs, and replace the 10's with 12's...

Answer 5

Obviosly you had it installed and didnt do it yourself.. cause other wise you would know what you need ans what you dont. First of all yeah if you had 8 thousand watts of power then id say wow. But in this case you dont.. (lets say i put 20 -200 watt speakers in my car in a box not connected to anything i dont have 4000 watts of power i have 0.. the power comes from your amps.. now your 1200 W amps probably are about 900 rms.. your 1200 is your peak. Basic laws of stereo keep your amps for subs and amps for other speakers seperate.. unless you want rediculas distortion and or wasted power.. what you have for amps depending on how you have it set up could make you loose hearing or sound no louder than my laptop speakers.. use 1 for your subs..take out every thing but 3 of your tens .. run them in parallel. to 1 of your amps.( your 8s are worthless.. cause if you looking for higher pitched base notes.. the tens are perfect...)(i acually like the sound of 2 -10s.. and a 12.. (ive played around with all types and combanations.) run your other speakers to your other amp.. and thats all you need.. remember to cut of the bass frequencys to you speakers.. at about 175 Hz. and your sub low pass frequencys should be about 95HZ to cut out lots of disstorion and high pass at about 42Hz to not over draw current. for those low low notes might hurt your amp if you run the 3 subs in parallel at 1.33 omhs.. try run your 4 speakers to each chanel. on your amp if its a 4 channel.. other wise put 2 in parallel and run your two sets of speakers to each but you are now running at exteme watage for those speakers.. so dont turn up too loud.. just after it hurts your ears.. (not talking about bass here) cause past that and your probably putting too much in and might blow a speaker.. my advise buy a 300 watt amp just for you inside speakers.. and mabey put in 2 more 12s with that replace 1200 watt amp. .. hope fully ive taught you somthing..do what you want

Answer 6

judging from the way you have figures your total wattage I would suggest you take your car to an audio specialist that knows what they are doing because you actually only have 2400 w. of amp and 26,800 w. of speakers. So I don't know where yo ucame up w/ 7900 w. system.

Answer 7

Firstly, thats not how you would measure the watts. Either measure it by its RMS or DB's obtained.

I would say you need more amps cos the 2 that you need seem hardly sufficient for all those subs. Maybe you dont need all those subs anyhow.

Answer 8

you have 2400 watts you might need another amp let me know i have a sony xplode 1000 watts / bostwick 400 watts and rockerpunch 160 watts

Answer 9

its a load! but its cool...i bet ur ghetto and like poundin down the street and wake people up. im suprised ur battery didnt die. or do u have 80000000000000 watts of battery power on a 1200w amp

Answer 10

i thinck it is to much try taking out the 8" subs
