amp cuts out for bass

[Driver]

can any1 tell me why my amp might be doing this?

i put the bass on and it just cuts out on heavy parts off bass

[Driver]

also makes the car inside lights dim, if that means anything

[PlATiuM]

lights dim cause of the current the amp draws. but mine does that also Alpine amp most newer good amps have clipping protection to stop cookin ur sub and amp. best bet is to turn it down at the amp, mine cuts out still if i crank it really high. u just need to find the right balance took me 8months in my lancer before i was happy than sold it and brought a system for my mr2 happy with it for now seeming cant get to big a stereo in here

[Driver]

yea i did turn it down but the level i get it at wich it doesnt cut out is just as good as the stock car speakers

[PlATiuM]

hrmm, try putting all the eq's flat on the headunit, gain on the amps low, and even the freq cut off low. than set those low/high/flat thingos if u got them

than turn ur headunit to 3/4 or 4/5 of the way up than adjust ur cross overs on the amp than adjust the gain up slowly just before clipping. thats how i tune mine and works most the time.

and im not pissed with you cause u gotta r34 i tune ur stereo u give me ur car deal?? hehe

Maybe the amp just doesn't have enough power to run your sub then? Sounds to me like your overdriving the amp

Driver came into irc chat and asked the same question, and my response was the same as ferni's.... with an analogy that "it's the same as asking us 'why is my room dark' and then not telling us how many lights are in the room, or how many watts the globes are"

In order to diagnose this problem, we need to know the following:

1/ What sort of sub

2/ What sort of amp

3/ What sort of car battery

[Driver]

i got a feeeling it might be the car battery

as i did try start the car after i asked the question and would ya know.. the battery is flat

i needa get it charged up sumhow then ill try again

[Driver]

ahh

and thats exactly wat the problem was, the battery was too flat to power the amp properly - works perfect now

[SKY031]

Try not to use the stereo when the car is off if possible

Get yourself a 1 Farad cap.

The current draw from the Sub amp is sucking too much power and the amp is protective itself.

Same thing happened in my Calais.

The Cap gives the Amp the stored instant energy it needs.

BASS OUT

[Driver]

it works wickedways at the moment - no need for a new amp

i just have a crappy battery and as SKY031 said i just gota take it easy when the cars not running

[hippy]

get a yellow top!!!

[cLoWn]

get a cap even if its running sweet now still get one

[Driver]

whats a yellow top?

and cap is a capaciter? (spelling)

[cLoWn]

cap is a capaciter? (spelling)

yeah thats a cap now go and buy one it will stop your lights dimming and what not worth the money

[BryanB]

bass junky nailed it for you mate, your amp quite simply draws too much current from the battery at one particular moment, and the battery can't give the amp the current it needs at that one particular moment, which results in the amp going into safety mode and your bass cutting out....

i would recommend getting a capacitor as well as they stop yours amp cutting out by supplying a constant power to the amp

[paulr33]

get a good battery with a high cold cranking amps level

[Fhrx]

Might be a good time to mention we have Optima's on sale at the moment.

[martydaman]

you need 1 farad of capacitance for every 1000 Watts of power your speakers (subs) use... im guessing a 1 farad cap would suffice for your situaltion
