I need help

Ok I really dont know that much about steroe systems and well my truck it has a nice face plate and MXS speakers but the problem is my truck its running on glass packs almost sounds like straight pipes and well i have to have my volume up quite a bit so i can hear it but when i actually want to hear it to were its loud it cuts out and the lights and face plate fade out when the bass hits and i tried using my friends speakers and does the same thing :banghead: any thing i should do?

buy new mufflers and try sound deadning it.

dude im never gona put new mufflers on i love the sound of the 30" glass packs but i just want to know how to make my steroe system not cut out when it gets loud and hits the bass

do you have external amps ... like for the bass. If you do, you probably need a bigger alternator.

:1: make sure you have sufficient power, and sounds like you need a new alternator.

yea i think i might need a new alternator :banghead: cuz even when i have my lights on then dim when im idling

and so i need like a new alt. and buy an amp? cuz i have no amp right now

holy cow, you are saying your lights dim just from amp on the headunit ?

ok my headlights when i have them on they dim when my truck is idling

and my faceplace lights and the cab lights dim when i get a bass hit

fyi my truck is old its a 1978 GMC 1/2 ton Sierra running stalk sept the engine swapd it out for a big ol 350 bb but like the alt. carb and everything else is stalk and i replaced the water pump last year

sounds like you have some electrical issues ......

try adding 0 guage wire to the big 3. if your problem continues, maybe you have a bad alternator? My civic has a 70ampere alt, and though that's weak, my lights are fine. i'm gonna doubt that you have a several thousand dollar competition system that would use that much power, so something's F'ed with your electricals.

well this truck is a 1978 GMC 1/2 ton seira so its old running same wires sept the stereo system and thats it everything else is stalk
