distortion when turned up or bass is used
 

I have a scdbta60 scosche radio it is a nice radio with bluetooth phone calling and such. I like the radio a lot but im not a big radio Ive always had fast vehicles with a decent radio well here lately Ive wanted better sound quality not like thousand dollar system quality but nice clear quality and i may add a small sub later on but right now i hear a distortion when my radio is turned up especially a song with any bass.

that is my radio specs is that decent? seems like the watts may be low to me but i am unsure. I have the matching scosche speakers and the front "6.5" speakers get distorted with even the smallest amount of bass i keep the bass at -4 and it still happens sometimes. im wondering is it the radio or is it the speakers?

thanks in advance

worth looking into an amp for your speakers, also check to see if you have a hpf feature on your deck (high pass filter) this will allow you to stop the bass being sent to the speakers. if you want more bass look into a sub. also worth setting the eg on the headunit to flat and turning the loud feature off.

im not looking for more bass really. i would just like to turn my radio up without having to put my bass on -4 or -6 lol i think ive narrowed it down to bad front speakers

Quite the opposite unfortunately. Your deck is trying to hard to give you what you want, therefor distorting.

As was already said, you need an amp to drive the speakers. This will liven EVERYTHING up quite a bit and shouldn't distort.

There's always the possibility you may need better speakers after the amp as well, but that's where I would start.

well its only the fronts that distort

^set your hpf correctly

this scosche head unit doesnt have any hpf settings or i would do that

are you sure it doesn't have them in a hidden menu or something? what model is it? if it doesn't and you are sure (and have had a read of the deck manuel to confirm) i'd say your best bet is to either get a better deck or an amp that has a hpf built in.
