Nothing besides the stuff in my sig.

 

v should be A correct?
volt or amp

 

Do your head lights dim when you have the stereo turned up loud? if not then your electrical system is fine and not affecting anything.

If your head lights do dim then start with the "big 3". If that don't solve the problem either a bigger battery or larger alternator is needed.

Now you say you only have a 300w rms amplifier, thats not very large, your car should handle that just fine.

 

I havnt had any dimming..So it must be a coincidence im loosing gas millage. I know this is a car audio forum..but what can I do, upgrade, ect do get better gas millage?

 

K&N Air Filter, drive with a light foot, keep the car's weight to a minimum, tires pumped up properly, A/C off as much as possable during the summer, windows open just a crack, regular oil changes....

what powering the 6x9's? please don't tell me its the head unit

 

its just the head unit, my last ones were and one was broken so i needed a quick replacement.

is this bad?

 

I say yes

cause your 6x9's are designed to take 100w rms, your head unit only puts out 22w rms if that. Your speakers are seriously underpowered, that can hurt them when they are turned up loud. When those speakers die, either buy cheap ones that don't want much power or get a 4 ch amp to power them now along with the front speakers.

 

I do plan on getting an amp eventually..but I cant afford one right now. I need new parking break cables before I do anything.

Is their a store in canada that sells K&N products. Im really liking the idea of replacing the intake and the filter.

 

Going by your sig, the amp for your sub is much larger then what you need, keep the gain down low on the amp. Kinda strange you had to turn the gain up to get more bass, you could be wrecking the sub doing that.
sub amp is rated at 500w rms, one guy claimed to get 654w rms on the birth sheet. the sub is rated at 350w rms so....

 

Well I was getting bass, but not as much as I wanted. Ill turn it down.
