What should i do?!?!?

hey guys, i have a problem with my head unit blinking, i think i've told you guys before, and now i've decide on two things, i am either going to buy a $125 speaker amp, that puts out 50rms X 4 to stop the blinking, and also to have a high pass filter, or sell my head unit, and put down another $125 (which is about $275 total) for another head unit, that has a high pass filter, and anythign but alpine, because i dont want it to blink like it does now lol.. yea so anyways which should i do? i have a alpine 9807, i replaced the stock ground with a 14 gauge (i might get a bigger ground) but it still blinks so buy speaker amp, or.. buy new head unit with more features etc?? thx

you have a power problem if a headunit's built-in amp causes blinking

you have a power problem if a headunit's built-in amp causes blinking

would it be the head unit itself, or should i check my wiring, i wired everything correctly, and the power wire runs thru a fuse, i think 15 amp or so before it gets to the battery, the 14 guage im using for ground is much bigger than the stock ground, which was like 18 or 20 gauge

I ran an 8 Ga power wire from the battery to power my accessories in the front.
