system issue

Hello Everyone well im new to this site and i have a issue and was wondering if somone can help me.. I've been asking around but i haven't been getting a answer that will help me... So i'll start to say i drive a 99 Honda Accord I put 2 10" EV DL10X on my deck there mid bass woofers.. Along with Some tweeter forgot the ohmz of it and all...on my door I have Beyma 6MI90 loudspeakers and i have a pioneer premier deh-p500ub as my headunit..and a 7 band clarion EQ... All the voice is begin pushed by a Soundstream Amp trx880.4 and for bass i have 2 10" Mtx and a sony Amp. My problem is this. When Im hearing my music and I hit the turn signals or put up a window anything that uses power the voice on my car fade in and out quickly sounds like a skiping cd.. So i went checked my Alt it reads 14.9 with my system on. So then I go and get a Optima Battery Yellow top Still does it. I read up and i heard about the BIG 3 Upgrade did that as well with 0Gauge wire and it still does it i upgraded all my grounds to my amp and made them 0Gauge and still does it i bought gold plated rca and still I've done so much and im still stuck and dont know what to do but mind you as my voice fades in out for that split second my Subs are still pounding if anyone can please help me i'll really appreciate it Thanks guys for taking your time reading all this. And another question is how should i run all 6 speakers in paralle or series Thank you guys so much hope somone can help me out. Aim:DahandsomeHuslla

I already have that done to my car sorry to mention. But all it did was clear the high pitch/whining noise when the gas was hit

Check the voltage on the remote wire of the highs amp while you have someone turn on the blinkers or whatever else causes the issue.
