I have a few question I hope you can answer for me.
I have a caddillac deville (2000) I used to have a 1200watt Hollywood Excursion amp connected to 4 pioneer premiers 12" subs. I also had a 600watt amp connected to my inside speakers. I had a seperate Red Optima battery aswell.
That system worked just fine, did not dim my lights or anything of that nature.
Ive decided to switch to 2 Kicker L7 12" subs in a ported box. I know that I will need a bigger amp for those L7's.
My question is the following,
Do I purchase the Kicker L7's 2 ohm or 4 ohm's? What amp should I purchase for these subs? how many watts minimun? Can I keep my Hollywood Excursion 1200 amp? Should I purchase any Capacitors? If so How many? Should I upgrade my alternator? (hope not)
I intend on keeping the inside speakers connected with the 600 watt amp I had before. Should I get rid of the extra dry cell battery?
I just do not want to change the alternator. This is a caddillac and has so many different lights, I have HID's in the headlights and foglights. The stock alternator is about 120-160 amps.
Should I just get different speakers instead? If so which ones? I just want 2. If I get the CVR's should it be in a sealed box? Thank you so much , I appreciate everyones help.
They will be going in the trunk of a cadillacdeville. I heard that ported is better when its a truck or suv, bt since its a closed in trunk, I was told that sealed box is better. Any advice??
