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 120 amp
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.
Cadillac is a small vehicle to have two L7s in. Make sure you dynamat the heck out of the trunk so you don't rattle anything loose. The L7s have pretty impressive excursion and are capable of really moving air and building pressure, especially in a small cabin. If you are the kind of person who likes to blast your subs, take caution with the setup and fine tune them well. I am not worried about the subs as much as the vehicle... I've seen L7s pound hard enough to literally break professionally built boxes with 1" MDF on the face.
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??
