Hello! This is my first post here!

I recently bought an Optima and it has the Infinity system w/o navigation.

I was going to go crazy with the system but decided on a more "modest" pair of 12 Solobarics. h t t p s://www.bestbuy.com/site/kicker-dual-12-loaded-subwoofer-black/5760910.p?skuId=5760910
had a few questions I was hoping would be answered here.


First of all that enclosure is rated at 1500 WATTS RMS (750x2) so I was wondering what amount of power I would need to fully push them. Also, will a higher watt amp blow the speakers or will the speakers blow amp if not high enough wattage?!

I wanted to ONLY add the subs in addition to the stock system/head unit etc. I figured I'd use a volume control knob to adjust bass levels. Will this work?

What adapters/additional (other than basic wiring kit) items do I need?

Finally, I would like to know on your guys best advice on HOW to wire it! I read a few threads that said tethering off of or disconnecting the factory 8" and running signal from there?!?!


ANY advice is greatly appreciated and thank you in advance!

BUMP Almost 70 views and no feedback?!
madding that much bass, even with the Harmon kardon speakers is gonna drown out your mids and lows. Keep the 8” factory hooked up to help round out your midrange frequency a little bit because honestly the HK speakers aren’t really like the HK speakers you would buy in a store, they just sound “good enough” for them to slap their logo on it. If you really want great sound that not gonna be overkill I would suggest a new head unit as well. Spend the extra dough on getting an idatalink maestro setup to retain the factory steering wheel controls (if applicable) and the factory amp. If you don’t wanna go that far into it,at least invest in an audio control LC2i and tap into the rear speakers. That way you get a full range signal that you can adjust/boost via the amplifiers low pass filter. As far as an amp, you just gotta shop around.distortion blows speakers, so a 2000w rms @2 ohm amp at the proper settings would do fine. If you ant to run that kind of power I would suggest alsoupgrading your big 3 (alternator, battery, wiring) as well. At the least a 220 amp or better alternator and a second battery with 0g wiring.
