U need to hear and decide for yourself. To make a major upgrade of the Shaker Pro is a PIA. Adding a sub to the factory sub, not pretty easy. I'm a stereo guy, I would have done a full stereo delete if I could have. Not sure how anyone here can tell you what sounds good to you.
I went for easiest, no damage connections. I removed the woofer from stock enclosure. I have the wires from stock amp, coming out from hole in back of stock encloser. The wires are connected to LC2i. So the LC2i is seeing amplified signal meant for stock subwoofer. After adjusting LC2i, I...
What I'm really looking for is whats under the red cover. Ive seen nice connectors and Ive seen people just shove the wire in there. I have never seen the hardware like the Mustang has for where the battery cable attaches to the post. Is the small nut on top for tightening cable clamp?
I have the factory sub. I unhooked the sub and connected to the wires that were supplying factory sub. Which, in other posts, people said didn't work. I didn't want to pull off of rears, because usually I have them faded out. All can be put back to factory when it's time trade up.
Im too old for pretty. I have the P2 mounted in ported bass bunker box. Rear firing in trunk. LC2i did wonders for roll off. Much more bass and I would have had to start amping front end. Still want to upgrade tweeters and center someday. Pics after I clean up the mess.
So I finally got what I wanted. Booming bass for Gorilla Zoe and Drake.
I have Shaker system with sub. My radio adjustments are 3/4 high, flat mid, flat bass. Hits as hard as with aftermarket HU. If you are just adding bass, forget getting in the kick panel or flattening signals.
