Ok, so I just moved last summer and I found out my local install shop wants to charge me my first born for an install so I'm gonna be unlazy and do it myself. I still have my old HU and amp from my last car. HU is a Pioneer P7700 and the amp is a Hiphonics BX1505D. I used to have 2 12" Kicker CVRs and would like something comparable in loudness. But I listen to more Rock now than anything so I'd like something more punchier than deeper. I kinda like the Memphis M series but I haven't kept up on subs lately so I'm open for suggestions. My only concern is I like having truck space now which I had none of with the 2 12s. So would I get what I'm looking for from 1 10 or 12, and how big of a box would I need. Ideally, I'd like to still get at my spare just in case.
Your headunit and amp are fine. Jeeping you spare tire and running a STW enclosure is pretty much going to be out of the question. If it were me, I would run a set of shallow mount 10s (great for that punch in the face rock) or 1 12" sub. The box wouldn't be bigger than 7" deep, 13" tall, and 25" long for 2 10" subs. This box will fit nicely up against the back seat and still provide you wilth plety of trunk space.
+1 I have 1 10" Kicker Solobaric L5 in a small 1' sealed box. those have more bass than my old Infinity subs. I would go with 1 or 2 Infinity's if you listen to rock. those have a cleaner sound than my kicker does...IMO...also, Infinity's aren't that expensive either. I used the 10" Kappa Perfect DVC
Whats practicle to one is over board to another. So what is really practicle? I can answer that! Its the factory Fosgate and Nav. system. Its cool as a grocery getter set up and or if your parents bought you your car and cringe at the mere thought of you even being on here.
No, practicle to me is still having room in the truck, access to the spare tire, not excessive in weight, and sound quality. The factory RF system is not even close to having sound quality, so its out. By practical, I like very clean installs that aren't cluttered. A very clean simple well designed sub box, amp, and hidden wires is very practicle. Especially if you like to run at the track. Its easy to remove, easy to replace, low maintenance, and cost effective. Not to say I don't enjoy custom fiberglass trunks, because I do. But from a business stand point, most of my money and sells come from the young kids that want the "simple" stuff. They can't afford the custom trunks. Therefore I pride myself on making clean, simple, practicle, sound quality systems. Sometimes I do "balls-to-the-walls" bass systems but I don't prefer them. Basically when it comes to stereos I live by the KISS Rule... Keep It Simple Stupid
