Subwoofer upgrade options

[rumtumdrumr]

Do you know if the GV70 "Select" models have an amp?
I have the NON Lexicon audio system (7 speaker).

 

[rumtumdrumr]

Going into the door is not required. Tap into the speaker wires that go to the factory amp.

My installer told me all of the wiring was in the rear, right side of the vehicle.

Travis, do you know if the GV70 "Select" models (like mine) have a factory amp? Pretty sure they do in the same location. Just Cannot confirm this.

I cannot confirm, but it has to have an amp of it has the Lexicon audio. I doubt they use a different head unit with an internal amp on the Select models.

See this article about locatimg the amp.

GV70 Amp and speaker tap location

FYI - I know there are a lot of variation of the stereo for the GV70, but make sure if you are taping into a wire going from the amp to a speaker that it is a full range signal in that line. some systems limit the bass sent to certain speakers. Would stink to tap into a wire and find out later the signal is being filtered.

I need every inch of my trunk. My kid plays lacrosse and I golf, so putting a box in the rear isn't an option. I've seen cars that have sub/amp conbos mounted in their spare tire, is that an option on the GV70?

Depending on how much bass you need, check out my thoughts in post #31 of this thread. If you remove the spare tire all together there should be more than enough room for a low profile sub and enclosure.

It is my belief a person could build a custom enclosure and use a low profile sub driver and create an enclosure that takes up little to no cargo space. I've also posted someplace about an install I did in a previous vehicle using a bazooka bass tube. I created quick connect wiring harnesses to allow me to very quickly and easily connect and disconnect the bass tube. I also used quick connect tie down straps for the tube itself. The end result was added bass that if I needed extra cargo space I could spend 1 minute and disconnect the tube and relocate it to the garage or the backseat. When I could spare the extra room in the cargo area I could hook the tube back up in about 2 minutes and enjoy extra bass again.

Not sure if either option is something that could work for you, but I wanted to share and provide options.

Same here. We're empty nesters, but still want all my trunk space available. A sub in the trunk is a no-go for me. There are aftermarket active subs that are round and are designed to be mounted inside the spare tire. However, on my GV70, that is where the scissor jack and components are located and I am not willing to part with it.

My son's Mazda 3 GT had a sub mounted inside the spare tire as part of his stock system. Bass it added was minimal and so far back in the car, hardly felt. We added a Kicker Hideaway underseat sub to his car with a separate wired volume control, and whoa, incredible difference. It is not car rattling bass like a bigger dedicated sub install shown on this thread, but at volume, its enough to make his rear mirror vibrate. I also had a Hideaway in my 2013 Santa Fe XL, and it was more than plenty. I just want a bit of bass to complement the music, not looking for headache creating bass. So, an underseat active sub is likely to be my approach, if I choose to do anything at all.

Would be curious if anyone has thought about swapping out the stock sub under the drivers seat, add an amp and likely run new wires. That would be the least "intrusive" option as the only new component to locate somewhere in the vehicle is an amp (likely under the seat).

My plan is to keep all the tools, just wedge them in that empty spot to the left of the spare. From what I've heard, most stock trunk mounted spares are garbage. I had one in an old Infiniti FX35 that did next to nothing. The one I'm considering for my GV70 is VEGA 12" 150W RMS 2 Ohm Active Subwoofer or the shallow version VEGA Shallow 12" 150W RMS Spare Tire Powered Subwoofer

Yes...saw that one. If I recall, had good reviews. If you give this one ago, would be interested in your thoughts on performance.

I looked into seeing if I could easily replace the OEM underseat driver. I had picture of the driver and enclosure for the GV70, but can't find the pictures right now. The GV70 subs appeared very similar to the GV80 sub pictures that are attached to this post. There isn't much space and even building a custom enclosure appears to be very difficult.

Trying to think outside the box, I wonder if an outboard DSP could be used to boost the bass of the existing system for those who want to add a little more punch.

This reminds me a bit of when i tried to update my Explorer System. In the first 1-2 years of the Explorers existence no local stereo shop wanted to touch the system to add a sub because there was no information available with how everything worked. A couple years later there were plug and play wiring harnesses and a method to upgrade the entire system from Sync 2 to Sync 3 with CarPlay. It sucks being on the cutting edge and wanting to have easy solutions.

I had no idea these were actual mini sub boxes! Seems almost asinine to have to add a third sub to the car to get bass. Would be nice if genesis at least added a subwooder level control to the radio options. Thanks for the writeup btw.

Damn, sorry, not sure how I missed your reply. Thanks. Yes, something along these lines would be ideal, at least for me. Not interested in taking up useable space with a sub. While I have some skill, not enough to figure this out on my own. Hoping someone will give it a go.

A very long time ago, I had a 2006 Infiniti FX35 with a Bose system. It had a factory spare tire sub that was pretty useless. Someone came up with a mod that helped to raise the output of the sub. If you didn't turn it up too much it did a great job of adding a little more punch. I'm not an electrical engineer but I'm hoping this inspires someone to come up with something similar for our cars.

Idk if it just depends what you're listening to or what. Most of what I listen to (electronic, specifically mostly future funk and nu-disco) has very good bass in my GV70, better than the 12 in a ported box I had in my Cruze, and better than the optional Kicker 10 I had in my WRX. Most of what I listen to has mid bass that's more than covered by the door speakers and the under seat subs seem to have no issue filling in the sub bass. When YT Music decides to put a dubstep track in my discover mix I'd go as far as to say it pounds.

I've measured the in cabin response. The Lexicon system measures fairly flat and as it should for a 'reference' system, but the problem is most people are use used to bass levels that are 5-8db or more higher than what a flat response should be, so they hear the Lexicon system and thing the bass is very limited.

From a post I made this past summer....

I think a lot of people are used to the over EQ'ed sound from other systems. Some people equate over amplified bass as better sound or better reproduction. It all boils down to personal taste, but the Lexicon system provides a fairly faithful reproduction of the music it is fed, the goal of any hi-fi system.

... this system is one of the better factory systems. Certainly not the best I've heard, but it's solid, maybe number 3 or 4 on my list. I also think the volume range and settings are great. In my last premium factory system, at lower volumes the increments were a PITA. If I wanted background music while I chatted with my passenger, at one low volume setting the music was drowned out by road noise and at the next volume increment the music was a bit too loud and took away from the conversation. With the GV70, I like the smaller increments at the lower volumes as it really lets me fine tune the output. Once I get to 50-55, the increments increase nicely because at that point I'm trying to jam and fine tuning it's a thing.

If you want some quality tracks to judge the system, try the tracks I have listed below

• John Beck - Jazz Variants drums start around the 1:10 mark.
• Michael Jackson - The Way You Make Me Feel
• Natalie Merchant - The Peppery Man (Leave your Sleep album)
• Hans Zimmer - Imagine the Fire (The Dark Knight Rises soundtrack)

Again, none of these tracks will shake your teeth from your mouth. NONE of these tracks should if you listen to the music the way the sound engineer/producer created the music. If you are used to bass that is over emphasized and you think anything less is unacceptable, then you will be disappointment with the Lexicon system.

Some great knowledge on this thread. I appreciate everyone sharing their knowledge and experiences here.

Someone was asking about where the stock amp was and how to get to it. This guy made a Youtube video showing how to remove the side panel and gain access for those that are interested...https://www.youtube.com/watch?v=06x14DpMGak&t=11s

However, I think @TravisF and @Timelessvance have the best solution for those of us that feel the bass is underwhelming.

I love the simplicity of getting that added bass without all the need for custom enclosure and taking up space in the trunk. Yes, perhaps it takes up more space than the custom fab box on the side of the trunk, but then it seems it would be a heck of a lot easier to simply detach the cables, remove the box and then use the trunk for those days that you need it.

Many moons ago, I was super into this stuff. Here are some photos of the custom trunk enclosure I built using the spare tire space in my Honda Accord. I'm not in college anymore and I got kids, so I need to use the trunk as a trunk.

But I have been out of the game a bit. I'm trying to decide between the Rockford Fosgate Punch P300-12 and the rockford fosgate p500-12p, which have both been recommended on this thread. One of them appears sealed whereas the other is ported. One being 300 watt vs 500 watt.

What would be the difference between these two (other than the $$$ spent). Looking for some advice / knowledge on this, so I can make the decision. Thanks!

The P500-12 is better; it is on another level from what I have read. I installed the P300-10 simply because of the space limitation in the footwell of the car.

If space is not a concern and you want a better sub, the P500-12 is a better choice. I was planning to maybe upgrade to the P500-10 (10 inches), but it does not exist, and from what I have heard, they will not make one.

I tried the 11in JBL that is made for the spare tire well but unfortunately it was too large and had to return it.

Did you test the sound out though?
Was it any good ?
