Hey guys, I’m a new member, also a pretty hardcore fan of Steve Meade and the awesome stuff he does at his shop, and always follow his videos. I’m an automotive technician here in Tucson, Az, and on my off time, I go to my friends shop and bum around as he is an authorized retailer for b2, Sky High, Sundown, ds18 and even has his own line of badass equipment. I sometimes do installs for him as I’ve had tons of experience in the install field over the years and can pretty much do an install in anything and always make it work.
However, with this build, I’ve been clueless as to what the issue is that I’m having. First off, I own a 2006 Toyota Avalon Touring that DID NOT come with the factory JBL system. So my setup is as follows...
Pioneer Avh-p2440nex double din deck with the pac steering control unit and Audiovox backup camera
Front: B2 Audio Reference 6.3 3-way components with the elite midrange option & Metra 6x9 to 6.5” mid-woofer adaptor
Rear: DS18 Elite 6.5” coaxial with Metra speaker spacer
4 Channel Amp : b2 audio ma1000.4 with sky high 4 gauge ofc kit
Sub Amp: JL Audio RD500/1 2ohm amp wired to 1 ohm at the sub which is;
Sub: 12” Rockford Fosgate p3 dvc 2 ohm In a ported a-trend prefab box with a M.E.S.A. 4 gauge OFC kit
My battery is just a new ac delco, and my alternator has been upgraded from the factory 100amp to the 130amp from the “Avalon limited”, but I haven’t had much of a chance to upgrade the charging system much yet...although, I bought the car in may 2019...she’s getting there. The trunk has also been dyna-matted, so no rattles...
Both wiring kits go straight to the battery from the amps and each have their own in-line fuse. All grounding points have been ground to bare metal before mounting to the chassis. I also purchased 60’ of Sky High 16 gauge speaker wire with gold connectors for the speaker terminals, and used ring terminals at the crossover. I bypassed all the factory wiring, so all the new wire is going through the door harnesses and straight from the amp to the speakers, so I know this isn’t a factory wire issue, and I have the pioneer deck so I know this isn’t a DSP issue since I have all DSP’s and time alignment turned off, and have had no difference using them or not. I have tried different wire at first that I had purchased from Walmart just to temporarily use to wire up the amp, but recently upgraded to this sky high stuff...and I have pictures of the entire process from start to finish, so if any pics are requested, I can definitely share.
The issue I am having is, the sound is incredible at a lower volume level, but once I get up around 25 on the deck and the speakers sound like they wanna go louder, I’ll turn it up more and it sounds like the tweeters just shut off, or the sound fades from what sounds like Chrystal clear HD audio, to what sounds like a Lo-fi music from the 1920’s..now, I’ll be clear on this, they still sound great when I turn it up and they still sound clear, but they lack that crystal clarity that they have at lower volume. So when I then turn it back down again, the clarity comes right back and the transition is overly obvious and kind of embarrassing to be honest...I don’t really even have the ma1000.4 turned up at all, and I know these speakers can go a lot louder than I’m putting to them...but I just cant figure out what the issue is at this point....my Boston Acoustic pro60’s never did this, neither did my alpine type r components, and neither did my kenwood components...
my buddy seems to think that getting another less powerful 4 channel amp and running the crossovers as active would be the only real way to fix this issue...anyone have any ideas as to what’s going on?!? Am I missing something!?! There’s that crossover switch on the 4 channel amp that says like x1 and x10 or whatever that I know nothing about...and this is really frustrating...it’s like, just when the music sounds so good and you wanna turn it up more, the sound quality goes to shit...
I wanna fix this because I have a pair of b2 xm8’s in a custom ported box and a b2 rage 2500.1amp to power them, at which point, I’ll also upgrade the amp wiring to 1/0 gauge OFC Sky High stuff.....but for now these components are driving me crazy...I’ll get on my phone so I can share the install pics...my iPad doesn’t have them...
