[QUOTE="stones, post: 8629204, member: 540734"] I have a 2017 Mustang with the base audio system. It ****** so I made some changes. Based on it's glowing reviews on Sonicelec' I added an Earthquake DBXi 12" dual 4ohm in a 1.8cft tuned to 34hz (tried 1.3 sealed as well both recommended by manufacturer) powered with a monoblock class D delivering 700 Watts rms clean. Bass *****, whole stereo ***** in general but this bass is criminal. Added epicenter Kinda neat effect but not musically accurate, annoying after time, no response under 40hz. Took out epicenter added LC2i Massive peak at 50hz, can only play 40hz to 60hz, checking voltage on amp outputs show a terrible bell curve. So.. time to throw some money at it (Canadian money so prices higher).. I can buy a Kenwood DDX25BT Double Din CD DVD Player Bluetooth XM Radio Install Package for a thousand bucks. [URL="https://www.ebay.ca/itm/Kenwood-DDX25BT-Double-Din-CD-DVD-Player-Bluetooth-XM-Radio-Install-Package/391896160542?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649"]https://www.ebay.ca/itm/Kenwood-DDX25BT-Double-Din-CD-DVD-Player-Bluetooth-XM-Radio-Install-Package/391896160542?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649[/URL] or I can buy a Metra AX-DSP Digital Signal Processor With AX-DSP-FD2 2013-18 Ford, for $450 bucks [URL="https://www.ebay.ca/itm/Metra-AX-DSP-Digital-Signal-Processor-With-AX-DSP-FD2-2013-18-Ford-F150-Mustang/122681450426?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649"]https://www.ebay.ca/itm/Metra-AX-DSP-Digital-Signal-Processor-With-AX-DSP-FD2-2013-18-Ford-F150-Mustang/122681450426?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649[/URL] $450 bucks is a much easier hit to the wallet, would the Metra work well?. The Earthquake sub, lots of hype in the reviews for this sub, my impression is that it sounds like someone glued a brick to the cone. Does this sub have terrible SQ?, it's loud but seems really sloppy and insensitive. Would the NVX XQW12 give me good sealed box performance?, I want rich, accurate bass preferably in a small sealed enclosure to save trunk space and weight. I have already picked up some replacements for the front door speakers and an amp to power them, perfect imaging not important to me just needs to be decent, my first priority is fixing Fords 70hz to 9000hz frequency response from the HU. I appreciate your help thanks. [/QUOTE]
