I have a double DIN JVC just like that, the AVX640, can't even tell you how many times that screwed with me. I finally got a splitter for $2 just to satisfy my OCD Good to hear it's working!

Hey everybody, newbie to the forums, I figured I'd lurked long enough and it was time to actually ask for help from the pros so I can start helping too I'm planning a build for the coming year (I have a lot of aftermarket suspension, engine, and transmission work to do as well, so it's gonna take some time to get the money), and I'm in need of some advice on amplifiers. I know I'll be spending quite a bit for an amplifier of such high wattage (or two strapped is fine also), so I'm trying to find a... not budget, but good price to watts on an amplifier. Anywhere between 3500 and 4000 watts is perfect. http://www.amazon.com/Lanzar-OPTI4001D-Optidrive-Digital-Amplifier/dp/B006QU3LJU I spotted this Lanzar that's actually CEA-2006 compliant, so I know it puts out it's ratings, but the price comes at a cost, I'd have to run it at 0.5 ohm, and I feel like that's going to require more amperage than at 1.0 ohm because of the decreased efficiency, amperage I may not have. Currently in my 05 Grand Prix I have a DC Power HO alternator (110 amps idle, 250 amps max) with 1/0 gauge Big 3, and an Optima Redtop up front. I'll be upgrading the rear battery (currently a Kinetik HC1200 isolated except when the car is running, not ACC) to an XS Power D6500 (is this overkill?). Maybe even add an extra ground to the alternator, I ground to the casing right now. All wire terminals are soldered. Anyone have any recommendations? And will 1/0 gauge power and ground suffice? I'm working with 4 gauge now because my current amp (Massive Audio N3) only puts out 1400 watts, under full load my voltage drops to about 13.8v, more likely due to my current power wire coming undone recently (it's zip tied under my car, bad idea as it turns out) and missing half the wire, hazard anyone? To those who hate walls of text: 1) Best priced amplifier between 3500-4000 watts. 2) Will running the above amp at 0.5 ohms draw a TON of current like I'd expect? 3) Is an XS Power D6500 overkill as a second battery? 4) Will a single run of 1/0 gauge OFC wire possibly with an extra for alternator ground suffice? Thank you in advance for any input, I hope that I organized this post well enough, I have a ton on my mind right now.

Fi Audio makes some nice subs for a good price, handmade too. Their customer support hasn't been as great recently due to a team member leaving, but I'm sure they'll be back full strength soon enough, their woofers can take some abuse too if you want loud.

Make an MDF ring for possibly improved midbass, I stay away from plastic mounts because of resonance. Like with my front 6.5 Infinity's, on the stock plastic mounts certain frequencies would cause random parts in my door to rattle, not with the wooden baffles. More mass helps I guess.

I feel that it's more to taste, I doubt that overpowering them at 3000Hz is any more risky than at 13000Hz, maybe a little more power handling but not much.
