Alright here's my problem. My B-days coming up and I cant decide what I should upgrade in my 95 ford explorer 4 door. As we speak I have 2 SoloBaric L7 12's dual 2ohm. In there own custom built box. Powered by a Kenwood 1800W Class D Mono Amplifier with Low-Pass Crossover. Plus 2 Audiobahn 10's each powered by their own Sony Xplod 500 watt amp. In a box meant to hold 3 subs but I have my cap in there to hide the leds at night. Also have a box that sits behind the drivers seat on the bench seat. Its a Jenson 8 powered by a Visonik amp. Dont know the specs for that amp or sub. I already have upgraded door speakers, also added two extra ones for the rear doors. By the way all 6 of my door speakers are wired to my factory jbl amp. I have a Big battery under the hood Mega-Tron 3 I believe 850 cca 1050 ca. Ive already run 0 gauge wire for the big 3. Also upgraded my power wires going to the amps I have 2 sets of 0 gauge wire ran. I'm just stuck at what to get next? replace the 2 xplods? add more batteries? Add a new alternator ? Equalizers? better door speakers? Id just like to make my audio better. Toss ideas at me I'm all ears.
