[QUOTE="PhillyGuy07, post: 3046807, member: 577384"] To start this off, I'm a newbie when it comes to car audio and I just started doing research into it a few months ago. I'm going to try and make this as simple and clear as possible and hopefully somebody can help me out with this and give me some advice: I drive a 97 Chevy Lumina, I've already replaced the back two factory speakers with some decent JL's and I plan on buying some good speakers for the front (not sure which kind yet). I'm also going to be getting 2x 12'' Eclipse SW61248XD's subs from my cousin for free and also a Eclipse EA2000 2/1 Channel Amp with that also that I plan on using. [B]Specs on the Eclipse Subs:[/B] o Model - SW61248XD o Size (In.,CM) - 12, 30.5 o Impedance (OHMS) - 4 Dual Coil o Max Rec Amplifier Power (WATTS PEAK / RMS) - 1000 / 500 watts o Peak Power Handling - 1000 Watt o Frequency Response - 28 Hz - 250 Hz o Sensitivity - N/A o Woofer Material - Aluminum o Surround Material - Santoprene o Top Mounting Depth - N/A o Bottom Mounting Depth - N/A o Mounting Diameter / Length - N/A o Weight - 15lbs each [B]Specs on the Eclipse EA2000 2/1 Channel Amp:[/B] o Digital Hybrid Power Capacitor o 25 Farad o Digitial Blue Display (Amperage/Voltage Meter) o Blue LED Lights o Low Profile Mounting System o Chrome Mounting Brackets o Working Voltage : 16DCV o High current, high efficiency MOSFET power supply o ?Easy Tune? top-mounted controls o Sleek, low-profile design with front mounted input and output terminals o Variable 30-500 Hz 18 dB high-pass crossover o Variable 50-500 Hz 18 dB low-pass crossover o Variable 0-8 dB Bass Boost o Flush-mount wire terminals o Illuminated Eclipse logo power indicator o Clipping indicator LED o Amplifier Type: 2-channel o RMS Power @ 4 Ohms: 60W x 2 @ 14.4V o THD at 4-Ohm RMS Power: 0.05% o Bridged RMS Power @ 4 Ohms: 175W x 1 @ 14.4V o Speaker Level Inputs: no o Preamp Outputs: yes o Built-In Crossovers: HP/LP o Bass Boost: 18 dB o Frequency Response: 20-20,000 Hz o Signal to Noise Ratio: >90 dB o Fuse Rating: 30 amps Now my question is can that amp power both those subs nicely or would that not be enough? It's only a 2 channel amp so from what I understand I don't think it can really power BOTH the subs? Would I be better off using the amp I already have to just power my front two speakers, then letting my back 2 speakers just run off the head unit, and then go out and buy a new (better) amp for the subs? If so what should I get and would this work? Any idea on the setup would be nice, right now I'm trying to do research and find the best possible setup with what I already have. I'm willing to buy another amp if needed and maybe spend extra on whatever else would be needed. Any help would be appreciated! [/QUOTE]
