Recently I had my subs die on me as I didn't have the correct amplifier for them or have it setup correctly, my mistake. But oh well I've been wanting to redo some of the equipment that I went cheap on and what I rushed before.
Currently I have a Alpine CDA-105 headunit, 4 JBL 6X9" 3 Way rated for 300w max power, I have a JBL 4 Channel 600w amp powering those. For the subwoofers I had 2 JBL 8" 800w max power, powered by a bridged Kenwood 4 channel 640 watts max power amplifier that was given to me for free and was only suppose to be a temporary thing, but funds were tight and I never got around to replacing it with the correct setup.
I'm going to be keeping the headunit, the 6x9s and the JBL amplifier. I'm replacing the 4 channel Kenwood with a Monoblock Kenwood. It's rms power is 4 ohms: 500 watts x 1 chan, 2 ohms: 900 watts x 1 chan and 1 ohm: >900 watts x 1 chan. I ordered 100 ft of 12 gauge with 295x2 Strands and 25 ft of 8 gauge with 735x2 strands. I wanted to make sure I had enough wire this time, unlike last time I didn't have enough wire and the wires were pulled tight. All new gold plated terminals and a grounding block. I purchased 2 120mm pc fans to keep the box cool for the amplifiers and 2 relays to turn the fans on. Here in a couple of weeks I am planning on ordering 2 10" Polk Audio MM1040. From my research they should do just fine for what I want to do with them. Here's the specs on them.
Peak: 700 watts
RMS: 350 watts
Impedance: Single 4 Ohm
Polymer woofer cone
Butyl rubber surround
Carbon Composite Basket is very lightweight and will not flex during use
Heavy duty terminals can be used with speaker wire up to 8 gauge or two twisted pairs of 12 gauge
Klippel Distortion Analyzer results in the best possible performance at any listening level
2" High temperature copper voice coil
Frequency response: 24-200 Hz
Sensitivity: 91 dB
Here's pics of my current installation. I'll update this thread as progress on the build goes.
And the new stuff waiting to be installed.
