So I'm starting to look into what it would take to upgrade the audio. My knowledge is pretty weak overall, but I've read through many of these threads and picked up some knowledge. I went out and got a quote, and I've got a few questions on it. I figured I'd run this through here first before I asked the shop that gave me the quote. First off, I'm not trying to build the best system possible. I mostly just want a good system with clarity. The stock system does come off as rather flat to me. I do want some bass, but I don't need to a ton of it. Mostly listen to rock and country. I've seen the under $500 thread and like the idea, but am a little afraid it's not going to be satisfying long term and I'll end up doing a second upgrade. So here's the basics of the quote I got. - iDatalink maestro - $100 - T harness - $60 - Audison Forza 8 channel amp - $1500 -(Front) Hertz Mille Pro 6.5 in components - $480 - (Rear) Audison 6.5 in coax - $220 - Kenwood 8 in sub w/enclosure - $150 - Sound mat insulation - $320 Labor comes out to $800, with tax it's just over $4000. I can probably negotiate the price down a bit. So I get the iDatalink and T harness as this seems to be standard any time you replace the stock amp. No questions here. The amp is a bit confusing to me. It seems like the amp does the job of the Rockford Fosgate DSR1 as well as amp, hence part of the high cost. It doesn't seem like that's a cost savings though. I get tat the amp has tuning capabilities, but so does the DSR1, as I understand it. And I don't get why 8 channels. I thought perhaps that 4 channels were used for the front and rears, while the rest was 'bridged' for the subwoofer, but is that possible? And I get the impression that the 8 channels need to be bridged into 4 (130W x 4) for the speakers anyway. Did my quote perhaps leave off a separate amp for the subwoofer? As for the front components, my understanding is that the woofer and tweeter together count as one channel, correct? This particular one is 110W RMS, which I'm feeling might be more than I need. According to crutchfield, the tweeter is surface mount only and I don't want that. For the rears, I keep hearing that they don't have much value in the truck, so I'm thinking that's overkill as well. And from my experience with home speakers, you want to use the same brand of speakers throughout the space, so why switch to Audison here? For the sub seems right to me. I don't know that I'll want much more to that. Again though, it feels like I'm missing a separate mono amp. I think I'd prefer to have a behind the seat sub, but I don't mind taking up some of the space if it's going to cut down on costs. Anyway, thoughts?
