Although a car audio/video/security installer I run a pretty simple system, Alpine HU, [head unit] CDA-7892 and four Eclipse 6.5" speakers, [tweeters disabled on rear speakers.
Front speakers are installed on custom MDF speaker housings and rears are installed in custom MDF and fiberglass cabinets, both front and rears are behind stock grills.
Products I like and recommend...
HUs- McIntosh, if you can afford it.
Alpine, IMO still the best HUs on the market.
Panasonic, if you are on a budget.
Pioneer, Kenwood and Clarion also make an OK product.
Amps- McIntosh and audison if you can afford them.
JL Audio, Alpine, MTX and Kicker
There are more then a few other OK ones.
Speakers- Hertz, Dynaudio, Alpine, Eclipse, JL Audio,
Infinity and a lot more.
Subs, Hertz, JL Audio, Alpine, MTX, Kicker and a few
more.
Best advice I can give for car audio/video/security is buy only from authorized dealers, local retail or online, I always support my local retail dealers for anything I buy, [if avalable].
I have 35 years of car audio installation experience, am also pretty good with car electical and A/C. if you have questions, feel free to ask.
I am not part of the low rider community, please don't hate.
Closest thing to low ride is the 58 Impala convertable tri-power we are working on at the shop right now, [stock restoration]... http://www.airwolfeautoair.com/ 94
PS, question, where did the speaker fit guide go, it was very helpfull?
