![]() Power is rated at 120x4 and 500x1 at two ohms, or 100x4 and 300x1 at four ohms. A signal steering switch allows all five channels to be driven with one, two, or three pairs of RCA inputs. These options make ideal to use with any type of source or vehicle. The SRPM1100.5D has three different modes available for turn-on: either the traditional 12-volt trigger or signal sensing via actual musical signal or DC offset sensing. A removable cover allows easy access to the controls and connections for installation, as well as provides protection once the amp is installed. Power and speaker cables are secured with set-screw-type terminals, and will accept four- and 12-gauge cables, respectively. The design places all of the controls and connections along the length of the front panel. The amplifier is very compact for a high powered five-channel product, measuring only 12 x 5.25 x 2 inches. The SRPM1100.5D is built around a high efficiency Class-D topology, using a high performance chipset from International Rectifier. This time we’ll be taking a closer look at the five-channel SRPM1100.5D amplifier, designed to be the only amp you need for the whole system! Known as the RPM series, for Recreation, Powersport, and Marine applications, these amplifiers have been designed and built to stand up to the rugged demands of the marine and off-road markets. Now, in addition to the regular car audio products, there is a line of marine/off-road oriented amplifiers. The Cerwin-Vega Mobile brand has continued the 50-year legacy of delivering high performance audio products to the most demanding customers. Modern receivers use sub pre-outs (pre-amplifer outputs) rather than a powered amp channel, so you need an active rather than passive sub when using modern receivers (active means self-amplified).Anyone who has an interest in audio will be very familiar with the name Cerwin-Vega. No advantage to old gear when it comes to subs, as subs often weren't available for older gear and often poorer performers than today's subs (vintage merely means old more in audio than anything actually vintage). Sub box size varies by driver size and box design, not particularly age ported boxes tend to be larger than sealed. Subs are the way to go generally for deeper extension than speakers provide, and are generally just more capable than even most "full range" speakers. You mention one set hooked up at the surround/bi-amp terminals, hopefully you're just using the surround modes in the avr rather than bi-amping (which is more a marketing thing for avrs and intended for speakers with "bi-amp" terminals). Knowing how you have arranged the speakers would help as well as what sound mode/processing choices you're using on the receiver. On the Yamaha, the remaining speaker spaces are 2 R&L Surround, a 1 R&L Center - Would a sub be placed into the Center? Would it be suggested to pull more bass out to get a sub?Ī large one is fine, because I am going for a vintage look, and they tend to have larger cases from what Ive seen luckily I have the space. I've enjoyed reading about Hoffmans Iron Law as well, thank you. Now I know when I was running it from my phone it sounded like poop because it was through the wrong input. The smaller ones are into the Front and the large ones into the Surround/Bi-Amp. They are not hitting super deep but they are woofers and not subs if I understand correct. Ran through preamp into Audio 1 - all four speakers and everything through the Yamaha.įuses were good on the large. Okay so I have figured it out for the most part with everyones help. Was playing music to test them from a phone into the phono.Īlso I have enjoyed this forum and the willingness to help, and I am learning from this process. Even doing just the Yamaha with the D-9 didn't have great sound. Ran only the JVC with the AT-8 and had the similar problem. Running both sounded like the volume was changing on its own, and had fuzzy buzzy distortion. ![]() JVC has the two AT-8, and the Yamaha have the D-9. That receiver went bad, and had a music head do the current set up. Turntable currently getting ground wire fixed. Originally had all 4 going through 1 receiver and only listened to a turntable. Larger D-9 ran through JVC into R & L Front * Other options: Center, Surround, Surround Back/Bi-Amp, Extra SP Zone 2 + Presence ![]() Smaller AT-8 ran through Yamaha into R & L Front I am going to list my current set up and any feedback on what to do or other amp/receiver options would be greatly appreciated. Hi everyone, I have 4 Cerwin Vega speakers from my father and am having trouble powering them.
